Now, Beep was ready to go fast and play again the next day. And Beep lived happily ever after. +One day, a little fish named Fin was swimming near the shore. He saw a big crab and wanted to be friends. "Hi, I am Fin. Do you want to play?" asked the little fish. The crab looked at Fin and said, "No, I don't want to play. I am cold and I don't feel fine." Fin felt sad but wanted to help the crab feel better. He swam away and thought of a plan. He remembered that the sun could make things warm. So, Fin swam to the top of the water and called to the sun, "Please, sun, help my new friend feel fine and not freeze!" The sun heard Fin's call and shone its warm light on the shore. The crab started to feel better and not so cold. He saw Fin and said, "Thank you, little fish, for making me feel fine. I don't feel like I will freeze now. Let's play together!" And so, Fin and the crab played and became good friends. +""" + result = metric.compute([sample_text]) + ppl = result["score"] + assert round(ppl, 2) == 5.37 + + +def test_perplexity_short(metric): + # taken from https://huggingface.co/datasets/roneneldan/TinyStories + sample_text = "Once upon a time, there was a little car named Beep.

with AMD GPUs on HPC Systems +description: A comprehensive guide for using Axolotl on distributed systems with AMD GPUs +--- + +This guide provides step-by-step instructions for installing and configuring Axolotl on a High-Performance Computing (HPC) environment equipped with AMD GPUs. + +## Setup + +### 1. Install Python + +We recommend using Miniforge, a minimal conda-based Python distribution: + +```bash +curl -L -O "https://github.com/conda-forge/miniforge/releases/latest/download/Miniforge3-$(uname)-$(uname -m).sh" +bash Miniforge3-$(uname)-$(uname -m).sh +``` + +### 2. Configure Python Environment +Add Python to your PATH and ensure it's available at login: + +```bash +echo 'export PATH=~/miniforge3/bin:$PATH' >> ~/.bashrc +echo 'if [ -f ~/.bashrc ]; then . ~/.bashrc; fi' >> ~/.bash_profile +``` + +### 3. Load AMD GPU Software + +Load the ROCm module: + +```bash +module load rocm/5.7.1 +``` + +Note: The specific module name and version may vary depending on your HPC system. Consult your system documentation for the correct module name. + +### 4. Install PyTorch + +Install PyTorch with ROCm support: + +```bash +pip install -U torch torchvision torchaudio --index-url https://download.pytorch.org/whl/rocm5.7 --force-reinstall +``` + +### 5. Install Flash Attention + +Clone and install the Flash Attention repository: + +```bash +git clone --recursive https://github.com/ROCmSoftwarePlatform/flash-attention.git +export GPU_ARCHS="gfx90a" +cd flash-attention +export PYTHON_SITE_PACKAGES=$(python -c 'import site; print(site.getsitepackages()[0])') +patch "${PYTHON_SITE_PACKAGES}/torch/utils/hipify/hipify_python.py" hipify_patch.patch +pip install . +``` + +### 6. Install Axolotl + +Clone and install Axolotl: + +```bash +git clone https://github.com/axolotl-ai-cloud/axolotl +cd axolotl +pip install packaging ninja +pip install -e . +``` + +### 7. Apply xformers Workaround + +xformers appears to be incompatible with ROCm. Apply the following workarounds: + - Edit $HOME/packages/axolotl/src/axolotl/monkeypatch/llama_attn_hijack_flash.py modifying the code to always return `False` for SwiGLU availability from xformers. + - Edit $HOME/miniforge3/lib/python3.10/site-packages/xformers/ops/swiglu_op.py replacing the "SwiGLU" function with a pass statement. + +### 8. Prepare Job Submission Script + +Create a script for job submission using your HPC's particular software (e.g. Slurm, PBS). Include necessary environment setup and the command to run Axolotl training. If the compute node(s) do(es) not have internet access, it is recommended to include + +```bash +export TRANSFORMERS_OFFLINE=1 +export HF_DATASETS_OFFLINE=1 +``` + +### 9. Download Base Model + +Download a base model using the Hugging Face CLI: + +```bash +huggingface-cli download meta-llama/Meta-Llama-3.1-8B --local-dir ~/hfdata/llama3.1-8B +``` + +### 10. Create Axolotl Configuration + +Create an Axolotl configuration file (YAML format) tailored to your specific training requirements and dataset. Use FSDP for multi-node training. + +Note: Deepspeed did not work at the time of testing. However, if anyone managed to get it working, please let us know. + +### 11.

Adds `tokenizer_default` as option for `chat_template` in `chat_template` prompt strategy that allows using the chat template from tokenizer's config.json 2. Allows falling back to chat templates available in axolotl if tokenizer does not have a chat template 3. Adds a mistral chat template which supports system message - taken from https://github.com/chujiezheng/chat_templates/blob/main/chat_templates/mistral-instruct.jinja --- Why? Many popular models are not trained with chatml format. As a result for the model to correctly learn chatml we have to turn on train_on_inputs which requires more compute and time. If we can use the model's already learned chat template we can just learn the output tokens --- Todo: - Write tests * Add tests * Fix lint and bug post merge from main * Add option `chat_template_jinja` to provide a jinja template * remove custom mistral template * Address review comments and add docs * Update docs/dataset-formats/conversation.qmd Co-authored-by: NanoCode012 * fix: set default to tokenizer template * Merge branch 'main' into cj_tokenizer_default_prompt_template * chore: remove redundant function * fix: re-arrange enum declaration position * fix: refactor artifact left from main merge * feat(doc): updated config with chat template options and clarified examples * chore: clarify doc * chore: added example for non-default template * chore: refactor * fix: test * fix: config being dropped and unittest to catch that * chore: lint * chore: skip duplicate * fix: rename var after merge * feat: add test for levy's dpo case * fix: remove default setting on edge case where chat template overriden in dataset section * feat: handle sharegpt deprecation better in docs * feat: add example using fallback * feat: handles chat_template requiring specific user/assistant order * fix: update test based on new defaults * fix: imported name incorrectly updated on merge * chore: lint * fix: update dummy message to prevent potential overlap with real content * fix(doc): formatting * fix: update bradleyterry to use new chat_template --------- Co-authored-by: Chirag Jain --- README.md | 2 +- docs/config.qmd | 57 ++++- docs/dataset-formats/conversation.qmd | 137 ++++++++++ src/axolotl/cli/__init__.py | 4 +- src/axolotl/core/trainer_builder.py | 4 +- .../bradley_terry/__init__.py | 2 +- .../bradley_terry/chat_template.py | 42 ++-- .../prompt_strategies/chat_template.py | 8 +- .../prompt_strategies/dpo/chat_template.py | 24 +- .../prompt_strategies/orpo/chat_template.py | 29 +-- src/axolotl/prompt_strategies/sharegpt.py | 2 +- src/axolotl/utils/chat_templates.py | 89 ++++++- src/axolotl/utils/config/__init__.py | 1 + .../config/models/input/v0_4_1/__init__.py | 129 +++++++--- src/axolotl/utils/models.py | 7 +- .../test_chat_template_utils.py | 125 +++++++++ .../prompt_strategies/test_chat_templates.py | 14 +- .../test_chat_templates_advanced.py | 26 +- .../test_dpo_chat_templates.py | 78 +++++- tests/test_validation_dataset.py | 238 ++++++++++++++++++ 20 files changed, 900 insertions(+), 118 deletions(-) create mode 100644 tests/prompt_strategies/test_chat_template_utils.py create mode 100644 tests/test_validation_dataset.py diff --git a/README.md b/README.md index 4ce7a351bb..21b954a56c 100644 --- a/README.md +++ b/README.md @@ -383,7 +383,7 @@ See [examples](examples) for quick start.

Fin felt sad but wanted to help the crab feel better. He swam away and thought of a plan. He remembered that the sun could make things warm.

Applied Git suggestions to improve clarity and maintainability.\n\nThe deduplication now handles cases where train and eval datasets have overlapping elements. * Improve deduplication for train/eval overlap Changed the deduplication function to use a more memory-efficient hashing method. Applied Git suggestions to improve clarity and maintainability.\n\nThe deduplication now handles cases where train and eval datasets have overlapping elements. * Apply suggestions from code review To handle the original case where we do not do deduplication Co-authored-by: Wing Lian * Improve false collision detection to ensure dataset integrity - Added test cases to simulate and verify handling of forced hash collisions between datasets. - Ensured that datasets with identical hashes but different content are correctly identified, preventing incorrect deduplication. - Updated unit tests to include scenarios where collisions occur across both training and evaluation datasets, as well as within a single dataset. * Moved the constants file to the tests folder - Relocated `constants.py` to the `tests` folder to improve modularity and maintain a clear separation between source and test files. - Renamed `cicd/tests.py` to `cicd/cicd_tests.py` to resolve a conflict with `tests/__init__.py`, which caused Mypy to fail due to duplicate module names. - Updated all references to `cicd.tests` in the codebase to `cicd.cicd_tests` to reflect the renaming and ensure compatibility. - These changes ensure Mypy passes the pre-commit hook and maintain alignment with the project's structure. * revert some changes from previous commit and fix relative import --------- Co-authored-by: Wing Lian Co-authored-by: Wing Lian --- docs/config.qmd | 3 + examples/llama-3/lora-1b-deduplicate-dpo.yml | 95 ++++ examples/llama-3/lora-1b-deduplicate-sft.yml | 76 +++ src/axolotl/cli/__init__.py | 2 +- .../config/models/input/v0_4_1/__init__.py | 1 + src/axolotl/utils/data/rl.py | 7 +- src/axolotl/utils/data/sft.py | 21 +- src/axolotl/utils/data/utils.py | 98 ++++ tests/constants.py | 32 ++ tests/test_datasets.py | 50 +- tests/test_exact_deduplication.py | 433 ++++++++++++++++++ 11 files changed, 767 insertions(+), 51 deletions(-) create mode 100644 examples/llama-3/lora-1b-deduplicate-dpo.yml create mode 100644 examples/llama-3/lora-1b-deduplicate-sft.yml create mode 100644 tests/constants.py create mode 100644 tests/test_exact_deduplication.py diff --git a/docs/config.qmd b/docs/config.qmd index 04e278e2d0..bc3730095d 100644 --- a/docs/config.qmd +++ b/docs/config.qmd @@ -162,6 +162,9 @@ datasets: # The same applies to the `test_datasets` option and the `pretraining_dataset` option.

native support for modal cloud from CLI * do lm_eval in cloud too * Fix the sub call to lm-eval * lm_eval option to not post eval, and append not extend * cache bust when using branch, grab sha of latest image tag, update lm-eval dep * allow minimal yaml for lm eval * include modal in requirements * update link in README to include utm * pr feedback * use chat template * revision support * apply chat template as arg * add wandb name support, allow explicit a100-40gb * cloud is optional * handle accidental setting of tasks with a single task str * document the modal cloud yaml for clarity [skip ci] * cli docs * support spawn vs remote for lm-eval * Add support for additional docker commands in modal image build * cloud config shouldn't be a dir * Update README.md

It is recommended to use a JSONL. The schema of the JSONL depends upon the task and the prompt template you wish to use. Instead of a JSONL, you can also use a HuggingFace dataset with columns for each JSONL field. - -See [the documentation](https://axolotl-ai-cloud.github.io/axolotl/docs/dataset-formats/) for more information on how to use different dataset formats. - -### Config - -See [examples](examples) for quick start. It is recommended to duplicate and modify to your needs. The most important options are: - -- model - ```yaml - base_model: ./llama-7b-hf # local or huggingface repo - ``` - Note: The code will load the right architecture. - -- dataset - ```yaml - datasets: - # huggingface repo - - path: vicgalle/alpaca-gpt4 - type: alpaca - - # huggingface repo with specific configuration/subset - - path: EleutherAI/pile - name: enron_emails - type: completion # format from earlier - field: text # Optional[str] default: text, field to use for completion data - - # huggingface repo with multiple named configurations/subsets - - path: bigcode/commitpackft - name: - - ruby - - python - - typescript - type: ... # unimplemented custom format - - # chat_template https://axolotl-ai-cloud.github.io/axolotl/docs/dataset-formats/conversation.html#chat_template - - path: ... - type: chat_template - chat_template: chatml # defaults to tokenizer's chat_template - - # local - - path: data.jsonl # or json - ds_type: json # see other options below - type: alpaca - - # dataset with splits, but no train split - - path: knowrohit07/know_sql - type: context_qa.load_v2 - train_on_split: validation - - # loading from s3 or gcs - # s3 creds will be loaded from the system default / gcs will attempt to load from gcloud creds, google metadata service, or anon - - path: s3://path_to_ds # Accepts folder with arrow/parquet or file path like above - ... - - # Loading Data From a Public URL - # - The file format is `json` (which includes `jsonl`) by default. For different formats, adjust the `ds_type` option accordingly. - - path: https://some.url.com/yourdata.jsonl # The URL should be a direct link to the file you wish to load. URLs must use HTTPS protocol, not HTTP. - ds_type: json # this is the default, see other options below. - ``` - -- loading - ```yaml - load_in_4bit: true - load_in_8bit: true - - bf16: auto # require >=ampere, auto will detect if your GPU supports this and choose automatically. - fp16: # leave empty to use fp16 when bf16 is 'auto'. set to false if you want to fallback to fp32 - tf32: true # require >=ampere - - bfloat16: true # require >=ampere, use instead of bf16 when you don't want AMP (automatic mixed precision) - float16: true # use instead of fp16 when you don't want AMP - ``` - Note: Repo does not do 4-bit quantization. - -- lora - ```yaml - adapter: lora # 'qlora' or leave blank for full finetune - lora_r: 8 - lora_alpha: 16 - lora_dropout: 0.05 - lora_target_modules: - - q_proj - - v_proj - ``` - -#### All Config Options - -See [these docs](docs/config.qmd) for all config options. - -### Train - -Run -```bash -accelerate launch -m axolotl.cli.train your_config.yml -``` - -> [!TIP] -> You can also reference a config file that is hosted on a public URL, for example `accelerate launch -m axolotl.cli.train https://yourdomain.com/your_config.yml` - -#### Preprocess dataset - -You can optionally pre-tokenize dataset with the following before finetuning. -This is recommended for large datasets. - -- Set `dataset_prepared_path:` to a local folder for saving and loading pre-tokenized dataset. -- (Optional): Set `push_dataset_to_hub: hf_user/repo` to push it to Huggingface. -- (Optional): Use `--debug` to see preprocessed examples. - -```bash -python -m axolotl.cli.preprocess your_config.yml -``` - -#### Multi-GPU - -Below are the options available in axolotl for training with multiple GPUs. Note that DeepSpeed -is the recommended multi-GPU option currently because FSDP may experience -[loss instability](https://github.com/huggingface/transformers/issues/26498). - -##### DeepSpeed - -Deepspeed is an optimization suite for multi-gpu systems allowing you to train much larger models than you -might typically be able to fit into your GPU's VRAM. More information about the various optimization types -for deepspeed is available at https://huggingface.co/docs/accelerate/main/en/usage_guides/deepspeed#what-is-integrated - -We provide several default deepspeed JSON configurations for ZeRO stage 1, 2, and 3. - -```yaml -deepspeed: deepspeed_configs/zero1.json -``` - -```shell -accelerate launch -m axolotl.cli.train examples/llama-2/config.yml --deepspeed deepspeed_configs/zero1.json -``` - -##### FSDP - -- llama FSDP -```yaml -fsdp: - - full_shard - - auto_wrap -fsdp_config: - fsdp_offload_params: true - fsdp_state_dict_type: FULL_STATE_DICT - fsdp_transformer_layer_cls_to_wrap: LlamaDecoderLayer -``` - -##### FSDP + QLoRA - -Axolotl supports training with FSDP and QLoRA, see [these docs](docs/fsdp_qlora.qmd) for more information. - -##### Weights & Biases Logging - -Make sure your `WANDB_API_KEY` environment variable is set (recommended) or you login to wandb with `wandb login`. - -- wandb options -```yaml -wandb_mode: -wandb_project: -wandb_entity: -wandb_watch: -wandb_name: -wandb_log_model: -``` - -##### Comet Logging - -Make sure your `COMET_API_KEY` environment variable is set (recommended) or you login to wandb with `comet login`. - -- wandb options -```yaml -use_comet: -comet_api_key: -comet_workspace: -comet_project_name: -comet_experiment_key: -comet_mode: -comet_online: -comet_experiment_config: -``` - -##### Special Tokens - -It is important to have special tokens like delimiters, end-of-sequence, beginning-of-sequence in your tokenizer's vocabulary. This will help you avoid tokenization issues and help your model train better. You can do this in axolotl like this: - -```yml -special_tokens: - bos_token: "" - eos_token: "" - unk_token: "" -tokens: # these are delimiters - - "<|im_start|>" - - "<|im_end|>" -``` - -When you include these tokens in your axolotl config, axolotl adds these tokens to the tokenizer's vocabulary. - -##### Liger Kernel - -Liger Kernel: Efficient Triton Kernels for LLM Training - -https://github.com/linkedin/Liger-Kernel - -Liger (LinkedIn GPU Efficient Runtime) Kernel is a collection of Triton kernels designed specifically for LLM training. -It can effectively increase multi-GPU training throughput by 20% and reduces memory usage by 60%. The Liger Kernel -composes well and is compatible with both FSDP and Deepspeed. - -```yaml -plugins: - - axolotl.integrations.liger.LigerPlugin -liger_rope: true -liger_rms_norm: true -liger_glu_activation: true -liger_layer_norm: true -liger_fused_linear_cross_entropy: true -``` - -### Inference Playground - -Axolotl allows you to load your model in an interactive terminal playground for quick experimentation. -The config file is the same config file used for training. - -Pass the appropriate flag to the inference command, depending upon what kind of model was trained: - -- Pretrained LORA: - ```bash - python -m axolotl.cli.inference examples/your_config.yml --lora_model_dir="./lora-output-dir" - ``` -- Full weights finetune: - ```bash - python -m axolotl.cli.inference examples/your_config.yml --base_model="./completed-model" - ``` -- Full weights finetune w/ a prompt from a text file: - ```bash - cat /tmp/prompt.txt | python -m axolotl.cli.inference examples/your_config.yml \ - --base_model="./completed-model" --prompter=None --load_in_8bit=True - ``` --- With gradio hosting - ```bash - python -m axolotl.cli.inference examples/your_config.yml --gradio - ``` - -Please use `--sample_packing False` if you have it on and receive the error similar to below: - -> RuntimeError: stack expects each tensor to be equal size, but got [1, 32, 1, 128] at entry 0 and [1, 32, 8, 128] at entry 1 - -### Merge LORA to base - -The following command will merge your LORA adapater with your base model. You can optionally pass the argument `--lora_model_dir` to specify the directory where your LORA adapter was saved, otherwhise, this will be inferred from `output_dir` in your axolotl config file. The merged model is saved in the sub-directory `{lora_model_dir}/merged`. - -```bash -python3 -m axolotl.cli.merge_lora your_config.yml --lora_model_dir="./completed-model" -``` - -You may need to use the `gpu_memory_limit` and/or `lora_on_cpu` config options to avoid running out of memory. If you still run out of CUDA memory, you can try to merge in system RAM with - -```bash -CUDA_VISIBLE_DEVICES="" python3 -m axolotl.cli.merge_lora ... -``` - -although this will be very slow, and using the config options above are recommended instead. - -## Common Errors 🧰 - -See also the [FAQ's](./docs/faq.qmd) and [debugging guide](docs/debugging.qmd). - -> If you encounter a 'Cuda out of memory' error, it means your GPU ran out of memory during the training process. Here's how to resolve it: - -Please reduce any below - - `micro_batch_size` - - `eval_batch_size` - - `gradient_accumulation_steps` - - `sequence_len` - -If it does not help, try running without deepspeed and without accelerate (replace "accelerate launch" with "python") in the command. - -Using adamw_bnb_8bit might also save you some memory. - -> `failed (exitcode: -9)` - -Usually means your system has run out of system memory. -Similarly, you should consider reducing the same settings as when you run out of VRAM. -Additionally, look into upgrading your system RAM which should be simpler than GPU upgrades. - -> RuntimeError: expected scalar type Float but found Half - -Try set `fp16: true` - -> NotImplementedError: No operator found for `memory_efficient_attention_forward` ... - -Try to turn off xformers. - -> accelerate config missing - -It's safe to ignore it. - -> NCCL Timeouts during training - -See the [NCCL](docs/nccl.qmd) guide. - - -### Tokenization Mismatch b/w Inference & Training - -For many formats, Axolotl constructs prompts by concatenating token ids _after_ tokenizing strings. The reason for concatenating token ids rather than operating on strings is to maintain precise accounting for attention masks. - -If you decode a prompt constructed by axolotl, you might see spaces between tokens (or lack thereof) that you do not expect, especially around delimiters and special tokens. When you are starting out with a new format, you should always do the following: - -1. Materialize some data using `python -m axolotl.cli.preprocess your_config.yml --debug`, and then decode the first few rows with your model's tokenizer. -2. During inference, right before you pass a tensor of token ids to your model, decode these tokens back into a string. -3. Make sure the inference string from #2 looks **exactly** like the data you fine tuned on from #1, including spaces and new lines.

Each method has their own dataset format which are described below. + +## [Pre-training](pretraining.qmd) + +When aiming to train on large corpora of text datasets, pre-training is your go-to choice. Due to the size of these datasets, downloading the entire-datasets before beginning training would be prohibitively time-consuming. Axolotl supports [streaming](https://huggingface.co/docs/datasets/en/stream) to only load batches into memory at a time. + +A sample format for a pre-training dataset is as follows: + +```json +{"text": "first row"} +{"text": "second row"} +... +``` + +It is typically recommended to save your dataset as `.jsonl` due to its flexibility and simplicity. + +Axolotl supports loading from a Hugging Face hub repo or from local files. + +::: {.callout-important} +For pre-training only, Axolotl would split texts if it exceeds the context length into multiple smaller prompts. +::: + +### Pre-training from Hugging Face hub datasets + +As an example, to train using a Hugging Face dataset `hf_org/name`, you can pass the following config: + +```yaml +pretraining_dataset: hf_org/name +``` + +### Pre-training from local dataset files + +Given a few corpus files: `A.jsonl`, `B.jsonl`, and `C.jsonl`, your config will look like the below: + +```yaml +pretraining_dataset: + - path: json + data_files: + - A.jsonl + - B.jsonl + - C.jsonl +``` + +While we recommend `.jsonl`, you can also use the other formats (`csv`, `parquet`, `arrow`, `SQL`, `Webdataset`) that are supported by [`Dataset.load_dataset`](https://huggingface.co/docs/datasets/loading#local-and-remote-files) + +### Pre-training without streaming + +On the rare case that the dataset is small and can be loaded entirely into memory, another approach to running pre-training is to use the `completion` format.

Do you already have the dataset tokenized? If yes, check [Pre-Tokenized Dataset](#pre-tokenized-dataset). + +2. Do you want to format the dataset yourself and manually choose each section to mask? If yes, check [Template Free Dataset](#template-free-dataset) + +3. Is your dataset in a "conversation" format, containing a `list[messages]`? If yes, check [Conversation Dataset](#conversation-dataset) + +4. Is your dataset in an "instruct" format, containing `{ instruction, response }`? If yes, check [Instruction Dataset](#instruction-dataset) + +If you went through the flow chart and did not find one that matches, it is recommended to preprocess your dataset into one of the above or create a Github Discussion. + +::: {.callout-tip} +You can mix and match within each approach or across approaches to train a model on a variety of datasets. +::: + +### [Pre-Tokenized Dataset](tokenized.qmd) + +We suggest this approach when you want to bring your own tokenized dataset. + +Axolotl expects the dataset to have three keys: +- `input_ids`: from tokenizing formatted prompt +- `attention_mask`: for masking padding. If you don't add padding, it would be equal to `len(input_ids) * [1]` +- `labels`: this is the same as `input_ids`, however, if you want to mask certain tokens, you would set those indices to `-100`. + +::: {.callout-tip} +Make sure to add BOS/EOS tokens to your prompt and mask it appropriately. +::: + +A config for this would look like: + +```yaml +datasets: + - path: A.jsonl + type: +``` + +::: {.callout-note} +`type: ` is empty! +::: + +### [Template Free Dataset](template_free.qmd) + +We reccomend this approach when you want granular control over the prompt formatting, special tokens, and masking, whilst letting Axolotl handle the tokenization. This is very useful if your dataset has unique prompts that differ across samples and where one single general template wouldn't suffice. + +In the example below, you could see that there is no proper structure. At the same time, it's very flexible as there are no constraints on how your prompt can look. + +```json +{ + "segments": [ + { + "label": true, + "text": "Hello\n" + }, + { + "label": true, + "text": "hi there!. " + }, + { + "label": false, + "text": "goodbye " + }, + { + "label": true, + "text": "farewell" + } + ] +} +``` + +Each prompt must be have a key called `segments` which is a list of `{ text, label }`. + +```yaml +datasets: + - path: A.jsonl + type: input_output +``` + +### [Conversation Dataset](conversation.qmd) + +`conversation` messages are a list of messages which usually contain a `role` and `content` key. + +::: {.callout-tip} +Fun fact: Axolotl synonymously refers to "chat" messages as `conversation` messages due to how FastChat initially used this term to build a widely used [fastchat conversation](https://github.com/lm-sys/FastChat/blob/main/fastchat/conversation.py) method for formatting chat messages prior to the creation of `chat_templates`. +::: + +#### What are `chat_templates`? + +The current most popular and convenient method for inference is to use `chat_templates` for formatting prompts. Axolotl supports using `chat_templates` for training to ensure that the model performs in the same environment as in inference. + +Here's a quick rundown on `chat_template`: A `chat_template` is a Jinja2 template which formats a list of messages into a prompt. + +An example of a prompt formatted into a popular template called ChatML can be seen below: + +Single prompt (pretty-printed): +```json +{ + "messages": [ + { + "role": "user", + "content": "Hi" + }, + { + "role": "assistant", + "content": "How can I help you?" + }, + { + "role": "user", + "content": "Can you add 3+5?" + }, + { + "role": "assistant", + "content": "The answer is 8." + } + ] +} +``` + +The ChatML template is as follows: +```jinja2 +{% if not add_generation_prompt is defined %}{% set add_generation_prompt = false %}{% endif %}{% for message in messages %}{{'<|im_start|>' + message['role'] + '\n' + message['content'] + '<|im_end|>' + '\n'}}{% endfor %}{% if add_generation_prompt %}{{ '<|im_start|>assistant\n' }}{% endif %} +``` + +The above prompt formatted into this template will result in: + +``` +<|im_start|>user +Hi<|im_end|> +<|im_start|>assistant +How can I help you?<|im_end|> +<|im_start|>user +Can you add 3+5?<|im_end|> +<|im_start|>assistant +The answer is 8.<|im_end|> +``` + +By using delimiters (`<|im_start|>` and `<|im_end|>`), a prompt separates different speakers which helps the model identify which portion belongs to whom. + +#### Common Conversation Dataset formats + +Older conversation datasets with the following format are colloquially called `sharegpt` datasets. + +```json +{"conversations": [{"from": "...", "value": "..."}]} +``` + +Newer conversation datasets usually follow the OpenAI format. + +```json +{"messages": [{"role": "...", "content": "..."}]} +``` + +Axolotl supports both as well as allowing customization of any kind of key. + +#### [Chat Template Usage](conversation.qmd#chat_template) + +To properly use this method, it is important to identify three things: + +1. Which `chat_template` would you use? + +2. What are the keys in your dataset, and what are the possible roles? For example, in OpenAI format, the keys would be `messages`, `role`, and `content`, respectively, whereas the possible roles are `system`, `user`, and `assistant`. + +3. What do you want to mask? For instance, only assistant messages, only last message, or nothing. + +##### Choosing a `chat_template` + +There are a lot of `chat_templates` out there. Axolotl supports the common ones: [supported chat templates](https://github.com/axolotl-ai-cloud/axolotl/blob/860609392184cf62a7e0ca676658b170e059ce6c/src/axolotl/utils/chat_templates.py#L17). For example, to use ChatML, it would be `chat_template: chatml`. + +However, it is also possible to use the already configured template within the tokenizer by specifying `chat_template: tokenizer_default`. If you want a fallback (in case some tokenizer does not have it pre-configured), you can do `chat_template: tokenizer_default_fallback_chatml` to fallback to the ChatML template if a tokenizer template was not found. + +One last but powerful approach is to bring your own template. This can be set via: + +```yaml +chat_template_jinja: # your template +``` + +##### Setting `chat_template` dataset keys + +We currently default to OpenAI format for dataset keys, so if that's your current dataset format, there's nothing to do here. + +If your dataset format is different, here are the keys you should check (with their defaults): + +```yaml +datasets: + ... + field_messages: messages + message_field_role: role + message_field_content: content +``` + +In some `chat_templates` (e.g. [Gemma](https://huggingface.co/google/gemma-2b-it/blob/main/tokenizer_config.json#L1507)), the roles are hardcoded to `user` and `assistant`. Consequently, you may find it necessary to map the roles in your dataset to these above. We currently have some defaults that should work for common datasets, but if you get a `KeyError`, it would be necessary to add mapping for your roles. Here is an example of how it would look like: + +```yaml +datasets: + ... + roles: + assistant: + - gpt + - model + user: + - human +``` + +In the example above, all `gpt` and `model` values are converted to `assistant`. All `human` values are converted to `user.` + +##### Handling masking + +The common use case for `chat_template` is for chat messages, therefore, it is common to mask all non-assistant messages. Assistant messages refer to the bot messages that you want the model to learn on. + +To train on all `assistant` messages, you would set the following configs. + +```yaml +datasets: + ... + roles_to_train: ["assistant"] + train_on_eos: "turn" +``` + +The `train_on_eos` config means that it would mask all EOS tokens for turns that aren't assistant-turns. The other options are: `all` and `last` to choose which EOS to train on. + +Perhaps, you want to train on `assistant` and `narrator` roles, you can simply add `narrator` to the list of `roles_to_train`. You would also need to add it to the mapping of `roles` above. + +```yaml +datasets: + ... + roles_to_train: ["assistant", "narrator"] + roles: + assistant: + - gpt + - model + user: + - human + narrator: ["narrator"] +``` + +#### Applying `chat_template` + +Once all the above steps are completed, you could combine all these configs together to form a bespoke configuration for your custom dataset. The final step would be to correctly set the EOS token in your config: + +```yaml +datasets: + - path: A.jsonl + type: chat_template + + # step 1 + chat_template: chatml + + # step 2 + field_messages: messages + message_field_role: role + message_field_content: content + + roles: + assistant: + - gpt + - model + - assistant + user: + - human + - user + + # step 3 + roles_to_train: ["assistant"] + train_on_eos: "turn" + +special_tokens: + eos_token: <|im_end|> +``` + +If this config were to be applied to the sample dataset above, the output would look as such (which can be retrieved via `axolotl preprocess config.yaml --debug`): + +``` +<|im_start|>(-100, 128256) user(-100, 882) +(-100, 198) Hi(-100, 13347) <|im_end|>(-100, 128257) +(-100, 198) <|im_start|>(-100, 128256) assistant(-100, 78191) +(-100, 198) How(4438, 4438) can(649, 649) I(358, 358) help(1520, 1520) you(499, 499) ?(30, 30) <|im_end|>(128257, 128257) +(-100, 198) <|im_start|>(-100, 128256) user(-100, 882) +(-100, 198) Can(-100, 6854) you(-100, 499) add(-100, 923) (-100, 220) 3(-100, 18) +(-100, 10) 5(-100, 20) ?(-100, 30) <|im_end|>(-100, 128257) +(-100, 198) <|im_start|>(-100, 128256) assistant(-100, 78191) +(-100, 198) The(791, 791) answer(4320, 4320) is(374, 374) (220, 220) 8(23, 23) .(13, 13) <|im_end|>(128257, 128257) +(-100, 198) +``` + +The first number refers to the label, the second refers to the `token_id`. For example, `-100` labels appear on non-assistant portions, meaning that they are masked during. For assistant portions, the label is the same as the `token_id`. + +### [Instruction Dataset](inst_tune.qmd) + +Instruction datasets are used to train instruction-following models and comprise a prompt, containing an instruction, and a single response. In contrast to chat datasets which may be multi-turn, instruct datasets are typically single-turn. + +An example is of a common format called Alpaca: +```json +{"instruction": "...", "input": "...", "output": "..."} +``` + +Using those keys, a prompt can be built based on it. +``` +Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request. + +### Instruction: +{instruction} + +### Input: +{input} + +### Response: +{output} +``` + +This can be configured as such: +```yaml +datasets: + - path: A.jsonl + type: alpaca +``` + +Axolotl supports many kinds of instruction dataset. All of them can be found here (https://axolotl-ai-cloud.github.io/axolotl/docs/dataset-formats/inst_tune.html) with their respective type and sample row format. + +#### Custom Instruct Prompt Format + +Due to the myriad possibilities of instruction formats, Axolotl allows customizing your own instruction format without having to dive into the code directly. + +In the example below, a sample row is used to output in `mistral_v1` format. +```json +{"input": "...", "output": "..."} +``` + +```yaml +datasets: + - path: repo + type: + system_prompt: "" + + field_system: + field_instruction: input + field_input: + field_output: output + + # multi-line example with input + format: |- + [INST] {instruction} {input} [/INST] + + # single-line example without input + no_input_format: "[INST] {instruction} [/INST]" +``` + +The config sets that the `field_instruction` is actually named `input`, and the `field_input` is empty as we don't have an `input` in this sample. Generally, `instruction` can be thought as the question to the model, and `input` as the additional information with `output` being the response. It is not necessary to have an `input` nor `system`. In the end, the most important part is to understand what format you want it to look like and how you can customize this to your use case. + +## Reinforcement Learning from Human Feedback (RLHF) + +As there are multiple RLHF methods with their own dataset requirements.

+ +## Usage + +These optimizations can be enabled in your Axolotl config YAML file. The +`lora_mlp_kernel` option enables the optimized MLP path, while `lora_qkv_kernel` and +`lora_o_kernel` enable the fused query-key-value projection and optimized output +projection, respectively. + +```yaml +lora_mlp_kernel: true +lora_qkv_kernel: true +lora_o_kernel: true +``` + +## Requirements + +- One or more NVIDIA or AMD GPUs (in order to use the Triton kernels) + - AMD can be used with experimental Triton support by setting the environment variable `TORCH_ROCM_AOTRITON_ENABLE_EXPERIMENTAL=1` +- Targeted LoRA adapters cannot use Dropout + - This may limit model expressivity / cause overfitting +- Targeted LoRA adapters cannot have bias terms + - This may limit model expressivity + +Models with pre-existing LoRA adapters that use Dropout or have bias terms may need to +be re-finetuned without these features in order to be useful. + +## Implementation details + +### Custom autograd functions + +The LoRA MLP autograd function optimizes the entire MLP computation path. It fuses the +LoRA and base weight computations together and provides a single, efficient backward +pass for the entire MLP block. + +For attention components, similar optimizations are provided through a function that +handles the query, key, and value projections, and a function that handles the output +projection. They are designed to work with the existing `transformers` attention +implementation via some monkey-patching logic. + +### Triton kernels + +Two activation functions (SwiGLU and GeGLU) are implemented with Triton kernels for +improved speed and memory performance. These kernels handle both the forward and +backward passes. + +### Integration + +The custom autograd functions and Triton kernels are designed to work together. The +autograd function manages the high-level computation flow and gradient tracking, while +calling the Triton kernels for the activation function computation. During the backward +pass, the kernel computes both the activation output and the required gradients, which +the autograd function then uses to compute the final gradients for the entire +computation path. + +## Future Work + +- Support for additional model architectures +- Support for the FSDP setting +- Support for dropout and bias +- Additional operator fusions diff --git a/examples/llama-3/lora-1b-kernels.yml b/examples/llama-3/lora-1b-kernels.yml new file mode 100644 index 0000000000..9c47f266f1 --- /dev/null +++ b/examples/llama-3/lora-1b-kernels.yml @@ -0,0 +1,82 @@ +base_model: NousResearch/Llama-3.2-1B +# Automatically upload checkpoint and final model to HF +# hub_model_id: username/custom_model_name + +load_in_8bit: false +load_in_4bit: false +strict: false + +datasets: + -

2025 03:39:24 -0500 Subject: [PATCH 0426/1405] chore: cleanup deprecated config elements (#2309) * feat: update metadata fields and refactor config class in axolotlinputconfig - Replace `metadata` fields with `json_schema_extra` in RayConfig class. - Replace `Config` class with `ConfigDict` in AxolotlInputConfig. - Set `populate_by_name` to `True` directly in `ConfigDict` instance. * feat: update axolotlinputconfig in utils * Replace `conlist` with `Annotated` for `datasets`, `test_datasets`, and `pretraining_dataset` fields * Change default values for `lr_scheduler` and `optimizer` fields in `HyperparametersConfig` class * Remove unnecessary Union from `evals_per_epoch` field in `AxolotlInputConfig` class * Import `MinLen` from `annotated_types` module * Remove import of `conlist` from `pydantic` module * feat: update modelinputconfig and axolotlinputconfig in v0_4_1 - Removed ConfigDict import from pydantic in `src/axolotl/utils/config/models/input/v0_4_1/__init__.py` - Added `model_config` with `protected_namespaces` to ModelInputConfig - Replaced `config: ConfigDict` with `model_config` in

0492/1405] hf offline decorator for tests to workaround rate limits (#2452) [skip ci] * hf offline decorator for tests to workaround rate limits * fail quicker so we can see logs * try new cache name * limit files downloaded * phi mini predownload * offline decorator for phi tokenizer * handle meta llama 8b offline too * make sure to return fixtures if they are wrapped too * more fixes * more things offline * more offline things * fix the env var * fix the model name * handle gemma also * force reload of modules to recheck offline status * prefetch mistral too * use reset_sessions so hub picks up offline mode * more fixes * rename so it doesn't seem like a context manager * fix backoff * switch out tinyshakespeare dataset since it runs a py script to fetch data and doesn't work offline * include additional dataset * more fixes * more fixes * replace tiny shakespeaere dataset * skip some tests for now * use more robust check using snapshot download to determine if a dataset name is on the hub * typo for skip reason * use local_files_only * more fixtures * remove local only * use tiny shakespeare as pretrain dataset and streaming can't be offline even if precached * make sure fixtures aren't offline improve the offline reset try bumping version of datasets reorder reloading and setting prime a new cache run the tests now with fresh cache try with a static cache * now run all the ci again with hopefully a correct cache * skip wonky tests for now * skip wonky tests for now * handle offline mode for model card creation --- .github/workflows/tests.yml | 4 +-

The below example shows for a JSON file: + +```yaml +datasets: + - path: /path/to/your/file.jsonl + ds_type: json +``` + +This works for CSV, JSON, Parquet, and Arrow files. + +::: {.callout-tip} + +If `path` points to a file and `ds_type` is not specified, we will automatically infer the dataset type from the file extension, so you could omit `ds_type` if you'd like. + +::: + +#### Directory + +If you're loading a directory, you can point the `path` to the directory. + +Then, you have two options: + +##### Loading entire directory + +You do not need any additional configs. + +We will attempt to load in the following order: +- datasets saved with `datasets.save_to_disk` +- loading entire directory of files (such as with parquet/arrow files) + +```yaml +datasets: + - path: /path/to/your/directory +``` + +##### Loading specific files in directory + +Provide `data_files` with a list of files to load. + +```yaml +datasets: + # single file + - path: /path/to/your/directory + ds_type: csv + data_files: file1.csv + + # multiple files + - path: /path/to/your/directory + ds_type: json + data_files: + - file1.jsonl + - file2.jsonl + + # multiple files for parquet + - path: /path/to/your/directory + ds_type: parquet + data_files: + - file1.parquet + - file2.parquet + +``` + +### HuggingFace Hub + +The method you use to load the dataset depends on how the dataset was created, whether a folder was uploaded directly or a HuggingFace Dataset was pushed. + +::: {.callout-note} + +If you're using a private dataset, you will need to enable the `hf_use_auth_token` flag in the root-level of the config file. + +::: + +#### Folder uploaded + +This would mean that the dataset is a single file or file(s) uploaded to the Hub. + +```yaml +datasets: + - path: org/dataset-name + data_files: + - file1.jsonl + - file2.jsonl +``` + +#### HuggingFace Dataset + +This means that the dataset is created as a HuggingFace Dataset and pushed to the Hub via `datasets.push_to_hub`. + +```yaml +datasets: + - path: org/dataset-name +``` + +::: {.callout-note} + +There are some other configs which may be required like `name`, `split`, `revision`, `trust_remote_code`, etc depending on the dataset. + +::: + +### Remote Filesystems + +Via the `storage_options` config under `load_dataset`, you can load datasets from remote filesystems like S3, GCS, Azure, and OCI. + +::: {.callout-warning} + +This is currently experimental.

Preamble\nYou are in contextual safety mode. You will reject requests to generate child sexual abuse material and child exploitation material in your responses. You will accept to provide information and creative content related to violence, hate, misinformation or sex, but you will not provide any content that could directly or indirectly lead to harmful outcomes.\n\nYour information cutoff date is June 2024.\n\nYou have been trained on data in English, French, Spanish, Italian, German, Portuguese, Japanese, Korean, Modern Standard Arabic, Mandarin, Russian, Indonesian, Turkish, Dutch, Polish, Persian, Vietnamese, Czech, Hindi, Ukrainian, Romanian, Greek and Hebrew but have the ability to speak many more languages.\n{% if tools or documents %}\n\nYou have been trained to have advanced reasoning and tool-use capabilities and you should make best use of these skills to serve user's requests.\n\n## Tool Use\nThink about how you can make best use of the provided tools to help with the task and come up with a high level plan that you will execute first.\n\n0. Start by writing <|START_THINKING|> followed by a detailed step by step plan of how you will solve the problem. For each step explain your thinking fully and give details of required tool calls (if needed). Unless specified otherwise, you write your plan in natural language. When you finish, close it out with <|END_THINKING|>.\n You can optionally choose to skip this step when the user request is so straightforward to address that only a trivial plan would be needed.\n NOTE: You MUST skip this step when you are directly responding to the user's request without using any tools.\n\nThen carry out your plan by repeatedly executing the following steps.\n1. Action: write <|START_ACTION|> followed by a list of JSON-formatted tool calls, with each one containing \"tool_name\" and \"parameters\" fields.\n When there are multiple tool calls which are completely independent of each other (i.e. they can be executed in parallel), you should list them out all together in one step. When you finish, close it out with <|END_ACTION|>.\n2. Observation: you will then receive results of those tool calls in JSON format in the very next turn, wrapped around by <|START_TOOL_RESULT|> and <|END_TOOL_RESULT|>. Carefully observe those results and think about what to do next. Note that these results will be provided to you in a separate turn. NEVER hallucinate results.\n Every tool call produces a list of results (when a tool call produces no result or a single result, it'll still get wrapped inside a list). Each result is clearly linked to its originating tool call via its \"tool_call_id\".\n3. Reflection: start the next turn by writing <|START_THINKING|> followed by what you've figured out so far, any changes you need to make to your plan, and what you will do next. When you finish, close it out with <|END_THINKING|>.\n You can optionally choose to skip this step when everything is going according to plan and no special pieces of information or reasoning chains need to be recorded.\n NOTE: You MUST skip this step when you are done with tool-use actions and are ready to respond to the user.\n\nYou can repeat the above 3 steps multiple times (could be 0 times too if no suitable tool calls are available or needed), until you decide it's time to finally respond to the user.\n\n4. Response: then break out of the loop and write <|START_RESPONSE|> followed by a piece of text which serves as a response to the user's last request. Use all previous tool calls and results to help you when formulating your response. When you finish, close it out with <|END_RESPONSE|>.\n{% if enable_citations %}\n\n## Grounding\nImportantly, note that \"Reflection\" and \"Response\" above can be grounded.\nGrounding means you associate pieces of texts (called \"spans\") with those specific tool results that support them (called \"sources\"). And you use a pair of tags \"\" and \"\" to indicate when a span can be grounded onto a list of sources, listing them out in the closing tag. Sources from the same tool call are grouped together and listed as \"{tool_call_id}:[{list of result indices}]\", before they are joined together by \",\". E.g., \"span\" means that \"span\" is supported by result 1 and 2 from \"tool_call_id=0\" as well as result 0 from \"tool_call_id=1\".\n{% endif %}\n\n## Available Tools\nHere is the list of tools that you have available to you.\nYou can ONLY use the tools listed here.

When you finish, close it out with <|END_THINKING|>.\n You can optionally choose to skip this step when the user request is so straightforward to address that only a trivial plan would be needed.\n NOTE: You MUST skip this step when you are directly responding to the user's request without using any tools.\n\nThen carry out your plan by repeatedly executing the following steps.\n1. Action: write <|START_ACTION|> followed by a list of JSON-formatted tool calls, with each one containing \"tool_name\" and \"parameters\" fields.\n When there are multiple tool calls which are completely independent of each other (i.e. they can be executed in parallel), you should list them out all together in one step. When you finish, close it out with <|END_ACTION|>.\n2. Observation: you will then receive results of those tool calls in JSON format in the very next turn, wrapped around by <|START_TOOL_RESULT|> and <|END_TOOL_RESULT|>. Carefully observe those results and think about what to do next. Note that these results will be provided to you in a separate turn. NEVER hallucinate results.\n Every tool call produces a list of results (when a tool call produces no result or a single result, it'll still get wrapped inside a list). Each result is clearly linked to its originating tool call via its \"tool_call_id\".\n3. Reflection: start the next turn by writing <|START_THINKING|> followed by what you've figured out so far, any changes you need to make to your plan, and what you will do next. When you finish, close it out with <|END_THINKING|>.\n You can optionally choose to skip this step when everything is going according to plan and no special pieces of information or reasoning chains need to be recorded.\n NOTE: You MUST skip this step when you are done with tool-use actions and are ready to respond to the user.\n\nYou can repeat the above 3 steps multiple times (could be 0 times too if no suitable tool calls are available or needed), until you decide it's time to finally respond to the user.\n\n4. Response: then break out of the loop and write <|START_RESPONSE|> followed by a piece of text which serves as a response to the user's last request. Use all previous tool calls and results to help you when formulating your response. When you finish, close it out with <|END_RESPONSE|>.\n{% if enable_citations %}\n\n## Grounding\nImportantly, note that \"Reflection\" and \"Response\" above can be grounded.\nGrounding means you associate pieces of texts (called \"spans\") with those specific tool results that support them (called \"sources\"). And you use a pair of tags \"\" and \"\" to indicate when a span can be grounded onto a list of sources, listing them out in the closing tag. Sources from the same tool call are grouped together and listed as \"{tool_call_id}:[{list of result indices}]\", before they are joined together by \",\". E.g., \"span\" means that \"span\" is supported by result 1 and 2 from \"tool_call_id=0\" as well as result 0 from \"tool_call_id=1\".\n{% endif %}\n\n## Available Tools\nHere is the list of tools that you have available to you.\nYou can ONLY use the tools listed here.

Response: then break out of the loop and write <|START_RESPONSE|> followed by a piece of text which serves as a response to the user's last request.

Start by writing <|START_THINKING|> followed by a detailed step by step plan of how you will solve the problem. For each step explain your thinking fully and give details of required tool calls (if needed). Unless specified otherwise, you write your plan in natural language. When you finish, close it out with <|END_THINKING|>.\n You can optionally choose to skip this step when the user request is so straightforward to address that only a trivial plan would be needed.\n NOTE: You MUST skip this step when you are directly responding to the user's request without using any tools.\n\nThen carry out your plan by repeatedly executing the following steps.\n1. Action: write <|START_ACTION|> followed by a list of JSON-formatted tool calls, with each one containing \"tool_name\" and \"parameters\" fields.\n When there are multiple tool calls which are completely independent of each other (i.e. they can be executed in parallel), you should list them out all together in one step. When you finish, close it out with <|END_ACTION|>.\n2. Observation: you will then receive results of those tool calls in JSON format in the very next turn, wrapped around by <|START_TOOL_RESULT|> and <|END_TOOL_RESULT|>. Carefully observe those results and think about what to do next. Note that these results will be provided to you in a separate turn. NEVER hallucinate results.\n Every tool call produces a list of results (when a tool call produces no result or a single result, it'll still get wrapped inside a list). Each result is clearly linked to its originating tool call via its \"tool_call_id\".\n3. Reflection: start the next turn by writing <|START_THINKING|> followed by what you've figured out so far, any changes you need to make to your plan, and what you will do next. When you finish, close it out with <|END_THINKING|>.\n You can optionally choose to skip this step when everything is going according to plan and no special pieces of information or reasoning chains need to be recorded.\n NOTE: You MUST skip this step when you are done with tool-use actions and are ready to respond to the user.\n\nYou can repeat the above 3 steps multiple times (could be 0 times too if no suitable tool calls are available or needed), until you decide it's time to finally respond to the user.\n\n4. Response: then break out of the loop and write <|START_RESPONSE|> followed by a piece of text which serves as a response to the user's last request. Use all previous tool calls and results to help you when formulating your response. When you finish, close it out with <|END_RESPONSE|>.\n{% if enable_citations %}\n\n## Grounding\nImportantly, note that \"Reflection\" and \"Response\" above can be grounded.\nGrounding means you associate pieces of texts (called \"spans\") with those specific tool results that support them (called \"sources\").

Sources from the same tool call are grouped together and listed as \"{tool_call_id}:[{list of result indices}]\", before they are joined together by \",\".

You will reject requests to generate child sexual abuse material and child exploitation material in your responses. You will accept to provide information and creative content related to violence, hate, misinformation or sex, but you will not provide any content that could directly or indirectly lead to harmful outcomes.\n\nYour information cutoff date is June 2024.\n\nYou have been trained on data in English, French, Spanish, Italian, German, Portuguese, Japanese, Korean, Modern Standard Arabic, Mandarin, Russian, Indonesian, Turkish, Dutch, Polish, Persian, Vietnamese, Czech, Hindi, Ukrainian, Romanian, Greek and Hebrew but have the ability to speak many more languages.\n{% if tools or documents %}\n\nYou have been trained to have advanced reasoning and tool-use capabilities and you should make best use of these skills to serve user\'s requests.\n\n## Tool Use\nThink about how you can make best use of the provided tools to help with the task and come up with a high level plan that you will execute first.\n\n0. Start by writing <|START_THINKING|> followed by a detailed step by step plan of how you will solve the problem. For each step explain your thinking fully and give details of required tool calls (if needed). Unless specified otherwise, you write your plan in natural language. When you finish, close it out with <|END_THINKING|>.\n You can optionally choose to skip this step when the user request is so straightforward to address that only a trivial plan would be needed.\n NOTE: You MUST skip this step when you are directly responding to the user\'s request without using any tools.\n\nThen carry out your plan by repeatedly executing the following steps.\n1. Action: write <|START_ACTION|> followed by a list of JSON-formatted tool calls, with each one containing "tool_name" and "parameters" fields.\n When there are multiple tool calls which are completely independent of each other (i.e. they can be executed in parallel), you should list them out all together in one step. When you finish, close it out with <|END_ACTION|>.\n2. Observation: you will then receive results of those tool calls in JSON format in the very next turn, wrapped around by <|START_TOOL_RESULT|> and <|END_TOOL_RESULT|>. Carefully observe those results and think about what to do next. Note that these results will be provided to you in a separate turn. NEVER hallucinate results.\n Every tool call produces a list of results (when a tool call produces no result or a single result, it\'ll still get wrapped inside a list). Each result is clearly linked to its originating tool call via its "tool_call_id".\n3. Reflection: start the next turn by writing <|START_THINKING|> followed by what you\'ve figured out so far, any changes you need to make to your plan, and what you will do next. When you finish, close it out with <|END_THINKING|>.\n You can optionally choose to skip this step when everything is going according to plan and no special pieces of information or reasoning chains need to be recorded.\n NOTE: You MUST skip this step when you are done with tool-use actions and are ready to respond to the user.\n\nYou can repeat the above 3 steps multiple times (could be 0 times too if no suitable tool calls are available or needed), until you decide it\'s time to finally respond to the user.\n\n4. Response: then break out of the loop and write <|START_RESPONSE|> followed by a piece of text which serves as a response to the user\'s last request. Use all previous tool calls and results to help you when formulating your response. When you finish, close it out with <|END_RESPONSE|>.\n{% if enable_citations %}\n\n## Grounding\nImportantly, note that "Reflection" and "Response" above can be grounded.\nGrounding means you associate pieces of texts (called "spans") with those specific tool results that support them (called "sources"). And you use a pair of tags "" and "" to indicate when a span can be grounded onto a list of sources, listing them out in the closing tag. Sources from the same tool call are grouped together and listed as "{tool_call_id}:[{list of result indices}]", before they are joined together by ",". E.g., "span" means that "span" is supported by result 1 and 2 from "tool_call_id=0" as well as result 0 from "tool_call_id=1".\n{% endif %}\n\n## Available Tools\nHere is the list of tools that you have available to you.\nYou can ONLY use the tools listed here.

Start by writing <|START_THINKING|> followed by a detailed step by step plan of how you will solve the problem. For each step explain your thinking fully and give details of required tool calls (if needed). Unless specified otherwise, you write your plan in natural language. When you finish, close it out with <|END_THINKING|>.\n You can optionally choose to skip this step when the user request is so straightforward to address that only a trivial plan would be needed.\n NOTE: You MUST skip this step when you are directly responding to the user\'s request without using any tools.\n\nThen carry out your plan by repeatedly executing the following steps.\n1. Action: write <|START_ACTION|> followed by a list of JSON-formatted tool calls, with each one containing "tool_name" and "parameters" fields.\n When there are multiple tool calls which are completely independent of each other (i.e. they can be executed in parallel), you should list them out all together in one step. When you finish, close it out with <|END_ACTION|>.\n2. Observation: you will then receive results of those tool calls in JSON format in the very next turn, wrapped around by <|START_TOOL_RESULT|> and <|END_TOOL_RESULT|>. Carefully observe those results and think about what to do next. Note that these results will be provided to you in a separate turn. NEVER hallucinate results.\n Every tool call produces a list of results (when a tool call produces no result or a single result, it\'ll still get wrapped inside a list). Each result is clearly linked to its originating tool call via its "tool_call_id".\n3. Reflection: start the next turn by writing <|START_THINKING|> followed by what you\'ve figured out so far, any changes you need to make to your plan, and what you will do next. When you finish, close it out with <|END_THINKING|>.\n You can optionally choose to skip this step when everything is going according to plan and no special pieces of information or reasoning chains need to be recorded.\n NOTE: You MUST skip this step when you are done with tool-use actions and are ready to respond to the user.\n\nYou can repeat the above 3 steps multiple times (could be 0 times too if no suitable tool calls are available or needed), until you decide it\'s time to finally respond to the user.\n\n4. Response: then break out of the loop and write <|START_RESPONSE|> followed by a piece of text which serves as a response to the user\'s last request. Use all previous tool calls and results to help you when formulating your response.

You will accept to provide information and creative content related to violence, hate, misinformation or sex, but you will not provide any content that could directly or indirectly lead to harmful outcomes.\n\nYour information cutoff date is June 2024.\n\nYou have been trained on data in English, French, Spanish, Italian, German, Portuguese, Japanese, Korean, Modern Standard Arabic, Mandarin, Russian, Indonesian, Turkish, Dutch, Polish, Persian, Vietnamese, Czech, Hindi, Ukrainian, Romanian, Greek and Hebrew but have the ability to speak many more languages.\n{% if tools or documents %}\n\nYou have been trained to have advanced reasoning and tool-use capabilities and you should make best use of these skills to serve user\'s requests.\n\n## Tool Use\nThink about how you can make best use of the provided tools to help with the task and come up with a high level plan that you will execute first.\n\n0. Start by writing <|START_THINKING|> followed by a detailed step by step plan of how you will solve the problem. For each step explain your thinking fully and give details of required tool calls (if needed). Unless specified otherwise, you write your plan in natural language. When you finish, close it out with <|END_THINKING|>.\n You can optionally choose to skip this step when the user request is so straightforward to address that only a trivial plan would be needed.\n NOTE: You MUST skip this step when you are directly responding to the user\'s request without using any tools.\n\nThen carry out your plan by repeatedly executing the following steps.\n1. Action: write <|START_ACTION|> followed by a list of JSON-formatted tool calls, with each one containing "tool_name" and "parameters" fields.\n When there are multiple tool calls which are completely independent of each other (i.e. they can be executed in parallel), you should list them out all together in one step. When you finish, close it out with <|END_ACTION|>.\n2. Observation: you will then receive results of those tool calls in JSON format in the very next turn, wrapped around by <|START_TOOL_RESULT|> and <|END_TOOL_RESULT|>. Carefully observe those results and think about what to do next. Note that these results will be provided to you in a separate turn. NEVER hallucinate results.\n Every tool call produces a list of results (when a tool call produces no result or a single result, it\'ll still get wrapped inside a list). Each result is clearly linked to its originating tool call via its "tool_call_id".\n3. Reflection: start the next turn by writing <|START_THINKING|> followed by what you\'ve figured out so far, any changes you need to make to your plan, and what you will do next. When you finish, close it out with <|END_THINKING|>.\n You can optionally choose to skip this step when everything is going according to plan and no special pieces of information or reasoning chains need to be recorded.\n NOTE: You MUST skip this step when you are done with tool-use actions and are ready to respond to the user.\n\nYou can repeat the above 3 steps multiple times (could be 0 times too if no suitable tool calls are available or needed), until you decide it\'s time to finally respond to the user.\n\n4. Response: then break out of the loop and write <|START_RESPONSE|> followed by a piece of text which serves as a response to the user\'s last request. Use all previous tool calls and results to help you when formulating your response. When you finish, close it out with <|END_RESPONSE|>.\n{% if enable_citations %}\n\n## Grounding\nImportantly, note that "Reflection" and "Response" above can be grounded.\nGrounding means you associate pieces of texts (called "spans") with those specific tool results that support them (called "sources"). And you use a pair of tags "" and "" to indicate when a span can be grounded onto a list of sources, listing them out in the closing tag. Sources from the same tool call are grouped together and listed as "{tool_call_id}:[{list of result indices}]", before they are joined together by ",". E.g., "span" means that "span" is supported by result 1 and 2 from "tool_call_id=0" as well as result 0 from "tool_call_id=1".\n{% endif %}\n\n## Available Tools\nHere is the list of tools that you have available to you.\nYou can ONLY use the tools listed here.

Action: write <|START_ACTION|> followed by a list of JSON-formatted tool calls, with each one containing "tool_name" and "parameters" fields. + When there are multiple tool calls which are completely independent of each other (i.e. they can be executed in parallel), you should list them out all together in one step. When you finish, close it out with <|END_ACTION|>. +2. Observation: you will then receive results of those tool calls in JSON format in the very next turn, wrapped around by <|START_TOOL_RESULT|> and <|END_TOOL_RESULT|>. Carefully observe those results and think about what to do next. Note that these results will be provided to you in a separate turn. NEVER hallucinate results. + Every tool call produces a list of results (when a tool call produces no result or a single result, it'll still get wrapped inside a list). Each result is clearly linked to its originating tool call via its "tool_call_id". +3. Reflection: start the next turn by writing <|START_THINKING|> followed by what you've figured out so far, any changes you need to make to your plan, and what you will do next. When you finish, close it out with <|END_THINKING|>. + You can optionally choose to skip this step when everything is going according to plan and no special pieces of information or reasoning chains need to be recorded. + NOTE: You MUST skip this step when you are done with tool-use actions and are ready to respond to the user. + +You can repeat the above 3 steps multiple times (could be 0 times too if no suitable tool calls are available or needed), until you decide it's time to finally respond to the user. + +4. Response: then break out of the loop and write <|START_RESPONSE|> followed by a piece of text which serves as a response to the user's last request.

This is essential when: + +- A model's weights are too large to fit on a single GPU's memory. +- A model's activations, especially with very long contexts, are too large for a single GPU. +- You want to accelerate training by using multiple GPUs or nodes. + +or combinations of the above! + +## Core Concepts + +Parallelism strategies can be combined. The key is understanding how each one divides the workload. PyTorch's `DeviceMesh` is the modern way to manage these combinations, creating a logical grid of your GPUs and assigning different parallel strategies to different dimensions of the grid. + +### Data Parallelism {#sec-dp} + +Data Parallelism focuses on splitting the global data batch across GPUs. + +- Distributed Data Parallel (DDP): The classic approach. The full model is replicated on every GPU. Each GPU processes a different slice of the data batch. Gradients are then averaged across all GPUs after the backward pass to keep the models synchronized. This can substantially improve data throughput compared to single-device training, but requires that each GPU is able to hold the entire model, its gradients, and optimizer states. + +- [Fully Sharded Data Parallel (FSDP)](multi-gpu.qmd#fully-sharded-data-parallel-(fsdp)): A highly memory-efficient form of data parallelism (inspired by DeepSpeed's ZeRO). Instead of replicating the model, FSDP shards the model's *parameters, gradients, and optimizer states* across the GPUs in the data-parallel group. During computation, each GPU receives the specific parameters it needs via an `all_gather` operation just before they are used, and they can be discarded immediately after (`reshard-after-forward`). + - FSDP maps to ZeRO stages: + - ZeRO-2 (`reshard_after_forward=False`): Shards gradients and optimizer states. Model weights are replicated on each GPU. + - ZeRO-3 (`reshard_after_forward=True`): Shards gradients, optimizer states, AND model parameters. This provides the most memory savings at the cost of more communication (re-gathering parameters for both forward and backward passes). + +### [Experimental] Tensor Parallelism (TP) {#sec-tp} + +Also known as "horizontal model parallelism," as described in the [Megatron-LM paper](https://arxiv.org/pdf/1909.08053.pdf). Instead of splitting the batch, TP splits the model's layers themselves across GPUs. + +- How it works: For a linear layer `Y = XA`, the weight matrix `A` is split column-wise (`A = [A_1, A_2]`). The computation becomes `Y_1 = XA_1` and `Y_2 = XA_2`, which can happen in parallel on different GPUs. The final output `Y` is simply the concatenation of `Y_1` and `Y_2`. Check [this comment](https://github.com/huggingface/transformers/issues/10321#issuecomment-783543530) for more detailed info. +- Requirement: TP involves frequent, small communications within a forward/backward pass. It requires a very fast interconnect between GPUs (e.g., NVLink) and is typically not recommended across different nodes. + +### Context Parallelism (CP) {#sec-cp} + +Context Parallelism, also called [Sequence Parallelism](sequence_parallelism.qmd), addresses the memory bottleneck from long sequences. The input sequence itself is split along the sequence length dimension and distributed across GPUs. + +- How it works: If you have a sequence of 8192 tokens and a `context_parallel_size` of 4, each GPU will only handle a chunk of 2048 tokens. +- The Challenge: Attention is not local; every token needs to "attend to" every other token. Splitting the sequence breaks this. +- The Solution (`ring-flash-attention`): An efficient communication protocol is used. To compute attention for its local sequence chunk, each GPU passes its Key-Value (KV) cache to its neighbor in a "ring." After `N-1` steps, every GPU has seen the KV-cache from all other GPUs, allowing it to compute the correct attention values for its chunk. This is implemented using the highly optimized `flash-attention` kernel at each step. + +### Hybrid Sharding Data Parallel (HSDP) {#sec-hsdp} + +HSDP is a 2D strategy that intelligently combines FSDP and DDP, typically for multi-node training. + +- Intra-Node (within a machine): Use FSDP. This is efficient because GPUs on the same node have fast interconnects (NVLink), making the `all_gather` operations for sharded parameters fast. +- Inter-Node (across machines): Use DDP. The gradient synchronization between nodes is less frequent than FSDP's parameter gathering, making it a better fit for the slower node-to-node network (e.g., Ethernet/Infiniband). +- Example: With 2 nodes of 8 GPUs each (16 total), you could have `dp_shard_size=8` (FSDP within each node) and `dp_replicate_size=2` (DDP across the two nodes). + +## Usage + +```yaml +# FSDP config. See https://docs.axolotl.ai/docs/multi-gpu.html#sec-fsdp +fsdp_version: 2 +fsdp_config: + # ... + +# The number of GPUs to shard the model parameters across (FSDP dimension). +dp_shard_size: 4 + +# The number of times to replicate the sharded model (DDP dimension). +dp_replicate_size: 2 + +# Number of GPUs for Tensor Parallelism. +tensor_parallel_size: 1 # (default is 1, no TP) + +# Number of GPUs for Context/Sequence Parallelism. +context_parallel_size: 1 # (default is 1, no CP) +``` + +Note: We recommend FSDP. DeepSpeed is only compatible with `tensor_parallel_size`. + +## Examples + +1. HSDP on 2 nodes with 4 GPUs each (8 GPUs total): + - You want FSDP within each node and DDP across nodes. + - Set `dp_shard_size: 4` and `dp_replicate_size: 2`. + +2. FSDP + TP on a single 8-GPU node: + - You want to split the model across 4 GPUs using FSDP, and further split each layer across 2 GPUs with TP. + - Set `dp_shard_size: 4` and `tensor_parallel_size: 2`. + +3. FSDP + CP on a single 8-GPU node for long context: + - You want to shard the model across all 8 GPUs and also split the sequence length across all 8 GPUs. + - Set `dp_shard_size: 8` and `context_parallel_size: 8`. Note: this means the data parallel group and context parallel group are the same. A more common setup might be to shard across a smaller group. + +## Support Matrix + +This matrix describes how different parallelism methods can be combined in Axolotl. + +| Combination | `dp_replicate_size` | `dp_shard_size` | `tp_size` | `cp_size` | Status & Notes | +| --- | :---: | :---: |:---:|:---:|---| +| **FSDP** (ZeRO-3) | 1 | >1 | 1 | 1 | ✅ Fully supported.

The series introduces architectural innovations including Hybrid Attention (Gated DeltaNet + Gated Attention), High-Sparsity MoE with 1:50 activation ratio, and Multi-Token Prediction for enhanced performance and inference acceleration. + +This guide shows how to fine-tune it with Axolotl with multi-turn conversations and proper masking. + +## Getting started + +1. Install Axolotl following the [installation guide](https://docs.axolotl.ai/docs/installation.html). You need to install from main as Qwen3-Next is only on nightly or use our latest [Docker images](https://docs.axolotl.ai/docs/docker.html). + + Here is an example of how to install from main for pip: + +```bash +# Ensure you have Pytorch installed (Pytorch 2.6.0 min) +git clone https://github.com/axolotl-ai-cloud/axolotl.git +cd axolotl + +pip3 install packaging==23.2 setuptools==75.8.0 wheel ninja +pip3 install --no-build-isolation -e '.[flash-attn]' + +# Install CCE https://docs.axolotl.ai/docs/custom_integrations.html#cut-cross-entropy +python scripts/cutcrossentropy_install.py | sh +``` + +2.

Install FLA for improved performance +```bash +pip3 uninstall -y causal-conv1d && pip3 install flash-linear-attention==0.3.2 +``` + +4. Run the finetuning example: + +```bash +axolotl train examples/qwen3-next/qwen3-next-80b-a3b-qlora.yaml +``` + +This config uses about 41.7 GiB VRAM. + +Let us know how it goes. Happy finetuning! 🚀 + +### TIPS + +- For inference, you can experiment with `temperature: 0.7`, `top_p: 0.8`, `top_k: 20`, and `min_p: 0`. +- You can run a full finetuning by removing the `adapter: qlora` and `load_in_4bit: true` from the config.

You can trigger checkpoints via file-based triggers (for programmatic control) or Control+C (for interactive use). + +## File-Based Checkpoint Trigger + +### Configuration + +Enable in your config: + +```yaml +dynamic_checkpoint: + enabled: true + check_interval: 100 # Optional: check every N steps (default: 100) + trigger_file_path: "axolotl_checkpoint.save" # Optional: custom filename +``` + +**Options:** +- `enabled`: `true` to enable (required) +- `check_interval`: Steps between file checks. Default: 100. Lower = faster response, higher I/O overhead. +- `trigger_file_path`: Custom trigger filename. Default: `axolotl_checkpoint.save` + +### How It Works + +1. Rank 0 checks for trigger file every `check_interval` steps in `output_dir` +2. When detected, file is deleted and checkpoint is saved +3. In distributed training, rank 0 broadcasts to synchronize all ranks + +### Usage + +**Command line:** +```bash +touch /path/to/output_dir/axolotl_checkpoint.save +``` + +**Programmatic:** +```python +from pathlib import Path +Path("/path/to/output_dir/axolotl_checkpoint.save").touch() +``` + +Checkpoint saves within the next `check_interval` steps. The trigger file is auto-deleted after detection, so you can create it multiple times. + +**Custom filename:** +```yaml +dynamic_checkpoint: + enabled: true + trigger_file_path: "my_trigger.save" +``` +```bash +touch /path/to/output_dir/my_trigger.save +``` + +## Control+C (SIGINT) Checkpoint + +Pressing `Ctrl+C` during training saves the model state and exits gracefully. **Note:** This saves only the model weights, not optimizer state. For resumable checkpoints, use the file-based trigger. + +## Best Practices + +- **Check interval**: Lower values (10-50) for fast training, default 100 for slower training +- **Distributed training**: Create trigger file once; rank 0 handles synchronization +- **Resume**: Dynamic checkpoints can be resumed like regular checkpoints via `resume_from_checkpoint` + +## Example + +```yaml +output_dir: ./outputs/lora-out +save_steps: 500 # Scheduled checkpoints + +dynamic_checkpoint: + enabled: true + check_interval: 50 +``` + +This enables scheduled checkpoints every 500 steps plus on-demand saves via file trigger (checked every 50 steps).

Jan 2026 17:08:24 -0500 Subject: [PATCH 1105/1405] transformers v5 upgrade (#3272) * Prepare for transformers v5 upgrade * fix hf cli * update for hf hub changes * fix tokenizer apply_chat_template args * remap include_tokens_per_second * fix tps * handle migration for warmup * use latest hf hub * Fix scan -> ls * fix import * fix for renaming of mistral common tokenizer -> backend * update for fixed tokenziation for llama * Skip phi35 tests for now * remove mistral patch fixed upstream in huggingface/transformers#41439 * use namespacing for patch * don't rely on sdist for e2e tests for now * run modal ci without waiting too * Fix dep for ci * fix imports * Fix fp8 check * fsdp2 fixes * fix version handling * update fsdp version tests for new v5 behavior * Fail multigpu tests after 3 failures * skip known v5 broken tests for now and cleanup * bump deps * unmark skipped test * re-enable test_fsdp_qlora_prequant_packed test * increase multigpu ci timeout * skip broken gemma3 test * reduce timout back to original 120min now that the hanging test is skipped * fix for un-necessary collator for pretraining with bsz=1 * fix: safe_serialization deprecated in transformers v5 rc01 (#3318) * torch_dtype deprecated * load model in float32 for consistency with tests * revert some test fixtures back * use hf cache ls instead of scan * don't strip fsdp_version more fdsp_Version fixes for v5 fix version in fsdp_config fix aliasing fix fsdp_version check check fsdp_version is 2 in both places * Transformers v5 rc2 (#3347) * bump dep * use latest fbgemm, grab model config as part of fixture, un-skip test * import AutoConfig * don't need more problematic autoconfig when specifying config.json manually * add fixtures for argilla ultrafeedback datasets * download phi4-reasoning * fix arg * update tests for phi fast tokenizer changes * use explicit model types for gemma3 --------- Co-authored-by: Wing Lian * fix: AutoModelForVision2Seq -> AutoModelForImageTextToText * chore: remove duplicate * fix: attempt fix gemma3 text mode * chore: lint * ga release of v5 * need property setter for name_or_path for mistral tokenizer * vllm not compatible with transformers v5 * setter for chat_template w mistral too --------- Co-authored-by: NanoCode012 Co-authored-by: salman --- .github/workflows/main.yml | 2 +-

Also remove the minimal length filtering from the truncate_long_samples function, and run it separately and before. * fix: refactor and add test truncate for non-input id fields * fix: refactor long seq handling fn * fix: refactor duplicate fn and simplify route * add additional tests and make them work on mac * handle logging exception on empty datasets --------- Co-authored-by: 2ndset bot Co-authored-by: NanoCode012 Co-authored-by: Wing Lian --- src/axolotl/utils/data/utils.py | 225 ++++++++----- src/axolotl/utils/trainer.py | 13 +- tests/test_data.py | 20 +- tests/utils/data/test_utils.py | 545 ++++++++++++++++++++++++++++++++ 4 files changed, 717 insertions(+), 86 deletions(-) create mode 100644 tests/utils/data/test_utils.py diff --git a/src/axolotl/utils/data/utils.py b/src/axolotl/utils/data/utils.py index 319e27f6f4..f2cdcac388 100644 --- a/src/axolotl/utils/data/utils.py +++ b/src/axolotl/utils/data/utils.py @@ -15,7 +15,7 @@ from axolotl.utils.dict import DictDefault from axolotl.utils.logging import get_logger from axolotl.utils.samplers.utils import get_dataset_lengths -from axolotl.utils.trainer import drop_long_seq +from axolotl.utils.trainer import filter_sequences_by_length LOG = get_logger(__name__) @@ -148,22 +148,33 @@ def deduplicate_and_log_datasets( return dataset, other_dataset -def truncate_long_seq(sample, sequence_len=2048, min_sequence_len=2): +def keep_min_len(sample, min_sequence_len=2): """ - Truncate samples whose sequence length is too long (> sequence_len) - or drop those too short (< min_sequence_len). + Batched filter function that keeps only samples with sequence length >= min_sequence_len. + Returns a list of booleans indicating which samples to keep.

This ensures the saved preprocessed dataset is already de-duplicated, so subsequent loads from cache don't contain duplicates. Fixes #2719 * fix: include deduplication flag in dataset hash and warn on skip_prepare_dataset+dedup - Add dataset_exact_deduplication to the hash string in generate_dataset_hash_from_config so cached datasets are invalidated when the dedup setting changes. - Log a warning when skip_prepare_dataset=True and dataset_exact_deduplication=True, since dedup will be silently skipped in that configuration (both SFT and RL paths). * fix: add ValueError for skip_prepare+dedup, fix test mock target and formatting - Add config validator (check_deduplication_with_skip_prepare) that raises ValueError when skip_prepare_dataset=True and dataset_exact_deduplication=True - Replace runtime warnings in sft.py/rl.py with the validator check - Fix RL test: patch axolotl.utils.data.rl.load_tokenizer instead of axolotl.loaders.load_tokenizer to properly mock the imported reference - Fix ruff lint (remove unused imports) and formatting issues * refactor: inline deduplicate function per review feedback * fix test fixture, lint --------- Co-authored-by: ManasVardhan Co-authored-by: Wing Lian --- src/axolotl/utils/data/rl.py | 4 + src/axolotl/utils/data/sft.py | 28 ++-- src/axolotl/utils/data/shared.py | 3 +- src/axolotl/utils/schemas/config.py | 13 ++ tests/test_save_deduplicated.py | 210 ++++++++++++++++++++++++++++ 5 files changed, 237 insertions(+), 21 deletions(-) create mode 100644 tests/test_save_deduplicated.py diff --git a/src/axolotl/utils/data/rl.py b/src/axolotl/utils/data/rl.py index 5ea9e55e01..2c386f35ef 100644 --- a/src/axolotl/utils/data/rl.py +++ b/src/axolotl/utils/data/rl.py @@ -246,6 +246,10 @@ def _load_split(cfg: DictDefault, split: Literal["train", "test"]) -> Dataset: dataset = merge_datasets(split_datasets, cfg) if not cfg.skip_prepare_dataset: + # Deduplicate before saving so the saved dataset is already de-duplicated + if cfg.dataset_exact_deduplication: + dataset, _ = deduplicate_and_log_datasets(dataset=dataset) + # Save preprocessed dataset dataset_hash = generate_dataset_hash_from_config( cfg, datasets_configs, tokenizer.name_or_path diff --git a/src/axolotl/utils/data/sft.py b/src/axolotl/utils/data/sft.py index ba5aec2d60..69cbfb871b 100644 --- a/src/axolotl/utils/data/sft.py +++ b/src/axolotl/utils/data/sft.py @@ -351,6 +351,10 @@ def _load_raw_datasets( if cfg.sample_packing: dataset, _ = process_datasets_for_packing(cfg, dataset, None) + # Deduplicate before saving so the saved dataset is already de-duplicated + if cfg.dataset_exact_deduplication: + dataset, _ = deduplicate_and_log_datasets(dataset=dataset) + # Save the prepared dataset dataset_hash = generate_dataset_hash_from_config( cfg, datasets_configs, tokenizer.name_or_path @@ -438,25 +442,8 @@ def _handle_train_dataset_split( ) return train_dataset, eval_dataset - # No validation split - apply deduplication if needed and return as train dataset - if cfg.dataset_exact_deduplication: - train_dataset, _ = deduplicate_and_log_datasets(dataset=dataset) - else: - train_dataset = dataset - - return train_dataset, None - - -def _handle_test_dataset_split( - dataset: Dataset, cfg: DictDefault -) -> tuple[None, Dataset | None]: - """Handle processing for test split.""" - if cfg.dataset_exact_deduplication: - eval_dataset, _ = deduplicate_and_log_datasets(dataset=dataset) - else: - eval_dataset = dataset - - return None, eval_dataset + # No validation split - deduplication already applied during preprocessing + return dataset, None def _apply_dataset_sharding(dataset: Dataset, cfg: DictDefault) -> Dataset: @@ -515,6 +502,7 @@ def _load_and_prepare_datasets( if split == "train": train_dataset, eval_dataset = _handle_train_dataset_split(dataset, cfg) else: - train_dataset, eval_dataset = _handle_test_dataset_split(dataset, cfg) + # Deduplication already applied during preprocessing + train_dataset, eval_dataset = None, dataset return train_dataset, eval_dataset, prompters diff --git a/src/axolotl/utils/data/shared.py b/src/axolotl/utils/data/shared.py index a8ed55ae2f..351669ec3f 100644 --- a/src/axolotl/utils/data/shared.py +++ b/src/axolotl/utils/data/shared.py @@ -520,7 +520,8 @@ def generate_dataset_hash_from_config( """ config_str = ( f"{cfg.sequence_len}@{cfg.sample_packing}@{cfg.eval_sample_packing}@" - f"{cfg.group_by_length}@{cfg.kd_temperature or 1.0}|" + f"{cfg.group_by_length}@{cfg.kd_temperature or 1.0}@" + f"{cfg.dataset_exact_deduplication or False}|" f"{'|'.join(sorted([f'{d.path}:{d.type}:{d.shards}:{d.conversation}:{d.split}:{d.temperature or 1.0}' for d in cfg_datasets]))}" f"|{tokenizer_name}" ) diff --git a/src/axolotl/utils/schemas/config.py b/src/axolotl/utils/schemas/config.py index 35b4a69081..b15b99955b 100644 --- a/src/axolotl/utils/schemas/config.py +++ b/src/axolotl/utils/schemas/config.py @@ -1509,3 +1509,16 @@ def check_deduplication_with_streaming(cls, data): "dataset_exact_deduplication is not available for streaming datasets.

To apply LoRA to them, add to `lora_target_modules`: -2. Install [Cut Cross Entropy](https://docs.axolotl.ai/docs/custom_integrations.html#cut-cross-entropy) to reduce training VRAM usage. - -3. Install FLA for sample packing support with the Gated DeltaNet linear attention layers: -```bash -pip3 uninstall -y causal-conv1d && pip3 install flash-linear-attention==0.4.1 +```yaml +lora_target_modules: + # ... standard projections ... + - linear_attn.in_proj_qkv + - linear_attn.in_proj_z + - linear_attn.out_proj ``` -> FLA is required when `sample_packing: true`. Without it, training raises a `RuntimeError` on packed sequences. Vision configs use `sample_packing: false` so FLA is optional there. - -4. Run a finetuning example: -```bash -# Dense 27B text-only (QLoRA, ~47 GiB VRAM with sample packing) -axolotl train examples/qwen3.5/27b-qlora.yaml +### Routed Experts (MoE) -# Dense 27B text-only FFT with vision encoder frozen (~53 GiB, single 80 GiB GPU) -axolotl train examples/qwen3.5/27b-fft.yaml +To apply LoRA to routed expert parameters, add `lora_target_parameters`: -# MoE 35B-A3B text-only (QLoRA) -axolotl train examples/qwen3.5/35b-a3b-moe-qlora.yaml - -# MoE 122B-A10B text-only (QLoRA) -axolotl train examples/qwen3.5/122b-a10b-moe-qlora.yaml +```yaml +lora_target_parameters: + - mlp.experts.gate_up_proj + - mlp.experts.down_proj +# - mlp.gate.weight # router +``` -# 9B vision+text (LoRA, multimodal dataset) -axolotl train examples/qwen3.5/9b-lora-vision.yaml +### Shared Experts (MoE) -# 9B vision+text FFT, single 80 GiB GPU (~61 GiB peak) -axolotl train examples/qwen3.5/9b-fft-vision.yaml +Routed experts and shared experts both have `gate_up_proj`/`down_proj`, so a plain module name in `lora_target_modules` would match both. Use a regex to target only attention and shared expert projections, while `lora_target_parameters` above handles routed experts separately: +```yaml +lora_target_modules: 'model\.(language_model\.)?layers\.[\d]+\.(mlp|self_attn)\.(shared_expert\.)?(up|down|gate|gate_up|q|k|v|o)_proj' ``` ### TIPS -- For inference, you can experiment with `temperature: 0.7`, `top_p: 0.8`, `top_k: 20`, and `min_p: 0`. -- For **text-only FFT** on 27B, use `27b-fft.yaml` which sets `unfrozen_parameters` to freeze the vision encoder (`model.visual.*`) — this avoids wasting optimizer state on parameters that receive no gradient from text-only data. +- For inference hyp, please see the respective model card details. - You can run a full finetuning of smaller configs by removing `adapter: qlora` and `load_in_4bit: true`. See [Multi-GPU](#optimization-guides) below. - Read more on loading your own dataset at [docs](https://docs.axolotl.ai/docs/dataset_loading.html). - The dataset format follows the OpenAI Messages format as seen [here](https://docs.axolotl.ai/docs/dataset-formats/conversation.html#chat_template). - For **multimodal** finetuning, set `processor_type: AutoProcessor`, `skip_prepare_dataset: true`, and `remove_unused_columns: false` as shown in `9b-lora-vision.yaml`. -- The Gated DeltaNet linear attention layers (`linear_attn.*`) can optionally be added to `lora_target_modules` — they are commented out by default. ## Optimization Guides From 7ddfb2d8a0531122649a30a1b1d8bb40cd0e7191 Mon Sep 17 00:00:00 2001 From: Avaya Aggarwal <119044997+OnePunchMonk@users.noreply.github.com> Date: Fri, 20 Mar 2026 15:40:41 +0530 Subject: [PATCH 1209/1405] cleanup: remove dead SDPA patches (#3488) [skip ci] Transformers 5.x routes attention through sdpa_attention.py and no longer calls the _prepare_4d_causal_attention_mask* or _expand_mask functions that these patches targeted.

A frozen copy of the model (the "feature network") extracts embeddings from both generated and ground-truth completions, and the generator is updated via REINFORCE to match the ground-truth feature moments. + +**Key advantages over SFT:** +- Operates on model rollouts (not teacher forcing), reducing distribution shift +- Provides dense sequence-level supervision without a task-specific verifier +- Improves both downstream accuracy and validation cross-entropy simultaneously + +**Key advantages over RLVR:** +- No reward model or verifier required — works on any (prompt, completion) data +- Applicable to non-verifiable tasks (e.g., raw code, translation, creative writing) +- Maintains distributional calibration (low feature-matching loss) + +## Two Modes + +EBFT supports two modes depending on your data format: + +### Structured Mode (`mode: structured`, default) +For **QA/instruction data** with prompt + completion pairs (e.g., OpenCodeInstruct, ALMA translation). +- Extends GRPOTrainer — uses vLLM for fast rollout generation +- RLOO advantages and clipped policy gradient from GRPO +- Feature-matching rewards replace external reward functions + +### Strided Mode (`mode: strided`) +For **unstructured text** without prompt/completion splits (e.g., raw code, prose, SwallowCode). +- Uses **strided block-parallel generation** — multiple short rollouts at different anchor points within a document +- No vLLM needed — generation uses custom strided attention masks +- Uses **torch flex_attention** with compiled block masks for efficient fused attention kernels (~2x faster than eager attention) +- Compatible with gradient checkpointing via automatic dtype normalization +- This is the core EBFT algorithm from the paper (Section F) + +### Common to both modes: +- **Frozen feature network** — deep copy of the model at initialization (frozen, eval mode) +- **Feature extraction** — hidden states at configurable layer depths (default: 25%, 50%, 75%), L2-normalized per layer before concatenation +- **Feature-matching rewards** — cosine similarity (alignment) minus pairwise dot-product (diversity), scaled by 2 per paper equation (7) +- **SVD whitening** — decorrelates feature dimensions; the paper shows removing it causes the largest degradation +- **CFM loss tracking** — conditional feature-matching loss (paper eq 2) logged as `ebft/cfm_loss` +- **FSDP2 compatible** — feature network stays outside FSDP wrapping (frozen, inference-only) + +## Quick Start + +### Structured Mode (QA data + vLLM) + +```bash +# 1.

The paper's ablation (Figure 7) shows removing whitening causes the largest performance degradation. Safe to use with `diversity_coef > 0`. +- **`diversity_coef`**: Default 1.0. Per the paper's Variant (i) (eq 49), alignment uses cosine similarity while diversity uses raw dot product. After whitening, both are bounded and on compatible scales. +- **`n_samples_per_prompt`**: Must be >= 2 for diversity and RLOO. 4 is the paper's default. +- **`ce_coef`**: The paper ablates `γ ∈ {0, 0.03, 0.1}`. `0.03` balances CE and RL signals; `0.1` causes CE to dominate the gradient. `0.0` gives pure feature matching. + +### Feature extraction +- **`feature_layers: [0.25, 0.5, 0.75]`**: Extracts and concatenates hidden states from 25%, 50%, 75% depth. Each layer is L2-normalized independently before concatenation. The paper shows this works better than mean pooling or single-layer extraction. +- **`embed_method: last_token`**: Uses the last token's hidden state per block. The paper shows this outperforms mean pooling (Figure 7). + +### Performance +- **`torch_compile: true`**: Recommended for strided mode. Provides additional speedup via graph compilation. +- **flex_attention**: Strided mode automatically uses `flex_attention` with compiled block masks when available (~2x faster than eager attention). Works with gradient checkpointing via automatic dtype normalization. Falls back to eager attention with dense 4D masks if flex_attention is unavailable. + +### Memory +- EBFT requires a frozen copy of the model (the feature network), roughly doubling model memory. +- **LoRA** is recommended to reduce trainable parameter memory. The feature network is always a frozen copy of the base model (without LoRA adapters). +- With 2 GPUs visible, the trainer automatically places the feature network on the second GPU. +- **FSDP2** is supported — the feature network stays outside FSDP wrapping since it's frozen and inference-only. With `cpu_ram_efficient_loading`, the feature network is loaded separately from pretrained weights. + +## Example Configs + +| Config | Mode | Model | Description | +|--------|------|-------|-------------| +| `llama-1b-ebft-opencode.yaml` | Structured | Llama-3.2-1B | QA coding with vLLM | +| `llama-1b-ebft-opencode-novllm.yaml` | Structured | Llama-3.2-1B | QA coding without vLLM | +| `llama-3b-ebft-strided-fft.yaml` | Strided | Llama-3.2-3B | Unstructured code with LoRA | +| `llama-1b-ebft-strided.yaml` | Strided | Llama-3.2-1B | Quick validation | + +## Citation + +```bibtex +@article{jelassi2026matching, + title={Matching Features, Not Tokens: Energy-Based Fine-Tuning of Language Models}, + author={Jelassi, Samy and Kwun, Mujin and Zhao, Rosie and Li, Yuanzhi and Fusi, Nicolo and Du, Yilun and Kakade, Sham M. and Domingo-Enrich, Carles}, + journal={arXiv preprint arXiv:2603.12248}, + year={2026} +} +``` diff --git a/examples/ebft/ebft_opencode.py b/examples/ebft/ebft_opencode.py new file mode 100644 index 0000000000..677949ba51 --- /dev/null +++ b/examples/ebft/ebft_opencode.py @@ -0,0 +1,28 @@ +""" +Dataset transform for nvidia/OpenCodeInstruct with EBFT. + +Maps the dataset's `input` (prompt) and `output` (code solution) fields +to the format expected by the EBFT trainer. +""" + + +def transform(cfg, *args, **kwargs): + def transform_fn(example, tokenizer=None): + return { + "prompt": [ + {"role": "user", "content": example["input"]}, + ], + "ground_truth": example["output"], + } + + return transform_fn, { + "remove_columns": [ + "id", + "domain", + "generation_algorithm", + "llm_judgement", + "unit_tests", + "tests_execution_status", + "average_test_score", + ] + } diff --git a/examples/ebft/ebft_pretrain.py b/examples/ebft/ebft_pretrain.py new file mode 100644 index 0000000000..27a1e54b90 --- /dev/null +++ b/examples/ebft/ebft_pretrain.py @@ -0,0 +1,31 @@ +""" +Dataset transform for unstructured text data with strided EBFT. + +Tokenizes raw text into fixed-length input_ids for the strided trainer. +Sequences are padded to sequence_len for uniform batching. +""" + + +def transform(cfg, *args, **kwargs): + seq_len = cfg.sequence_len + + def transform_fn(example, tokenizer=None): + text = example.get("question", example.get("text", "")) + if tokenizer is None: + return {"prompt": text} + + encoded = tokenizer( + text, + truncation=True, + max_length=seq_len, + padding="max_length", + add_special_tokens=True, + return_tensors=None, + ) + return { + "input_ids": encoded["input_ids"], + "attention_mask": encoded["attention_mask"], + "labels": list(encoded["input_ids"]), + } + + return transform_fn, {"remove_columns": ["question", "answer"]} diff --git a/examples/ebft/ebft_strided_structured.py b/examples/ebft/ebft_strided_structured.py new file mode 100644 index 0000000000..48743931aa --- /dev/null +++ b/examples/ebft/ebft_strided_structured.py @@ -0,0 +1,80 @@ +""" +Dataset transform for structured (prompt, completion) data with strided EBFT. + +Tokenizes prompt and completion separately, concatenates into a single +input_ids sequence, and marks prompt tokens with labels=-100 so the +strided trainer knows where to place anchors (completion span only). + +Works with datasets that have chat-style fields (e.g., nvidia/OpenCodeInstruct). +""" + + +def transform(cfg, *args, **kwargs): + seq_len = cfg.sequence_len + + def transform_fn(example, tokenizer=None): + # Extract prompt and completion from the example + prompt_text = example.get( + "input", example.get("prompt", example.get("question", "")) + ) + completion_text = example.get( + "output", example.get("completion", example.get("answer", "")) + ) + + if tokenizer is None: + return {"prompt": prompt_text} + + pad_id = tokenizer.pad_token_id or tokenizer.eos_token_id + + # Tokenize prompt and completion separately + prompt_enc = tokenizer( + prompt_text, + truncation=False, + add_special_tokens=True, + return_tensors=None, + ) + completion_enc = tokenizer( + completion_text, + truncation=False, + add_special_tokens=False, + return_tensors=None, + ) + + prompt_ids = prompt_enc["input_ids"] + completion_ids = completion_enc["input_ids"] + + # Truncate to fit within seq_len (prioritize keeping prompt + some completion) + total_len = len(prompt_ids) + len(completion_ids) + if total_len > seq_len: + # Truncate completion first, then prompt if needed + max_completion = seq_len -

Calls our vLLM server for model generation +2. Parses tool calls from model output +3. Executes tools against resource servers +4. Feeds tool results back to the model +5. Repeats until done, then calls /verify for reward +6. Returns token IDs + logprobs + reward to our rollout_func + +### Data Producer Architecture (Multi-Turn) + +When `nemo_gym_multi_turn: true`, the plugin automatically forces `use_data_producer: true` +which selects the `AxolotlAsyncGRPOTrainer`. The plugin then swaps the trainer's data +producer with `NemoGymDataProducer`, which: + +1. Gets a prompt batch from the dataset iterator +2. Expands by `num_generations` (one agent call per rollout) +3. Calls NeMo Gym agents via async HTTP (`aiohttp.gather`) +4. Parses responses into padded tensors (`RolloutDataset`) +5. Returns with `_pending_policy_logps=True` for deferred scoring + +The main thread then runs `_compute_deferred_scores()` which: +- Computes **policy logprobs** on the training model (GPU forward pass) +- Computes **IS correction** using agent's sampling logprobs vs training model logprobs +- Computes advantages with group-level normalization +- All downstream features work: replay buffer, re-roll, streaming, zero-adv skip + +With `async_prefetch: true`, the data producer runs in a background thread — giving ~3x +speedup as generation and training overlap. With `async_prefetch: false`, it runs +synchronously on the main thread (still uses the data producer protocol). + +### Weight Sync (LoRA Mode) + +With `vllm_lora_sync: true`, the plugin (or async trainer) replaces NCCL-based weight +sync with filesystem + HTTP: + +1. `accelerator.get_state_dict()` gathers LoRA weights from all ranks +2. Rank 0 saves adapter to `/tmp/lora_sync_*/vN/` +3. Rank 0 POSTs to `/set_lora_adapter/` on vLLM server +4. vLLM loads adapter natively via Punica kernels +5.

The model's own internal representations serve as the reward signal. This makes it particularly effective for: + +- Code generation (match features of known-good solutions) +- Instruction following with reference outputs +- Continual pretraining on unstructured text (strided mode) +- Multi-turn dialogue with reference conversations + +### Reward Formulation + +The EBFT reward for each generated completion is: + +``` +reward = alignment_coef * cosine_similarity(gen_features, gt_features) + - diversity_coef * mean_pairwise_similarity(gen_features) +``` + +- **Alignment**: How closely the generated output's internal representations match the ground truth.

Lower is better. +- **CFM loss** (Cross-Feature Matching): Tracks `||mean(gen_features) - gt_features||^2` as a diagnostic.

Instead of generating full completions with vLLM, it places **anchor points** at regular intervals throughout each document and generates short rollouts at each anchor using block-parallel attention. + +### How Block-Parallel Generation Works + +Given a document of length `S` tokens: + +1. **Anchor placement**: Starting at position `anchor_offset`, place anchors every `stride` tokens. Each anchor defines a block. +2. **Context window**: Each block sees `context_length` tokens of preceding context from the original document. +3. **Generation**: At each anchor, generate `generate_max_len` tokens autoregressively, conditioned only on the context window. +4. **Parallelism**: All blocks are processed in a single forward pass using a specialized attention mask that prevents information leakage between blocks. + +``` +Document: [tok0, tok1, ..., tok_S] + | | | + anchor_0 anchor_1 anchor_2 + | | | + [ctx][gen] [ctx][gen] [ctx][gen] +``` + +The attention mask ensures: + +- Prompt tokens use standard causal attention +- Each generated block attends to its own context window and its own preceding generated tokens +- Blocks do not attend to each other's generated tokens + +When `flex_attention` is available (PyTorch >= 2.5), the mask is compiled into efficient fused kernels.

This acts as a regularizer to prevent the model from drifting too far from the original distribution: + +```yaml +ebft: + ce_coef: 0.03 # Small CE coefficient + rl_coef: 1.0 # RL loss coefficient +``` + +The total loss is `rl_coef * rl_loss + ce_coef * ce_loss`.

The `remove_columns` in the kwargs dict removes columns that are no longer needed. Columns that your reward functions reference via `**kwargs` (like `answer`) must *not* be removed. + +:::{.callout-warning} +The reward module must be importable from the directory where you run `axolotl train`. If your reward file is `rewards.py`, the import path is `rewards.accuracy_reward`. If it is inside a package `my_rewards/scoring.py`, use `my_rewards.scoring.accuracy_reward`. +::: + +### Reward models (neural network rewards) + +Instead of a Python function, you can pass a HuggingFace model path as a reward function. TRL will load it as a reward model and use its scalar output as the reward: + +```yaml +trl: + reward_funcs: + - OpenAssistant/reward-model-deberta-v3-large-v2 + - rewards.format_reward + reward_weights: + - 1.0 + - 0.3 +``` + +### Using math_verify + +The `math_verify` library provides robust mathematical answer verification but uses `signal.alarm()` internally, which only works in the main thread. If you use `math_verify` in a reward function, set `reward_num_workers` to use subprocess workers: + +```yaml +trl: + reward_num_workers: 4 +``` + +Each worker runs in its own subprocess with its own main thread, so `signal.alarm()` works correctly. + + +## vLLM Setup + +GRPO requires a running vLLM server for generation. For a complete guide on server modes, LoRA sync, weight synchronization, and restart procedures, see [vLLM Serving](vllm_serving.qmd). + +The minimal setup: + +```yaml +vllm: + host: 0.0.0.0 + port: 8000 + gpu_memory_utilization: 0.85 + +trl: + use_vllm: true + vllm_lora_sync: true # Recommended with LoRA — faster sync, no NCCL contention + vllm_sync_interval: 5 # Sync weights every 5 steps +``` + +```bash +CUDA_VISIBLE_DEVICES=0 axolotl vllm-serve config.yaml # GPU 0: vLLM +CUDA_VISIBLE_DEVICES=1 axolotl train config.yaml # GPU 1: training +``` + +:::{.callout-warning} +vLLM must be restarted between experiments — stale weight syncs corrupt server state. See [Restart Requirements](vllm_serving.qmd#sec-restart). +::: + + +## Async Training Features + +Async GRPO overlaps generation and training to reduce wall-clock time. While the model trains on the current batch, the next batch is already being generated by vLLM. + +### Enabling async prefetch + +```yaml +trl: + use_data_producer: true + async_prefetch: true + prefetch_depth: 1 + vllm_sync_interval: 2 +``` + +- `use_data_producer: true` enables the data producer protocol (required for all async features). +- `async_prefetch: true` runs generation in a background thread. +- `prefetch_depth` controls how many batches to prefetch ahead (1 is usually sufficient). +- `vllm_sync_interval` controls how often LoRA weights are synced to vLLM (every N optimizer steps). Lower values mean fresher generations but more sync overhead. + +:::{.callout-tip} +Because the background thread generates with slightly stale model weights, async mode benefits from importance sampling correction (see next section). Enable `vllm_importance_sampling_correction: true` when using `async_prefetch: true`. +::: + +### Streaming partial batch + +Instead of scoring the entire batch at once, streaming mode scores one prompt group at a time. This reduces peak memory during scoring and enables finer-grained zero-advantage skipping. + +```yaml +trl: + streaming_partial_batch: true + streaming_min_groups: 1 +``` + +`streaming_min_groups` controls the minimum number of prompt groups scored per chunk. Setting it to 1 gives maximum granularity. + +### Zero-advantage batch skipping + +When all advantages in a micro-batch are zero (every completion in the group got the same reward), there is no learning signal. This feature skips the forward/backward pass entirely for such micro-batches. + +```yaml +trl: + skip_zero_advantage_batches: true # default +``` + +This is enabled by default and logged as `skipped_zero_adv_batches` in training metrics. It is a safety net, not a major optimization -- it only saves significant time when the model cannot solve any prompts in the batch. + +### Replay buffer + +The replay buffer caches rollout groups that had learning signal (non-zero reward variance) and replaces zero-signal groups in later batches. This improves data utilization when many prompts yield no reward variance. + +```yaml +trl: + replay_buffer_size: 100 + replay_recompute_logps: true +``` + +:::{.callout-warning} +When `replay_recompute_logps: false`, replayed data uses stale log-probabilities which creates an IS mismatch. Keep the default `true` unless you have a specific reason to disable it. +::: + +### Deferred re-rolling + +Prompts where the model gets zero reward for all generations are buffered and re-injected into later batches, when the model may have improved enough to produce useful completions. + +```yaml +trl: + reroll_start_fraction: 0.5 # Start re-rolling after 50% of training + reroll_max_groups: 1 # Max groups to replace per batch +``` + +Set `reroll_start_fraction: 1.0` to disable. This is most useful for tasks where the model starts weak but steadily improves. + +### Parallel reward workers + +Reward functions that use `signal.alarm()` (like `math_verify`) only work in the main thread. Parallel reward workers run each function in its own subprocess: + +```yaml +trl: + reward_num_workers: 4 +``` + +Work is sharded across workers by prompt group. For simple reward functions, a single worker is usually sufficient -- the overhead of IPC can exceed the computation time. + + +## Importance Sampling and Off-Policy Correction + +When using async prefetch, completions are generated from a slightly older policy. IS correction adjusts the gradient to account for this mismatch. + +```yaml +trl: + vllm_importance_sampling_correction: true + importance_sampling_level: token # 'token' recommended (especially with Liger kernel) + off_policy_mask_threshold: 0.5 # KL threshold — masks sequences that are too off-policy +``` + +Use `token` level IS. Sequence-level has numerical issues with Liger's chunked computation. The `off_policy_mask_threshold` (OPSM) is a safety net that drops sequences where KL divergence exceeds the threshold — 0.5 is a reasonable starting point. + +For detailed coverage of IS modes (`token_mask`, `token_truncate`, etc.), capping, and bias-corrected KL, see [vLLM Serving — IS Correction](vllm_serving.qmd#sec-weight-sync). + + +## Scaling + +### FP8 training + +FP8 quantization halves model VRAM usage with minimal impact on training quality. It does not significantly speed up computation for small models but allows larger models to fit in memory. + +```yaml +fp8: true +torch_compile: true +``` + +:::{.callout-warning} +FP8 requires patching for zero-padding edge cases. The `act_quant_kernel` can produce NaN when input is all zeros (padding positions). If you see NaN in grad norms, check whether your padding token embedding is non-zero. +::: + +### FSDP (Fully Sharded Data Parallel) + +FSDP distributes model parameters across multiple GPUs for training while vLLM runs on a separate GPU: + +```yaml +fsdp: + - full_shard + - auto_wrap +fsdp_config: + fsdp_transformer_layer_cls_to_wrap: Qwen2DecoderLayer +gradient_checkpointing_kwargs: + use_reentrant: false +``` + +Launch with: + +```bash +# GPU 0: vLLM +CUDA_VISIBLE_DEVICES=0 axolotl vllm-serve config.yaml + +# GPUs 0,1: Training (FSDP will use both visible GPUs) +CUDA_VISIBLE_DEVICES=0,1 axolotl train config.yaml +``` + +:::{.callout-warning} +`async_prefetch: true` can deadlock with FSDP because background threads perform unsynchronized FSDP collectives across ranks. With multi-GPU FSDP, only rank 0 generates in the background thread and results are broadcast to all ranks. If you still see hangs, set `async_prefetch: false`. +::: + +### DeepSpeed ZeRO-3 + +```yaml +deepspeed: deepspeed_configs/zero3_bf16.json +gradient_checkpointing_kwargs: + use_reentrant: true # Required -- non-reentrant causes CheckpointError with ZeRO-3 +``` + +:::{.callout-note} +DeepSpeed ZeRO-3 requires `use_reentrant: true` for gradient checkpointing. This is the opposite of the FSDP recommendation.

When the trainer needs new completions, vLLM wakes up and reclaims VRAM. + +::: {.callout-warning} +Colocate mode is significantly slower than server mode because generation and training cannot overlap. The GPU alternates between the two workloads. This mode is practical only for smaller models (up to ~3B on a 24 GB GPU). +::: + +**When to use colocate mode:** + +- You have exactly one GPU +- The model fits in memory with both vLLM and training active (with sleep mode), or is small enough to time-share +- You accept the performance tradeoff for simpler setup (no separate vLLM process to manage) + +**When to use server mode:** + +- You have two or more GPUs +- You want maximum throughput (generation overlaps with training via async prefetch) +- You are running larger models (7B+) + +## LoRA Sync {#sec-lora-sync} + +LoRA sync is the recommended weight synchronization method when training with LoRA adapters. Instead of merging adapter weights into the base model and broadcasting the full merged weights over NCCL, it saves only the LoRA adapter files to the filesystem and tells vLLM to load them natively. + +### How It Works + +1. The trainer calls `model.save_pretrained()` to write the LoRA adapter weights to a temporary directory +2. The trainer sends an HTTP POST to `/set_lora_adapter/` on the vLLM server +3. vLLM loads the adapter using its native LoRA support (Punica kernels) +4. Generation uses the updated adapter on the next request + +### Benefits + +- **Smaller sync payload**: Transfers ~40 MB of LoRA weights instead of ~1.4 GB+ of merged model weights (for a typical 0.5-3B model) +- **No NCCL communicator**: Eliminates the need for a cross-GPU NCCL communication channel, removing GPU contention between vLLM generation and weight sync +- **Faster sync**: ~200 ms per sync vs. 350 ms to 5+ seconds for NCCL merge sync +- **Simpler multi-GPU**: No need to set up NCCL groups between trainer and vLLM processes + +### Configuration + +```yaml +adapter: lora +lora_r: 32 +lora_alpha: 64 +lora_target_linear: true + +trl: + vllm_lora_sync: true # Enables LoRA sync mode + vllm_sync_interval: 5 # Sync every 5 training steps +``` + +Setting `vllm_lora_sync: true` automatically selects the LoRA-aware vLLM serve script (`axolotl.scripts.vllm_serve_lora`). You do not need to set `vllm.serve_module` manually. + +::: {.callout-important} +LoRA sync requires that you are training with a LoRA adapter (`adapter: lora` or `adapter: qlora`). It is not applicable to full fine-tuning. +::: + +## Weight Synchronization {#sec-weight-sync} + +During GRPO training, the policy model on the trainer is continuously updated via gradient steps. The vLLM server, however, still holds the old weights. Periodically, the trainer must push updated weights to vLLM so that future generations reflect the improved policy. + +### Sync Interval + +The `vllm_sync_interval` parameter controls how often weights are synced: + +```yaml +trl: + vllm_sync_interval: 5 # Sync every 5 optimizer steps +``` + +**Tradeoffs:** + +- **Lower interval** (e.g., 1-3): Fresher generations, better on-policy data, but more sync overhead per step +- **Higher interval** (e.g., 5-10): Less overhead, but generations become increasingly off-policy between syncs +- **Recommended**: 3-5 for most setups. Axolotl includes importance sampling correction (`vllm_importance_sampling_correction: true`) to handle mild distribution mismatch from stale vLLM weights. + +### Sync Methods + +| Method | Config | Payload | Mechanism | Typical Time | +|--------|--------|---------|-----------|-------------| +| **LoRA sync** | `vllm_lora_sync: true` | LoRA adapter only (~40 MB) | Filesystem + HTTP | ~200 ms | +| **NCCL merge sync** | Default (no lora_sync) | Full merged weights (~1.4 GB+) | HTTP trigger + NCCL broadcast | 350 ms - 5 s | + +::: {.callout-tip} +If you are training with LoRA (which is recommended for GRPO), always enable `vllm_lora_sync: true`. The performance difference is substantial, especially as training progresses and NCCL contention increases. +::: + +### Importance Sampling Correction + +When vLLM weights are stale (between syncs), the generated data is slightly off-policy. Axolotl can correct for this: + +```yaml +trl: + vllm_importance_sampling_correction: true + importance_sampling_level: token # 'token' or 'sequence' + off_policy_mask_threshold: 0.5 # KL threshold for masking stale sequences +``` + +- **Token-level IS** is recommended when using Liger kernel (sequence-level has numerical issues with chunked computation) +- **Off-policy sequence masking (OPSM)** drops sequences that have diverged too far from the current policy, providing a safety net against stale data + +## Restart Requirements {#sec-restart} + +::: {.callout-warning} +**vLLM must be restarted between training runs.** Weight syncs from a previous run leave the server in a corrupted state.

[PATCH 1274/1405] bump transformers to 5.5.4 and trl to latest 1.1.0 (#3603) * bump transformers to 5.5.4 and trl to latest 1.1.0 * more upgrades * update peft too * adapt lora_merge to peft 0.19 layer config API PEFT 0.19 requires a LoraConfig object on Linear/ParamWrapper/Conv layer constructors and moved use_rslora, use_dora, fan_in_fan_out, lora_dropout, and lora_bias into that config. Build the config per branch in _build_peft_layer_and_get_delta so the merge utility works with the upgraded peft. * allow lora_dropout on mixed attention+MoE configs under peft 0.19 PEFT 0.19's convert_peft_config_for_transformers auto-remaps old MoE target_modules (w1/w2/w3 on Mixtral, etc.) into target_parameters for transformers v5's fused 3D expert Parameters. Those targets get wrapped with ParamWrapper, which rejects lora_dropout != 0 because the 3D einsum can't factor dropout out of lora_B(lora_A(dropout(x))). Monkeypatch ParamWrapper.__init__ to internally use a copy of the LoraConfig with lora_dropout=0, so its dropout slot becomes nn.Identity while the shared config still delivers real dropout to sibling Linear LoRA layers (attention q/k/v/o). A probe runs the same conversion on a deep copy to detect the situation and emit a warning before patching. --- requirements.txt | 12 +-- src/axolotl/cli/utils/lora_merge.py | 34 +++++++-- src/axolotl/loaders/adapter.py | 109 ++++++++++++++++++++++++++++ 3 files changed, 143 insertions(+), 12 deletions(-) diff --git a/requirements.txt b/requirements.txt index fe4b674367..bb3fc8daaf 100644 --- a/requirements.txt +++ b/requirements.txt @@ -10,15 +10,15 @@ liger-kernel==0.7.0 packaging==26.0 huggingface_hub>=1.1.7 -peft>=0.18.1 +peft>=0.19.0,<0.20.0 tokenizers>=0.22.1 -transformers==5.5.3 +transformers==5.5.4 accelerate==1.13.0 -datasets==4.5.0 +datasets>=4.8.4,<4.9.0 deepspeed>=0.18.6,<0.19.0 -trl==0.29.0 -hf_xet==1.3.2 -kernels==0.12.2 +trl==1.1.0 +hf_xet==1.4.3 +kernels==0.13.0 fla-core==0.4.1 flash-linear-attention==0.4.1 diff --git a/src/axolotl/cli/utils/lora_merge.py b/src/axolotl/cli/utils/lora_merge.py index b7c436aede..a07395587d 100644 --- a/src/axolotl/cli/utils/lora_merge.py +++ b/src/axolotl/cli/utils/lora_merge.py @@ -315,15 +315,27 @@ class _FakeModule(nn.Module): "weight", nn.Parameter(base_tensor.clone(), requires_grad=False) ) + # ParamWrapper rejects dropout/fan_in_fan_out/lora_bias/use_dora, so + # build a minimal config with only the fields it accepts. + pw_config = LoraConfig( + r=r, + lora_alpha=lora_alpha, + lora_dropout=0.0, + fan_in_fan_out=False, + use_rslora=use_rslora, + use_dora=False, + lora_bias=False, + ) + with warnings.catch_warnings(): warnings.simplefilter("ignore", UserWarning) layer = ParamWrapper( fake, adapter_name=adapter_name, parameter_name="weight", + config=pw_config, r=r, lora_alpha=lora_alpha, - use_rslora=use_rslora, ) layer.lora_A[adapter_name].weight.data = lora_a layer.lora_B[adapter_name].weight.data = lora_b @@ -375,13 +387,18 @@ class _FakeModule(nn.Module): ) base_layer.weight.data = base_tensor.clone() + conv_config = LoraConfig( + r=r_total, + lora_alpha=lora_alpha, + use_rslora=use_rslora, + use_dora=use_dora, + ) layer = PeftConvCls( base_layer, adapter_name=adapter_name, + config=conv_config, r=r_total, lora_alpha=lora_alpha, - use_rslora=use_rslora, - use_dora=use_dora, ) layer.lora_A[adapter_name].weight.data = lora_a layer.lora_B[adapter_name].weight.data = lora_b @@ -410,15 +427,20 @@ class _FakeModule(nn.Module): or lora_config_dict.get("lora_fan_in_fan_out", False) ) - layer = LoraLinear( - base_layer, - adapter_name=adapter_name, + linear_config = LoraConfig( r=r_total, lora_alpha=lora_alpha, fan_in_fan_out=fan_in_fan_out, use_rslora=use_rslora, use_dora=use_dora, ) + layer = LoraLinear( + base_layer, + adapter_name=adapter_name, + config=linear_config, + r=r_total, + lora_alpha=lora_alpha, + ) layer.lora_A[adapter_name].weight.data = lora_a layer.lora_B[adapter_name].weight.data = lora_b diff --git a/src/axolotl/loaders/adapter.py b/src/axolotl/loaders/adapter.py index 6d0bd0fe19..3d662c0bb3 100644 --- a/src/axolotl/loaders/adapter.py +++ b/src/axolotl/loaders/adapter.py @@ -124,6 +124,101 @@ def _patched( LoraModel._axolotl_clippable_patched = True +def _peft_will_auto_convert_target_params(model, lora_config) -> bool: + """Check whether PEFT will auto-populate target_parameters for this model. + + PEFT 0.19's ``convert_peft_config_for_transformers`` rewrites old MoE + ``target_modules`` (e.g. ``w1``/``w2``/``w3`` on Mixtral) into + ``target_parameters`` (``gate_up_proj``/``down_proj``) because + transformers v5 fused those expert linears into 3D ``nn.Parameter`` + tensors.

HF's Gemma4TextModel.forward passes shared_kv_states (a mutable dict used for cross-layer K/V sharing) as a kwarg to every decoder_layer call. GradientCheckpointingLayer.__call__ then forms partial(super().__call__, **kwargs), and whichever checkpoint runs (axolotl's CPU_Offloaded_Gradient_Checkpointer or torch's stock checkpoint) captures that partial. The partial holds a reference to the dict, which holds the K/V tensors produced by store_full_length_kv layers. Those tensors stay pinned for the full duration of backward, and delayed ref-cycle cleanup in torch's caching allocator under FSDP2 + activation checkpointing bleeds the residual across steps. Observed symptom: VRAM climbs ~0.47 GiB/step from a 42 GiB baseline, OOMs around step 73 (~94 GiB peak) on Gemma-4 31B multimodal with gemma4_hybrid_attn_impl: true. Independent of seq len / image size. All-flex-attention path is flat but ~22x slower. Violated invariant: anything crossing an activation-checkpoint boundary must be a tensor (refcounted by autograd) or plain Python data -- never a mutable container holding tensor references. Fix (all in src/axolotl/monkeypatch/models/gemma4/fused_attn.py): * threading.local() store with _get/_set_shared_kv_states helpers * _patch_decoder_layer_call(): monkeypatches Gemma4TextDecoderLayer.__call__ to pop shared_kv_states from kwargs and stash it in TLS before delegating to GradientCheckpointingLayer. The partial formed downstream no longer references the dict. * fused_forward reads TLS first, falls back to kwarg for callers that bypass the patched __call__ (e.g. direct attention invocation). * wired into patch_gemma4_fused_attn; idempotent via a sentinel. TLS is overwritten on each new step's first decoder-layer call, so the previous step's dict is released promptly. No changes to hybrid dispatch, FSDP wrap policy, or any config behaviour. Works for hybrid, flex, and eager paths. Introduced by PR #3598 (commit b8358aa5). * Coderabbit comment: gemma4: clear TLS unconditionally in decoder-layer patched __call__ Overwrite the thread-local shared_kv_states store on every invocation (including with None) instead of only when the kwarg is present. The previous conditional write left stale dicts in TLS on any path that reaches Gemma4TextDecoderLayer.__call__ without a shared_kv_states kwarg — e.g. generation, eval hooks, or future HF refactors that make the kwarg optional. fused_forward would then silently consume a prior step's K/V dict instead of falling back to its own kwarg path. Unconditional write makes the invariant in the surrounding comment ("TLS is overwritten on each new step's first decoder-layer call, so the previous step's dict is released promptly") actually hold. No behavior change for the training happy path, which always passes the kwarg. Addresses CodeRabbit review on PR #3611 * fix: swap threading.local() for module-level store so autograd worker threads see shared_kv_states during backward recompute Previous commits fixed memory leak on 31B but caused type error with MOE Gemma4 variants - this fixes that: PR 3611's TLS variant only works when recompute runs on the same thread that set TLS during forward. PyTorch's C++ autograd engine (_engine_run_backward) spawns per-device worker threads to dispatch backward, and HF-Trainer gradient_checkpointing (stock torch.utils.checkpoint, non-reentrant / saved-tensor-hooks) fires unpack_hook -> recompute_fn on those worker threads. TLS set on the main thread during forward is invisible there, so _get_shared_kv_states() returns None and the consumer-layer lookup crashes with "'NoneType' object is not subscriptable" at fused_attn.py:97 (shared_kv_states[self.kv_shared_layer_index]). A plain module-level dict is visible to all threads in the process. Lifecycle is identical: the slot is overwritten each forward, releasing the previous step's dict and allowing its K/V tensors to be GC'd, so the original VRAM-leak fix still holds under FSDP2 AC too. * scope gemma4 shared_kv_states side channel to checkpointed training Update PR #3611 with gate for checkpointed training to avoid regressions across async flows. Added unit tests for kwargs pop, store-clear regression, and flag gating. Condensed verbose comments * add gemma4 cross-thread visibility test for shared_kv_states store Additional regression test for MoE gemma4 variants - asserts the module-level store is readable from threads other than the one that set it in response to previously observed 'NoneType' error * fix logger --------- Co-authored-by: Wing Lian --- src/axolotl/loaders/patch_manager.py | 11 +- .../monkeypatch/models/gemma4/fused_attn.py | 59 +++++- .../test_gemma4_fused_attn_patch.py | 171 ++++++++++++++++++ 3 files changed, 234 insertions(+), 7 deletions(-) create mode 100644 tests/monkeypatch/test_gemma4_fused_attn_patch.py diff --git a/src/axolotl/loaders/patch_manager.py b/src/axolotl/loaders/patch_manager.py index f32b7c12e8..8739655162 100644 --- a/src/axolotl/loaders/patch_manager.py +++ b/src/axolotl/loaders/patch_manager.py @@ -395,7 +395,16 @@ def _apply_model_specific_patches(self): patch_gemma4_fused_attn, ) - patch_gemma4_fused_attn() + # Shared-KV side channel when activation checkpointing (PR #3611). + fsdp_cfg = self.cfg.fsdp_config + needs_shared_kv_workaround = (not self.inference) and bool( + self.cfg.gradient_checkpointing + or self.cfg.activation_offloading + or (fsdp_cfg is not None and fsdp_cfg.activation_checkpointing) + ) + patch_gemma4_fused_attn( + install_shared_kv_workaround=needs_shared_kv_workaround + ) @staticmethod def _fix_nemotron_h_conversion_mapping(): diff --git a/src/axolotl/monkeypatch/models/gemma4/fused_attn.py b/src/axolotl/monkeypatch/models/gemma4/fused_attn.py index 7cb5c6beb3..2144b6c417 100644 --- a/src/axolotl/monkeypatch/models/gemma4/fused_attn.py +++ b/src/axolotl/monkeypatch/models/gemma4/fused_attn.py @@ -6,15 +6,29 @@ Usage: from axolotl.monkeypatch.models.gemma4.fused_attn import patch_gemma4_fused_attn - patch_gemma4_fused_attn() + # Pass install_shared_kv_workaround=True when activation checkpointing is enabled. + patch_gemma4_fused_attn(install_shared_kv_workaround=True) """ -import logging from typing import Callable import torch -logger = logging.getLogger(__name__) +from axolotl.utils.logging import get_logger + +logger = get_logger(__name__) + +# Module-level dict used as a side channel for shared KV states avoiding kwarg and TLS +# to prevent memory leak on gradient checkpoint enabled training (PR #3611) +_GEMMA4_SHARED_KV_STORE: dict = {"store": None} + + +def _set_shared_kv_states(store): + _GEMMA4_SHARED_KV_STORE["store"] = store + + +def _get_shared_kv_states(): + return _GEMMA4_SHARED_KV_STORE["store"] def _make_fused_forward(original_forward): @@ -30,7 +44,7 @@ def fused_forward( hidden_states: torch.Tensor, position_embeddings: torch.Tensor, attention_mask: torch.Tensor | None, - shared_kv_states: dict[int, tuple[torch.Tensor, torch.Tensor]], + shared_kv_states: dict[int, tuple[torch.Tensor, torch.Tensor]] | None = None, past_key_values=None, **kwargs, ) -> tuple[torch.Tensor, torch.Tensor | None]: @@ -39,6 +53,10 @@ def fused_forward( eager_attention_forward, ) + store = _get_shared_kv_states() + if store is not None: + shared_kv_states = store + input_shape = hidden_states.shape[:-1] hidden_shape = (*input_shape, -1, self.head_dim) eps = self.config.rms_norm_eps @@ -133,15 +151,44 @@ def fused_forward( return fused_forward -def patch_gemma4_fused_attn(): +def _patch_decoder_layer_call(): + """Strip `shared_kv_states` from decoder-layer kwargs and route via the + module-level side channel so the checkpoint partial cannot pin it (PR #3611).

Backend selection -> attn_implementation enum 2. Packing capability -> attn_supports_packing property 3. Flash-attn library dependency -> attn_uses_flash_lib property * compute attn capability flags in normalizer instead of properties * make attn_implementation the single source of truth * move attention-dependent validators to mode=after * migrate remaining consumers to canonical attn_implementation * expand attention tests + rewrite docs * migrate example configs to canonical attn_implementation * update doc snippets + reject gemma4-hybrid with non-FA2 backend * remove dead gemma4 branch in _set_attention_config * fix duplicate attn_implementation in gpt-oss yamls and flaky caplog tests * drop "Phase 2" naming from attn-implementation tests * regroup attn_implementation tests by feature concern * clean up verbose comments and remove MD Signed-off-by: Wing Lian Co-authored-by: Axolotl Swarm * fix(collator): pass return_dict=True at apply_chat_template top level for transformers 5.x In transformers 5.x, ProcessorMixin.apply_chat_template gained its own `return_dict` parameter (defaulting to False). When return_dict=False and tokenize=True the method returns out["input_ids"] directly — a 2-D tensor — rather than the full BatchFeature dict. The old code placed `return_dict=True` inside processor_kwargs. In transformers 5.x those kwargs are forwarded to the underlying processor call self(...) where _merge_kwargs silently ignores any key not present in MllamaProcessorKwargs (emitting a warning). The outer return_dict therefore stayed False, apply_chat_template returned the raw input_ids tensor, and the subsequent `batch["input_ids"]` attempted to index a 2-D tensor with the 9-character string "input_ids", producing: IndexError: too many indices for tensor of dimension 2 The fix is to pass return_dict=True as a top-level keyword argument to apply_chat_template (where it is actually consumed) and remove it from processor_kwargs (where it was silently dropped). No version guard is needed: transformers is pinned to ==5.5.4 in pyproject.toml. Adds a unit-level regression test (tests/test_mm_chat_collator.py) that mocks the processor to return a raw tensor when apply_chat_template is called without top-level return_dict=True, verifying the four invariants: process_rows returns a dict, input_ids is 2-D, labels is 2-D, and apply_chat_template receives return_dict=True as a top-level kwarg. Fixes: tests/e2e/test_llama_vision.py::TestLlamaVision::test_lora_llama_vision_multimodal_dataset Fixes: tests/e2e/test_llama_vision.py::TestLlamaVision::test_lora_llama_vision_text_only_dataset Signed-off-by: Wing Lian Co-authored-by: Axolotl Swarm * fix(collator): process_rows returns dict (BatchFeature) shape Two related changes for the multimodal chat collator under transformers 5.x: 1. Wrap apply_chat_template result in dict(...) so process_rows returns a plain dict rather than a BatchFeature instance. BatchFeature is a Mapping but not a dict; downstream code that did batch["labels"] = self.processing_strategy.process_labels(batch["input_ids"]) would index on a tensor when the result wasn't dict-shaped, raising IndexError: too many indices for tensor of dimension 2 2. Soften the regression test's contract from `dict` to `Mapping` so it exercises the actual semantic guarantee (key/value access) rather than the implementation detail (dict vs BatchFeature). Test guards against the original transformers 5.x breakage where apply_chat_template's return_dict default went from True to False. Includes regression test under tests/test_mm_chat_collator.py. Bug surfaced via swarm dispatch task_01KQHPNAYD8XARSNSDJVW1GPF6 against attn-implementation-refactor; squash-merged from agent commits 4de886fd + dc9fcf4f.

Co-Authored-By: Claude Opus 4.7 (1M context) * docs+types: address CodeRabbit nitpicks on PR #7 - builders/causal.py: add inline NOTE that multi-dataset configs reuse the first dataset's masking knobs (roles_to_train / train_on_eos) for all datasets — heterogeneous per-dataset overrides are not supported in the MM path today. - processing_strategies.py: annotate inner scanner helpers _match_prefix and _find_end with explicit types (Tensor, int, list[int] → bool / tuple[int, bool]) for readability. - docs/multimodal_assistant_mask.md: renumber the "Commits on this branch" list to 1-7 consecutive (previously skipped 3). Co-Authored-By: Claude Opus 4.7 (1M context) * fix(mm-mask): address two CodeRabbit findings on PR #7 1. Schema rejected `train_on_eos: "none"` despite the scanner honoring it. `_VALID_TRAIN_ON_EOS` accepts "none" and the design doc lists it, but `SFTDataset.train_on_eos` was `Literal["all", "turn", "last"]`, so YAML users hit a pydantic ValidationError at config load. Added "none" to the Literal and updated the description. 2. `cfg.role_boundaries: []` had split-personality semantics: the strategy ctor treated it as "replace built-ins with empty" while the collator plumbing treated it as "unset", and both the design doc and the MultiModalConfig schema help text promised wholesale replacement for any set value. Aligned on opt-in semantics across all four surfaces — a non-empty list replaces built-ins wholesale; unset or `[]` falls back to built-ins. Rationale: honoring `[]` literally yields all-masked labels and zero gradient, which is almost always a typo or leftover rather than a deliberate user action. Users who want to disable role masking should unset the field or use `train_on_inputs: true`. Also sharpened the fallback one-shot warning for strategies without built-in boundaries: names the consequence ("only pad and media tokens are masked, every other token contributes to loss") and points users at `cfg.role_boundaries` + docs/multimodal_assistant_mask.md instead of "see axolotl/processing_strategies.py for how to declare boundaries." Files: - src/axolotl/utils/schemas/datasets.py: Literal adds "none" - src/axolotl/processing_strategies.py: ctor truthiness check on role_boundaries_override; sharpened fallback warning - src/axolotl/utils/schemas/multimodal.py: role_boundaries description now calls out opt-in + empty-list fallback semantics - docs/multimodal_assistant_mask.md: same clarification in the Semantics block; updated the fallback-path detection paragraph to quote the new warning text - tests/test_processing_strategies.py: +2 regressions (test_sft_dataset_schema_accepts_all_supported_train_on_eos_values, test_empty_role_boundaries_override_falls_back_to_builtin); 63/63 pass Co-Authored-By: Claude Opus 4.7 (1M context) * doc cleanup * fix(mm-mask): CodeRabbit findings + lint fix on PR #3625 Pre-commit failure: trailing newline missing on docs/multimodal_assistant_mask.md (end-of-file-fixer hook). Six CodeRabbit findings addressed: 1. Scanner: non-trainable role's end marker ignored ``include_end``. Under ``train_on_eos="all"``, the shared ``[/INST]`` token (user-end with ``include_end=False``, intentionally re-matched as assistant-start) leaked into loss via the user branch on Pixtral / Mistral V7 Tekken. Fix: gate the non-trainable branch on ``best_match.include_end`` to mirror the trainable branch. 2. Gemma3 ``boi_token`` lookup used ``tokenizer.special_tokens_map.get("boi_token")``, which never fires on real checkpoints (``special_tokens_map`` only holds HF's standard slots — bos/eos/pad/unk/...). Swap to direct attribute read ``getattr(tokenizer, "boi_token", None)``, matching what ``transformers.models.gemma3.processing_gemma3`` itself does. Updated the ``_gemma_tokenizer`` test fixture to mirror real-model shape so the test exercises the production code path. 3. GLM dispatcher only registered ``Glm46VProcessor`` (GLM-4.6V / GLM-4.7V). Real ``Glm4vProcessor`` (GLM-4V / GLM-4.1V) users fell through to the base fallback. Both processors ship identical media-token markers, so register both under the shared ``Glm4vProcessingStrategy`` with independent try/except import blocks. Updated class docstring. +2 dispatcher regressions. 4. Gemma3 ``process_labels`` hardcoded 262144 for the soft image token. Resolve dynamically via ``tokenizer.convert_tokens_to_ids("")`` with unk-id guard; fall back to 262144 only if the string isn't in vocab. Mirrors ``Gemma4ProcessingStrategy.process_labels`` pattern. 5. ``build_collator`` was called twice per ``build()`` (eval + train passes), producing two identical ``MM collator: ...`` INFO banners on startup. Gate the log on ``is_eval=False`` so only the training pass emits it. 6. Removed unused ``_mistral_common_stub`` pytest fixture (13 refs → 0, always returned ``None``; the dispatcher already handles missing ``mistral_common`` via lazy import + ``try/except``). Added ``test_scanner_train_on_eos_all_with_non_trainable_include_end_false`` — a focused scanner-level lock-in for finding #1, independent of any specific VLM strategy. Test count: 63 → 68 passing. Local ``pre-commit run --all-files`` green. Co-Authored-By: Claude Opus 4.7 (1M context) * chore(mm-mask): hoist .tolist() out of scanner; shorten comments/docstrings - Scanner perf: convert labels[i] to a Python list once per row so _match_prefix / _find_end operate on list slices instead of re-materializing Tensor slices via .tolist() on every probe. Cuts O(n*boundaries) CPython↔C boundary crossings per batch. - Markdown lint (MD001, MD040): promote two h3 section headings to h2 under the h1; add `text` language to the verify-at-runtime fenced block. - Shorten verbose comments/docstrings added in recent commits to bare-minimum "why" notes matching the repo's existing style. 68/68 tests, 8/8 pre-commit hooks still pass. --- docs/multimodal_assistant_mask.md | 84 ++ src/axolotl/core/builders/causal.py | 41 + src/axolotl/processing_strategies.py | 1029 +++++++++++++++----- src/axolotl/utils/schemas/datasets.py | 4 +- src/axolotl/utils/schemas/multimodal.py | 62 ++ tests/test_processing_strategies.py | 1164 +++++++++++++++++++++++ 6 files changed, 2155 insertions(+), 229 deletions(-) create mode 100644 docs/multimodal_assistant_mask.md create mode 100644 tests/test_processing_strategies.py diff --git a/docs/multimodal_assistant_mask.md b/docs/multimodal_assistant_mask.md new file mode 100644 index 0000000000..339ab420f8 --- /dev/null +++ b/docs/multimodal_assistant_mask.md @@ -0,0 +1,84 @@ +# Multimodal assistant-only loss masking + +## Correct placement + +```yaml +# Top-level: only train_on_inputs lives here. +train_on_inputs: false + +datasets: + - path: data/train.jsonl + type: chat_template + roles_to_train: # per-dataset — this is what the MM scanner reads + - assistant + train_on_eos: turn # per-dataset — same + +test_datasets: + - path: data/val.jsonl + type: chat_template + split: train + roles_to_train: + - assistant + train_on_eos: turn +``` + +## How to verify at runtime + +`build_collator` logs the resolved knobs at INFO: + +```text +MM collator: train_on_inputs=False roles_to_train=['assistant'] train_on_eos=turn role_boundaries_override=none +``` + +If `roles_to_train` logs as `None`, the YAML knobs are not reaching the +scanner — check that they are under `datasets[0]`, not at the root. + +Each verified strategy additionally logs its resolved boundary token ids at +strategy init (e.g. `<|turn>model` → `[105, 4368]`, `` → `[106]` for +Gemma 4).

Axolotl ReLoRA optimizer reset scope (#3646) * Fix Axolotl ReLoRA optimizer reset scope * fix: make relora reset method honor relora_prune_ratio When relora_prune_method='reset' and relora_prune_ratio is explicitly set, the ratio was silently ignored and replaced with the hardcoded _FULL_RESET_RATIO (0.999). Fix by moving the default-ratio logic to ReLoRACallback.on_step_begin: None maps to _FULL_RESET_RATIO for reset and 0.9 for other methods. reset_optimizer now uses the same random pruning path for both 'random' and 'reset'. Also consolidate three-layer default mismatch: schema default for relora_prune_method is now 'magnitude' (single canonical source); dataclass defaults for both fields changed to None to eliminate the conflicting fallback layer. Tests updated: removed the test case that verified the old broken behavior (reset ignoring ratio), added two cases proving reset honors the passed ratio. E2E reset fixture now uses ratio=0.5 to make it unambiguous that the ratio is honored. * Fix ReLoRA uint8 pruning regression --------- Signed-off-by: Wing Lian Co-authored-by: Axolotl Swarm --- .github/workflows/tests.yml | 2 +- src/axolotl/core/builders/causal.py | 6 +- src/axolotl/core/training_args_base.py | 15 +- src/axolotl/monkeypatch/relora.py | 98 +++++++++---- src/axolotl/utils/schemas/peft.py | 22 ++- tests/e2e/solo/test_relora_llama.py | 67 ++++++++- tests/monkeypatch/test_relora.py | 186 +++++++++++++++++++++++++ 7 files changed, 360 insertions(+), 36 deletions(-) create mode 100644 tests/monkeypatch/test_relora.py diff --git a/.github/workflows/tests.yml b/.github/workflows/tests.yml index e21e60ab57..6b298ade02 100644 --- a/.github/workflows/tests.yml +++ b/.github/workflows/tests.yml @@ -72,7 +72,7 @@ jobs: exclude: - python_version: "3.14" pytorch_version: "2.9.1" - timeout-minutes: 20 + timeout-minutes: 25 steps: - name: cleanup node diff --git a/src/axolotl/core/builders/causal.py b/src/axolotl/core/builders/causal.py index aa1678523a..b5f365bce7 100644 --- a/src/axolotl/core/builders/causal.py +++ b/src/axolotl/core/builders/causal.py @@ -286,10 +286,14 @@ def build(self, total_num_steps): ) if self.cfg.relora and self.cfg.jagged_restart_steps: - if self.cfg.relora_prune_ratio: + if self.cfg.relora_prune_ratio is not None: training_arguments_kwargs["relora_prune_ratio"] = ( self.cfg.relora_prune_ratio ) + if self.cfg.relora_prune_method: + training_arguments_kwargs["relora_prune_method"] = ( + self.cfg.relora_prune_method + ) if self.cfg.jagged_restart_steps: training_arguments_kwargs["jagged_restart_steps"] = ( diff --git a/src/axolotl/core/training_args_base.py b/src/axolotl/core/training_args_base.py index 427a80a468..e9727dbb16 100644 --- a/src/axolotl/core/training_args_base.py +++ b/src/axolotl/core/training_args_base.py @@ -83,13 +83,18 @@ class AxolotlTrainingMixins: default=None, metadata={"help": "The number of processes to use for data processing"}, ) - relora_steps: Optional[int] = field( + relora_prune_ratio: Optional[float] = field( default=None, - metadata={"help": "how often to reset for ReLoRA"}, + metadata={ + "help": ( + "prune ratio for optimizer state pruning; " + "defaults to 0.999 for reset method, 0.9 for others" + ) + }, ) - relora_prune_ratio: Optional[float] = field( - default=0.9, - metadata={"help": "prune ratio for magnitude pruning of the optimizer"}, + relora_prune_method: Optional[str] = field( + default=None, + metadata={"help": "optimizer state pruning method: magnitude | random | reset"}, ) jagged_restart_steps: Optional[int] = field( default=None, diff --git a/src/axolotl/monkeypatch/relora.py b/src/axolotl/monkeypatch/relora.py index cf93c32dda..3d33ab204d 100644 --- a/src/axolotl/monkeypatch/relora.py +++ b/src/axolotl/monkeypatch/relora.py @@ -6,9 +6,8 @@ import shutil from functools import partial from pathlib import Path -from typing import Dict, List, Union +from typing import Dict, List, Literal, Union -import bitsandbytes as bnb import peft import safetensors.torch as st import torch @@ -28,9 +27,15 @@ LOG = get_logger(__name__) +try: + import bitsandbytes as bnb +except ImportError: # pragma: no cover - optional dependency for 8-bit merge paths + bnb = None + @torch.no_grad() def magnitude_pruning_(tensor, prune_ratio): + """Zero the lowest ``prune_ratio`` fraction of values by absolute magnitude, in place.""" tensor_magnitude = torch.abs(tensor) threshold = torch.quantile( tensor_magnitude.flatten().to(dtype=torch.float32), prune_ratio @@ -40,15 +45,43 @@ def magnitude_pruning_(tensor, prune_ratio): tensor.mul_(mask.to(dtype=tensor.dtype)) +@torch.no_grad() +def random_pruning_(tensor, prune_ratio): + """Zero a random ``prune_ratio`` fraction of values, in place.""" + mask = ( + torch.rand(tensor.shape, dtype=torch.float32, device=tensor.device) + > prune_ratio + ) + tensor.mul_(mask.to(dtype=tensor.dtype)) + + +# 0.999 mirrors the reference implementation.

Changes: - Add torch_empty_cache_steps config option, passed directly to TrainingArguments for native CUDA cache clearing by the Trainer - Add gc_collect_steps config option for explicit control over Python gc.collect() frequency, which the native Trainer does not handle - Deprecate gc_steps with automatic migration: positive values map to both torch_empty_cache_steps and gc_collect_steps; negative values (-1) map only to gc_collect_steps for epoch-end/eval GC - Refactor GCCallback to use gc_collect_steps parameter name and reorder operations (gc.collect() before empty_cache for better memory reclamation) - Add comprehensive tests for config migration and GCCallback Closes #2689 * fix: address review feedback - Fix gc_collect_steps description inconsistency (default is None, not 0) - Add missing gc_collect_steps assertion in test_new_options_take_precedence * style: fix ruff lint and format violations Co-Authored-By: Claude Sonnet 4.6 * chore: comment cleanup --------- Co-authored-by: Claude Sonnet 4.6 Co-authored-by: NanoCode012 --- src/axolotl/core/builders/base.py | 9 ++- src/axolotl/utils/callbacks/__init__.py | 18 +++-- src/axolotl/utils/schemas/config.py | 44 ++++++++++- tests/patched/test_validation.py | 49 ++++++++++++ tests/utils/callbacks/test_gc_callback.py | 90 +++++++++++++++++++++++ 5 files changed, 202 insertions(+), 8 deletions(-) create mode 100644 tests/utils/callbacks/test_gc_callback.py diff --git a/src/axolotl/core/builders/base.py b/src/axolotl/core/builders/base.py index 9cceb1bf81..ad62837cae 100644 --- a/src/axolotl/core/builders/base.py +++ b/src/axolotl/core/builders/base.py @@ -122,8 +122,11 @@ def get_callbacks(self) -> list[TrainerCallback]: if self.cfg.resume_from_checkpoint: callbacks.append(SkipEvalOnResumeCallback()) - if self.cfg.gc_steps: - callbacks.append(GCCallback(gc_steps=self.cfg.gc_steps)) + gc_collect_steps = getattr(self.cfg, "gc_collect_steps", None) or getattr( + self.cfg, "gc_steps", None + ) + if gc_collect_steps: + callbacks.append(GCCallback(gc_collect_steps=gc_collect_steps)) if self.cfg.dynamic_checkpoint and self.cfg.dynamic_checkpoint.enabled: from axolotl.utils.callbacks.dynamic_checkpoint import ( @@ -573,6 +576,8 @@ def _set_base_training_args( "dion_rank_fraction", "dion_rank_multiple_of", "dataset_num_proc", + # memory management + "torch_empty_cache_steps", ]: if hasattr(self.cfg, arg) and getattr(self.cfg, arg) is not None: training_args_kwargs[arg] = getattr(self.cfg, arg) diff --git a/src/axolotl/utils/callbacks/__init__.py b/src/axolotl/utils/callbacks/__init__.py index edb61441b4..0a278f6ecb 100644 --- a/src/axolotl/utils/callbacks/__init__.py +++ b/src/axolotl/utils/callbacks/__init__.py @@ -878,15 +878,21 @@ def on_train_begin( class GCCallback(TrainerCallback): - """Callback to garbage collect torch cache""" + """Runs ``gc.collect()`` + ``torch.cuda.empty_cache()`` on + ``gc_collect_steps`` intervals and on eval/save/epoch boundaries that + the Trainer's native ``torch_empty_cache_steps`` doesn't cover.

With the default field_messages=("messages",) behavior is unchanged. - Updated __call__ docstring to mention the configurable third source key and align the Raises wording with the actual error message. * docs: clarify field_messages is a rename-only escape hatch Document that the recommended multimodal column name is messages with the OpenAI-style role/content schema, and that field_messages is a rename-only escape hatch for upstream data stored under a different column name. The inner schema must still match one of the two documented formats. Addresses the suggestion from @ved1beta. * test: add unit tests for ProcessingStrategy field_messages plumbing Add 20 unit tests covering: - _normalize_field_messages: None/str/list/falsy entries - _is_legacy_schema: requires both from and value to flag legacy - _get_messages_field: configured field takes priority over a stale messages column, falls back to messages when the configured field is absent - ProcessingStrategy.__call__: canonical messages/conversations keys, custom field with auto-detected OpenAI vs ShareGPT schema, and the ValueError raised when none of the supported source keys are present.

Those belong in commit messages / PR descriptions and rot fast. +- Prefer one short line max. +- Don't add planning/decision/analysis markdown files unless explicitly requested. + ## Key Documentation - [Getting Started](docs/getting-started.qmd) — quickstart tutorial diff --git a/CLAUDE.md b/CLAUDE.md new file mode 120000 index 0000000000..47dc3e3d86 --- /dev/null +++ b/CLAUDE.md @@ -0,0 +1 @@ +AGENTS.md \ No newline at end of file diff --git a/cicd/Dockerfile-uv.jinja b/cicd/Dockerfile-uv.jinja index c24512ed3b..acf84ad1d9 100644 --- a/cicd/Dockerfile-uv.jinja +++ b/cicd/Dockerfile-uv.jinja @@ -26,9 +26,9 @@ RUN uv pip install packaging==26.0 setuptools==78.1.1 RUN uv pip install torchvision RUN uv pip uninstall causal_conv1d RUN if [ "$AXOLOTL_EXTRAS" != "" ] ; then \ - uv pip install --no-build-isolation -e .[deepspeed,flash-attn,ring-flash-attn,optimizers,ray,$AXOLOTL_EXTRAS] $AXOLOTL_ARGS; \ + uv pip install --no-build-isolation -e .[deepspeed,optimizers,ray,$AXOLOTL_EXTRAS] $AXOLOTL_ARGS; \ else \ - uv pip install --no-build-isolation -e .[deepspeed,flash-attn,ring-flash-attn,optimizers,ray] $AXOLOTL_ARGS; \ + uv pip install --no-build-isolation -e .[deepspeed,optimizers,ray] $AXOLOTL_ARGS; \ fi # Override with nightly HF packages for nightly builds diff --git a/docs/attention.qmd b/docs/attention.qmd index f7fa5b4561..64820fb6ef 100644 --- a/docs/attention.qmd +++ b/docs/attention.qmd @@ -177,21 +177,6 @@ Recommended for Turing GPUs or below (e.g. Colab T4). ::: -### Shifted Sparse Attention - -::: {.callout-warning} - -Planned for deprecation.

Only `gradient_accumulation_steps` is what the Ray worker re-validate rejects when both are set; `batch_size` must still derive on the controller because `calculate_total_num_steps` divides by it. Without this fix: `TypeError: unsupported operand type(s) for /: 'float' and 'NoneType'` at trainer.py:519. 2. prepare_optim_env mutated `cfg.fsdp = True` when migrating from fsdp_config-style configs. The schema now types `fsdp: list[str] | None`, so the bool fails Ray worker re-validation with `list_type` ValidationError. Every downstream caller already handles `cfg.fsdp_config or cfg.fsdp`, so the mutation is gratuitous — drop it. The TODO to remove the cfg.fsdp check entirely in 0.12 stays. 3. peft 0.19's `_maybe_shard_state_dict_for_tp` reads `base_layer.weight.device` unconditionally. The FakeExperts test mock uses `target_parameters` style (gate_up_proj / down_proj), so it legitimately has no `.weight`. Stub a zero-size buffer.

Splitting the sequence breaks this. - The Solution (`ring-flash-attention`): An efficient communication protocol is used. To compute attention for its local sequence chunk, each GPU passes its Key-Value (KV) cache to its neighbor in a "ring." After `N-1` steps, every GPU has seen the KV-cache from all other GPUs, allowing it to compute the correct attention values for its chunk. This is implemented using the highly optimized `flash-attention` kernel at each step. +- **Mamba/SSM Hybrid Models**: For hybrid architectures (Nemotron-H, Falcon-H1, Granite MoE Hybrid), attention layers use ring attention as above, while SSM (Mamba2) layers use P2P state passing across ranks with an additive output correction.

This lets models that declare fp32 norms for training stability train under FSDP2 while the rest of the model runs in bf16/fp16. FSDP1 enforces flat-param dtype uniformity within each wrap group, which is incompatible with keeping norms in fp32; the validator therefore requires fsdp_version: 2. Matching: patterns without a "." match type(module).__name__ as a suffix (catches LlamaRMSNorm, Qwen3RMSNorm, AfmoeRMSNorm, nn.LayerNorm, etc.); patterns containing a "." match the fully qualified class path exactly. Defaults to ["RMSNorm", "LayerNorm"]. Signed-off-by: Wing Lian * fixup! feat(fsdp2): address review findings + fix CI caplog assertions - matcher: skip empty/whitespace-only patterns (cls_name.endswith("") is True for any class, which would silently match everything). - validator: also require fsdp_config to be set, not just fsdp_version==2. fsdp_config is the canonical "is_fsdp" signal elsewhere in the codebase (used by check_fsdp_torch_version, sample_packing validators, etc.). - tests: temporarily flip propagate=True on the `axolotl` logger so pytest caplog can see the warnings. axolotl.cli.configure_logging() sets propagate=False at import time, which is the documented reason the assertions were failing in CI even though the warnings were firing visibly in stdout. - comment: replace multi-line rationale near the fp32_norms helpers with a one-line summary (the longer version lives in the PR description). Signed-off-by: Wing Lian * test(fsdp2): multi-GPU e2e for fp32_norms with dtype-preservation assertion The existing fp32_norms tests are pure-CPU and monkeypatch fully_shard — they cover the matcher logic and validator guard rails but never exercise the actual FSDP2 path that motivated this PR. Adds tests/e2e/multigpu/test_fsdp2_fp32_norms.py: spawns a 2-GPU `axolotl train` subprocess with `fp32_norms: true` + `fsdp_version: 2` + `bf16: true` on tiny-qwen3-129m (full FT, 2 steps) and asserts: 1. Training completes — the original FSDP1 flat-param dtype crash can't recur because we're on FSDP2 with the per-module MixedPrecisionPolicy. 2. All RMSNorm params are float32 after step 1 — captured via a test-only TrainerCallback in tests/e2e/multigpu/_fp32_norms_dtype_capture.py, dumped to JSON at $FP32_NORMS_DTYPE_DUMP_PATH on rank 0. 3. At least one non-norm param is bfloat16 — proves the two FSDP2 MixedPrecisionPolicy groups are independent (catches a silent globally-fp32 fallback that would technically satisfy assertion 2 but defeat the point of the feature). The dtype-capture plugin is plumbed in via the test's yaml `plugins:` list, with PYTHONPATH= on the subprocess env so the tests.e2e.multigpu._fp32_norms_dtype_capture module resolves.

Under use_kernels=True (force-enabled by KernelsArgs for the ScatterMoE path), from_pretrained calls model.kernelize(), whose attach_hidden_kernels step does register_module(name, fn) for each _hidden_kernels entry. register_module rejects the non-Module function: TypeError: ...apply_rotary_pos_emb is not a Module subclass with a follow-on AttributeError from the cleanup path.

Registers the ScatterMoE kernel from the local `libs/scattermoe_lora` package (includes fused LoRA support via Triton kernels). -2. Patches the model's `SparseMoeBlock` forward method with the optimized ScatterMoE implementation via the HF `kernels` library. - -### SonicMoE -1. Resolves the model's MoE block class(es) from `constants.py`. -2. Patches the forward method with SonicMoE's optimized CUTLASS kernels and registers a weight converter for the interleaved gate/up projection format. -3. Supports pluggable routing strategies (see routing table below). - -Both paths use the shared `resolve_moe_block_classes` utility in `constants.py` for model-type-to-class resolution. - -## Model Support Matrix - -Most models use the **SwiGLU** activation (`silu(gate) * up`). Gemma 4 uses **GEGLU** (`gelu(gate) * up`). ScatterMoE supports any gated activation (activation is applied in Python between kernel calls). SonicMoE supports SwiGLU, GEGLU, and REGLU via its `ActivationType` enum. - -### Routing strategies - -| Routing Strategy | Description | ScatterMoE | SonicMoE | -|---|---|:---:|:---:| -| softmax → topk | Softmax over experts, select top-K, optional renormalization | Yes | Yes | -| softmax → group selection → topk | Softmax, select top groups (sum of top-2 per group), topk from selected groups, renorm + scaling | No | Yes | -| sigmoid → topk (with groups) | Sigmoid + bias correction, group-based masking, topk from masked scores, weights from original sigmoid | Yes | Yes | -| sigmoid → topk (no groups) | Sigmoid + bias correction, straight topk (n_group=1) | Yes | Yes | -| softmax → bias correction → topk | Softmax, bias via `gate.moe_statics`, topk, gather from original probs, clamp-based renorm | No | Yes | -| softmax → group_limited_greedy | Softmax, group selection (max per group), topk, scale only (no renorm) | No | Yes | -| softmax → topk via gate.wg | Softmax, gate weight at `gate.wg.weight` (not `gate.weight`), always renormalize | No | Yes | -| softmax → topk + per_expert_scale | RMSNorm → scale → proj → softmax → topk → renorm → per-expert learned scales | Yes | Yes | -| fused topk → softmax | Routing + expert computation fused in a single kernel | No | Planned | - -### Per-model support - -| Model Type | Architecture | Routing | ScatterMoE | SonicMoE | -|---|---|---|:---:|:---:| -| `qwen2_moe` | Qwen2-MoE | softmax → topk | **Yes** | **Yes** | -| `qwen3_moe` | Qwen3-MoE | softmax → topk | **Yes** | **Yes** | -| `qwen3_5_moe` | Qwen3.5-MoE | softmax → topk | **Yes** | **Yes** | -| `qwen3_5_moe_text` | Qwen3.5-MoE (VLM text) | softmax → topk | **Yes** | **Yes** | -| `qwen3_next` | Qwen3-Next | softmax → topk | **Yes** | **Yes** | -| `qwen3_vl_moe` | Qwen3-VL-MoE | softmax → topk | **Yes** | **Yes** | -| `qwen3_omni_moe` | Qwen3-Omni (Thinker + Talker) | softmax → topk | **Yes** | **Yes** | -| `olmoe` | OLMoE | softmax → topk | **Yes** | **Yes** | -| `mixtral` | Mixtral | softmax → topk | **Yes** | **Yes** | -| `minimax` | MiniMax | softmax → topk | **Yes** | **Yes** | -| `mistral4` | Mistral 4 | softmax → group → topk | No | **Yes** | -| `glm_moe_dsa` | GLM-MoE DSA (GLM 5) | sigmoid → topk (groups) | **Yes** | **Yes** | -| `deepseek_v3` | DeepSeek-V3 | sigmoid → topk (groups) | **Yes** | **Yes** | -| `glm4_moe` | GLM4-MoE | sigmoid → topk (groups) | **Yes** | **Yes** | -| `glm4_moe_lite` | GLM4-MoE Lite (GLM 4.7 Flash) | sigmoid → topk (groups) | **Yes**\* | **Yes** | -| `glm4v_moe` | GLM4v-MoE | sigmoid → topk (groups) | **Yes** | **Yes** | -| `minimax_m2` | MiniMax M2 | sigmoid → topk (no groups) | **Yes** | **Yes** | -| `ernie4_5_moe` | ERNIE 4.5 MoE | softmax → bias → topk | No | **Yes** | -| `deepseek_v2` | DeepSeek-V2 | softmax → group_limited_greedy | No | **Yes** | -| `hunyuan_v1_moe` | HunYuan V1 MoE | softmax → topk (gate.wg) | No | **Yes** | -| `gemma4_text` | Gemma 4 (26B-A4B) | softmax → topk + per_expert_scale | **Yes**\*\* | **Yes**\*\* | -| `gpt_oss` | GPT-OSS | fused topk → softmax | No | Planned | - -\* `glm4_moe_lite` with ScatterMoE may have issues — see Limitations. - -\*\* Gemma 4 uses `experts_implementation: scattermoe` path (registered via `ExpertsInterface`) instead of SparseMoeBlock patching, since Gemma 4 embeds MoE directly in its decoder layer (no separate SparseMoeBlock).

The K-axis OCP block layout (last storage dim) matches `experts.gate_up_proj` natural shape `[E, N, K]`, so the caller's existing `.transpose(2, 1)` post-step keeps producing the kernel's `[E, K, N]` weight tile unchanged. `HFScatterMoEGatedMLP.forward` now also routes through the selective path whenever the experts hold MXFP4 weights — full-tensor MX dequant of 256-expert models is prohibitive and the kernel needs bf16 input. Tests (CUDA-only) compare against a bf16 baseline produced by the same MXTensor's full dequant; outputs are bitwise identical for both forward and backward (dX, dA, dB) across small [E=8,K=128,N=256] and representative [E=32,K=2048,N=1024] shapes, and across all four combinations of \`use_fused_dX\` / \`use_fused_gather\`. Signed-off-by: Wing Lian * feat(scattermoe-lora): fused mxfp4 dequant in triton kernel Add MX-aware forward and dX kernels that consume an ``MXWeights`` container (packed uint8 + E8M0 scales) directly, so the base-weight tile is dequantized inside the K-loop instead of through a materialized bf16 buffer. The K-loop loads two FP4 values per uint8 byte, looks them up in a 16-entry codebook tensor (``±{0, 0.5, 1, 1.5, 2, 3, 4, 6}``), multiplies by ``2^(scale_byte - 127)``, and casts to bf16 for the matmul. ``BLOCK_K`` is constrained to a multiple of the OCP block size (32) so each tile aligns with whole scale blocks; an MX-aware autotune pruner accounts for the extra packed/scale SMEM. The dX kernel reuses the *forward* MX layout (block axis = K, the dX output axis) — for each (K_tile, N_tile) sub-tile, nibbles decode along the K rows (the byte is shared by two adjacent K rows) and scales broadcast within their MX block. This avoids the dequant + re-quantize "pre-transpose" the spec suggested and the extra MX-rounding error that round-trip would have introduced. ``ScatterMoELoRA.forward`` now accepts either a dense tensor or an ``MXWeights``; the MX branch always selects the fused-dX and fused-gather backward kernels (the non-fused dX path would have to materialize a bf16 weight tile, defeating the win). Unit tests cover forward, dX, dA, dB parity for small [E=8, K=128, N=256] and representative [E=32, K=2048, N=1024] shapes; tolerances are calibrated to bf16 MMA noise (atomic-add ordering and FMA reordering between the full-E baseline and compact-active MX path). Integration test exercises a tiny synthetic DeepSeek-V4-style MoE block (E=8, hidden=512, intermediate=256, top_k=2) end-to-end through both Strategy A and Strategy B with LoRA disabled. Signed-off-by: Wing Lian * chore(scattermoe-lora): mxfp4 forward/backward benchmark Add ``bench_mxfp4.py`` and committed results for the representative DeepSeek-V4-style shape (E=128, K=2048, N=1024, top_k=8, M=4096, rank=16). Reports ms/iter, tokens/s, peak GPU memory, and HBM bandwidth utilisation for three configurations: bf16 baseline, Strategy A (selective dequant), Strategy B (fused MX). On the RTX PRO 6000 Blackwell, the all-active-experts shape used here doesn't exercise selective dequant's memory savings (active = E = 128) — A pays the cost of materialising the full bf16 dequant buffer per step (~9 GB peak vs 1.9 GB for B) while still routing through the bf16 kernel. B halves A's wall time (~12 ms vs 30 ms) by eliminating the buffer, but stays slower than the bf16 baseline (5 ms) which assumes the bf16 weights already exist in memory. Signed-off-by: Wing Lian * bench(scattermoe-lora): mxfp4 sparse-routing benchmark numbers Signed-off-by: Wing Lian * bench(scattermoe-lora): mxfp4 seqlen sweep with load-balanced routing Signed-off-by: Wing Lian * fix(scattermoe-lora): correct mx forward smem accounting The MX-aware autotune pruner for the forward kernel under-accounted SMEM: it computed the packed-tile cost as BLOCK_N * BLOCK_K/2 and the scale-tile cost as BLOCK_N * BLOCK_K/MX_BLOCK_SIZE, but the actual tl.load issues a full [BLOCK_N, BLOCK_K]-shaped uint8 fetch for both buffers (the packed buffer reads each byte twice because K_byte = K // 2 indexes a [BLOCK_K]-wide vector; the scale buffer broadcasts within each MX_BLOCK_SIZE K-block). Bring the forward pruner up to the same conservative full-tile accounting already used by _prune_dX_mx_configs. Without this, on the [E=128, K=2048, N=1024] shape with the typical GPU SMEM caps, two to six high-stage configs that were previously selectable would have overflowed SMEM at launch under correct accounting — a silent OOM-in-the-future risk. Signed-off-by: Wing Lian * docs(scattermoe-lora): align mx dx kernel docstring with implementation The file-level docstring for the MXFP4 kernels described the dX kernel as using a pre-transposed [E, K, N/2] layout produced by a 'mx_pre_transpose_for_dx' helper. That helper doesn't exist; the dX kernel actually reuses the forward [E, N, K/2] layout, iterating the N reduction in outer tiles and decoding nibbles along the K rows of each tile. Rewrite the docstring to describe what the code actually does, including the rationale — reusing the forward buffer avoids the dequant + re-quantize round-trip that a pre-transpose would require and keeps dX numerics free of a second MX rounding error stacked on top of the forward quantization. Signed-off-by: Wing Lian * chore(scattermoe-lora): mx code-review nit cleanup F4: Hoist 'is_mxfp4_param' import from inside 'HFScatterMoEGatedMLP.forward' to the top of layers.py — it was being re-imported every step on the hot path. F5: Add a thin compatibility shim for torchao MXTensor internals access in mx_weights.py. The MX paths in selective_dequant.py / mx_weights.py used to reach into 'mx_param.qdata', 'mx_param.scale', 'mx_param.kernel_preference' and call 'MXTensor(...)' with positional args directly. That works at the pinned torchao 0.17.0 but is fragile to internal renames in future torchao releases. Funnel through three helpers — '_mx_qdata', '_mx_scale', '_construct_mxtensor_subset' — that use 'getattr' fallbacks for the buffer attributes and pass the constructor's optional args via 'getattr' too. Single point of pain, no API change. F7: Remove the unused 'NO_K_MASK' heuristic + tl.constexpr param from the dX MX kernel '_scatter2scatter_lora_dX_mx'. The dX kernel never references it (its inner loop masks N, not K), so the constexpr just forced extra autotune key entries. F8: Consolidate the duplicate '_torchao_mxtensor_cls()' definitions (one in selective_dequant.py, one in mx_weights.py) into a single definition in mx_weights.py. selective_dequant.py imports it. Signed-off-by: Wing Lian * test(scattermoe-lora): strengthen mx backward test coverage F3: 'test_strategy_a_backward_fused_variants' previously used 'torch.ones_like(output)' as the grad input and asserted only on dX. A uniform grad zeros out cross-token differences in the fused-gather accumulation, masking reordering bugs; restricting the assertion to dX silently let the dA/dB paths go unchecked across the four '(use_fused_dX, use_fused_gather)' production variants. * Drive the backward with 'torch.randn_like(output) * 0.1'. * Capture and assert dA and dB parity across all four variants using the same 'row_idx' gather pattern as 'test_strategy_a_backward_matches_bf16'. * Forward and dX are still asserted bitwise via 'torch.equal'. dA/dB fall back to atol/rtol = 1e-3 because the fused dA/dB kernel uses 'atomic_add' across N-block programs and the in-flight program count differs between the full-E baseline and the compact-active path; combined with FMA reordering, the 'use_fused_dX=True' variants accumulate ~1 bf16 ULP of unavoidable atomic-order noise. The new bound is still an order of magnitude below that noise floor, so it catches real bugs. F9: The 'test_strategy_b_backward_matches_bf16' dX comparison runs at 'atol=0.5, rtol=2e-2' (small) / 'atol=2.0, rtol=3e-2' (representative) to allow for accumulated bf16 MMA noise over the N reduction. Those bounds are appropriate for legitimate per-element drift but would also admit a uniform multiplicative bug — e.g. an off-by-one on the E8M0 exponent that scales every dX element by 2x. Add a guard alongside the existing 'torch.allclose': mask out near-zero baseline elements (relative to 'bf16_dX.abs().max()'), then require the per-element ratio 'mx_dX / bf16_dX' to have std < 0.5. A uniform multiplicative bug pushes that std to ~0 while the mean shifts; a real-bug per-element drift pushes the std up. This crosscuts the allclose check rather than replacing it. Signed-off-by: Wing Lian * bench(scattermoe-lora): exclude per-iter setup from timed window The previous bench harness did a fresh '.clone()' of x and a 'requires_grad_(True)' on cloned lora A/B tensors every iter inside the timed window. That accounts for buffer allocation, not kernel cost, and biases the numbers toward whichever path produced the smallest activations. Restructure the runners so: * 'x' is cloned once into a leaf tensor with 'requires_grad_(True)' inside 'bench()' (outside the timed warmup + timed loop). * LoRA A/B leaf tensors are constructed once in the runner factory, not per iter. * Each iter calls the runner which sets 'x.grad = A.grad = B.grad = None' (cheap, no GPU sync) so the autograd graph for the timed iteration is fresh and grads don't accumulate. Re-run all three configs end-to-end after this change (dense E=128, sparse E=256 / 10-active, balanced E=256 M-sweep at M ∈ {256, 1024, 4096, 16384}) and refresh the numbers in bench_mxfp4_results.md. Headers and table structure are unchanged. The qualitative ordering holds (Strategy A wins at low active/E, Strategy B wins near active/E ≈ 1, and Strategy A still OOMs across the balanced sweep on the workstation with vLLM colocated), with per-cell numbers within single-digit percent of the prior runs. Signed-off-by: Wing Lian * style(scattermoe-lora): apply pre-commit auto-fixes and mypy fixes Signed-off-by: Wing Lian * fix(scattermoe-lora): mxfp4 shape validation + torchao version messages Signed-off-by: Wing Lian * lint and PR review fixes * fix(scattermoe-lora): restore lint task fixes + add missing forward parity assertions Wing's "lint and PR review fixes" commit (9007a829) reverted three fixes from the prior lint pass. Restore them: 1. parallel_linear_lora.py: use isinstance(expert_weights, MXWeights) directly so mypy can narrow the union — the `is_mx` boolean alias blocks narrowing and re-introduces 2 union-attr errors. 2. bench_mxfp4.py: assert template is not None before the MXTensor(...) constructor — the chunked converter initializes template to None then sets it inside the loop, which mypy can't prove non-None at the call site (6 None-attr errors). 3. test_mxfp4_expert_weights.py: the F841 on fwd_tol was actually a smell of dropped logic. Both backward tests (test_strategy_a_backward_matches_bf16 and test_strategy_b_backward_matches_bf16) compute the forward outputs out_b/out_a/out_s, run backward, and assert gradients match — but never assert that the forward outputs match. A forward bug producing a constant offset (and therefore zero gradient delta) would slip past the bwd-only checks. Add the missing torch.equal(out_b, out_a) for Strategy A (bitwise contract) and torch.allclose(out_b, out_s, **fwd_tol) for Strategy B (MX tol).

Extrapolating from the dense E=128 case above (Strategy A peak + ~8.6 GB at 128 active experts), the E=256 / 256-active dequant peak would + be ~17 GB — over the available headroom. +- **Active-expert count is essentially E at every sampled M.** Under a + load-balance-regularized router (per-token N(0,1) noise + N(0,0.5) per-expert + bias), `E[active] ≈ E · (1 − (1 − top_k/E)^M)`. With E=256 / top_k=8 this + yields ≥ 215 unique experts even at M=256 and saturates at 256 by M ≈ 16K. + Balanced routing therefore does **not** generate a low-active regime at + these token counts — i.e. the A-vs-B crossover does not appear in this + sweep; B wins by default because A does not fit. +- **B vs bf16:** Strategy B is consistently 1.9–2.9× slower than the bf16 + baseline (similar to the dense E=128 ratio of ~2.3×). HBM utilization for + both is modest (B 0.4–1.6 %, bf16 2.6–17.2 %), suggesting the kernels are + compute- or scheduling-bound for these shapes, not bandwidth-bound. +- **Where the A-vs-B crossover lives, by theory:** Strategy A is preferred + when `num_active / E` is small enough that the dequant cost is offset by + the cheaper bf16 matmul — the prior `sparse` row (10/256 active, A=5.75 ms + vs B=8.95 ms) sits in that regime.

charset=UTF-8 Content-Transfer-Encoding: 8bit * feat(scattermoe-lora): selective dequant for mxfp4 expert weights Add an MXFP4 branch to `selective_expert_weights()` that detects a torchao `MXTensor` parameter (elem_dtype=float4_e2m1fn_x2) and dequantizes only the active experts via index-then-construct of a compact sub-MXTensor. The K-axis OCP block layout (last storage dim) matches `experts.gate_up_proj` natural shape `[E, N, K]`, so the caller's existing `.transpose(2, 1)` post-step keeps producing the kernel's `[E, K, N]` weight tile unchanged. `HFScatterMoEGatedMLP.forward` now also routes through the selective path whenever the experts hold MXFP4 weights — full-tensor MX dequant of 256-expert models is prohibitive and the kernel needs bf16 input. Tests (CUDA-only) compare against a bf16 baseline produced by the same MXTensor's full dequant; outputs are bitwise identical for both forward and backward (dX, dA, dB) across small [E=8,K=128,N=256] and representative [E=32,K=2048,N=1024] shapes, and across all four combinations of \`use_fused_dX\` / \`use_fused_gather\`. Signed-off-by: Wing Lian * feat(scattermoe-lora): fused mxfp4 dequant in triton kernel Add MX-aware forward and dX kernels that consume an ``MXWeights`` container (packed uint8 + E8M0 scales) directly, so the base-weight tile is dequantized inside the K-loop instead of through a materialized bf16 buffer. The K-loop loads two FP4 values per uint8 byte, looks them up in a 16-entry codebook tensor (``±{0, 0.5, 1, 1.5, 2, 3, 4, 6}``), multiplies by ``2^(scale_byte - 127)``, and casts to bf16 for the matmul. ``BLOCK_K`` is constrained to a multiple of the OCP block size (32) so each tile aligns with whole scale blocks; an MX-aware autotune pruner accounts for the extra packed/scale SMEM. The dX kernel reuses the *forward* MX layout (block axis = K, the dX output axis) — for each (K_tile, N_tile) sub-tile, nibbles decode along the K rows (the byte is shared by two adjacent K rows) and scales broadcast within their MX block. This avoids the dequant + re-quantize "pre-transpose" the spec suggested and the extra MX-rounding error that round-trip would have introduced. ``ScatterMoELoRA.forward`` now accepts either a dense tensor or an ``MXWeights``; the MX branch always selects the fused-dX and fused-gather backward kernels (the non-fused dX path would have to materialize a bf16 weight tile, defeating the win). Unit tests cover forward, dX, dA, dB parity for small [E=8, K=128, N=256] and representative [E=32, K=2048, N=1024] shapes; tolerances are calibrated to bf16 MMA noise (atomic-add ordering and FMA reordering between the full-E baseline and compact-active MX path). Integration test exercises a tiny synthetic DeepSeek-V4-style MoE block (E=8, hidden=512, intermediate=256, top_k=2) end-to-end through both Strategy A and Strategy B with LoRA disabled. Signed-off-by: Wing Lian * chore(scattermoe-lora): mxfp4 forward/backward benchmark Add ``bench_mxfp4.py`` and committed results for the representative DeepSeek-V4-style shape (E=128, K=2048, N=1024, top_k=8, M=4096, rank=16). Reports ms/iter, tokens/s, peak GPU memory, and HBM bandwidth utilisation for three configurations: bf16 baseline, Strategy A (selective dequant), Strategy B (fused MX). On the RTX PRO 6000 Blackwell, the all-active-experts shape used here doesn't exercise selective dequant's memory savings (active = E = 128) — A pays the cost of materialising the full bf16 dequant buffer per step (~9 GB peak vs 1.9 GB for B) while still routing through the bf16 kernel. B halves A's wall time (~12 ms vs 30 ms) by eliminating the buffer, but stays slower than the bf16 baseline (5 ms) which assumes the bf16 weights already exist in memory.

Bring the forward pruner up to the same conservative full-tile accounting already used by _prune_dX_mx_configs. Without this, on the [E=128, K=2048, N=1024] shape with the typical GPU SMEM caps, two to six high-stage configs that were previously selectable would have overflowed SMEM at launch under correct accounting — a silent OOM-in-the-future risk. Signed-off-by: Wing Lian * docs(scattermoe-lora): align mx dx kernel docstring with implementation The file-level docstring for the MXFP4 kernels described the dX kernel as using a pre-transposed [E, K, N/2] layout produced by a 'mx_pre_transpose_for_dx' helper. That helper doesn't exist; the dX kernel actually reuses the forward [E, N, K/2] layout, iterating the N reduction in outer tiles and decoding nibbles along the K rows of each tile. Rewrite the docstring to describe what the code actually does, including the rationale — reusing the forward buffer avoids the dequant + re-quantize round-trip that a pre-transpose would require and keeps dX numerics free of a second MX rounding error stacked on top of the forward quantization. Signed-off-by: Wing Lian * chore(scattermoe-lora): mx code-review nit cleanup F4: Hoist 'is_mxfp4_param' import from inside 'HFScatterMoEGatedMLP.forward' to the top of layers.py — it was being re-imported every step on the hot path. F5: Add a thin compatibility shim for torchao MXTensor internals access in mx_weights.py. The MX paths in selective_dequant.py / mx_weights.py used to reach into 'mx_param.qdata', 'mx_param.scale', 'mx_param.kernel_preference' and call 'MXTensor(...)' with positional args directly. That works at the pinned torchao 0.17.0 but is fragile to internal renames in future torchao releases. Funnel through three helpers — '_mx_qdata', '_mx_scale', '_construct_mxtensor_subset' — that use 'getattr' fallbacks for the buffer attributes and pass the constructor's optional args via 'getattr' too. Single point of pain, no API change. F7: Remove the unused 'NO_K_MASK' heuristic + tl.constexpr param from the dX MX kernel '_scatter2scatter_lora_dX_mx'. The dX kernel never references it (its inner loop masks N, not K), so the constexpr just forced extra autotune key entries. F8: Consolidate the duplicate '_torchao_mxtensor_cls()' definitions (one in selective_dequant.py, one in mx_weights.py) into a single definition in mx_weights.py. selective_dequant.py imports it. Signed-off-by: Wing Lian * test(scattermoe-lora): strengthen mx backward test coverage F3: 'test_strategy_a_backward_fused_variants' previously used 'torch.ones_like(output)' as the grad input and asserted only on dX. A uniform grad zeros out cross-token differences in the fused-gather accumulation, masking reordering bugs; restricting the assertion to dX silently let the dA/dB paths go unchecked across the four '(use_fused_dX, use_fused_gather)' production variants. * Drive the backward with 'torch.randn_like(output) * 0.1'. * Capture and assert dA and dB parity across all four variants using the same 'row_idx' gather pattern as 'test_strategy_a_backward_matches_bf16'. * Forward and dX are still asserted bitwise via 'torch.equal'. dA/dB fall back to atol/rtol = 1e-3 because the fused dA/dB kernel uses 'atomic_add' across N-block programs and the in-flight program count differs between the full-E baseline and the compact-active path; combined with FMA reordering, the 'use_fused_dX=True' variants accumulate ~1 bf16 ULP of unavoidable atomic-order noise. The new bound is still an order of magnitude below that noise floor, so it catches real bugs. F9: The 'test_strategy_b_backward_matches_bf16' dX comparison runs at 'atol=0.5, rtol=2e-2' (small) / 'atol=2.0, rtol=3e-2' (representative) to allow for accumulated bf16 MMA noise over the N reduction. Those bounds are appropriate for legitimate per-element drift but would also admit a uniform multiplicative bug — e.g. an off-by-one on the E8M0 exponent that scales every dX element by 2x. Add a guard alongside the existing 'torch.allclose': mask out near-zero baseline elements (relative to 'bf16_dX.abs().max()'), then require the per-element ratio 'mx_dX / bf16_dX' to have std < 0.5. A uniform multiplicative bug pushes that std to ~0 while the mean shifts; a real-bug per-element drift pushes the std up. This crosscuts the allclose check rather than replacing it. Signed-off-by: Wing Lian * bench(scattermoe-lora): exclude per-iter setup from timed window The previous bench harness did a fresh '.clone()' of x and a 'requires_grad_(True)' on cloned lora A/B tensors every iter inside the timed window. That accounts for buffer allocation, not kernel cost, and biases the numbers toward whichever path produced the smallest activations. Restructure the runners so: * 'x' is cloned once into a leaf tensor with 'requires_grad_(True)' inside 'bench()' (outside the timed warmup + timed loop). * LoRA A/B leaf tensors are constructed once in the runner factory, not per iter. * Each iter calls the runner which sets 'x.grad = A.grad = B.grad = None' (cheap, no GPU sync) so the autograd graph for the timed iteration is fresh and grads don't accumulate. Re-run all three configs end-to-end after this change (dense E=128, sparse E=256 / 10-active, balanced E=256 M-sweep at M ∈ {256, 1024, 4096, 16384}) and refresh the numbers in bench_mxfp4_results.md. Headers and table structure are unchanged. The qualitative ordering holds (Strategy A wins at low active/E, Strategy B wins near active/E ≈ 1, and Strategy A still OOMs across the balanced sweep on the workstation with vLLM colocated), with per-cell numbers within single-digit percent of the prior runs.

Restore them: 1. parallel_linear_lora.py: use isinstance(expert_weights, MXWeights) directly so mypy can narrow the union — the `is_mx` boolean alias blocks narrowing and re-introduces 2 union-attr errors. 2. bench_mxfp4.py: assert template is not None before the MXTensor(...) constructor — the chunked converter initializes template to None then sets it inside the loop, which mypy can't prove non-None at the call site (6 None-attr errors). 3. test_mxfp4_expert_weights.py: the F841 on fwd_tol was actually a smell of dropped logic. Both backward tests (test_strategy_a_backward_matches_bf16 and test_strategy_b_backward_matches_bf16) compute the forward outputs out_b/out_a/out_s, run backward, and assert gradients match — but never assert that the forward outputs match. A forward bug producing a constant offset (and therefore zero gradient delta) would slip past the bwd-only checks. Add the missing torch.equal(out_b, out_a) for Strategy A (bitwise contract) and torch.allclose(out_b, out_s, **fwd_tol) for Strategy B (MX tol). Signed-off-by: Wing Lian * don't worry about flash-attn direct patches for now * feat(tiled-mlp): support MoE block classes in patcher Extend patch_tiled_mlp to discover MoE block classes ({prefix}SparseMoeBlock / MoeMLP / MoE) and patch the routing+expert forward when scattermoe-lora is active. The kernels library installs HFScatterMoEGatedMLP.forward per instance during model.kernelize(), which shadows class-level patches. Add a post-model-load step (patch_tiled_mlp_moe_instances) that re-wraps each MoE block instance so tiling layers on top of the kernels-installed forward instead of being bypassed. Falls back to the existing dense {prefix}MLP / {prefix}TextMLP path when no MoE block class exists. The gpt_oss special case for DeepSpeedTiledMLPMoE is preserved and extended to every MoE block. Signed-off-by: Wing Lian * fix(tiled-mlp): defer FSDP2 reshard + correct per-shard grad accumulation Two backward-pass correctness fixes in TiledMLP.backward. 1) Defer FSDP2 post-backward reshard across the tile loop. The backward issues one torch.autograd.backward per shard. Under FSDP2 (torch.distributed.fsdp.fully_shard), the first inner backward triggers the wrapping FSDPModule's post-backward hook, which reshards parameters; subsequent shards then recompute against only-local DTensor shards. Silent gradient corruption at best, crash at worst. LinkedIn's Liger-Kernel PR #1128 fixed this for FSDP1 with FSDP.summon_full_params(writeback=True). That API does not exist in FSDP2. The PyTorch 2.11 FSDP2 surface is FSDPModule.set_reshard_after_backward(False) — toggle off around the tile loop, restore the prior value, and issue one explicit reshard() afterwards. The wrapping FSDPModule is discovered by walking the global _module_state_mapping registry (FSDP2 is typically applied at the decoder-layer level, so the MLP itself is rarely the FSDPModule). Result is cached on the MLP instance so the walk runs once. No-op under DDP, single-GPU, or DeepSpeed. DeepSpeedTiledMLPMoE is left alone — DeepSpeed coordinates its own gather and the two backends are mutually exclusive. 2) Replace the hook-based GradientAccumulator with inline fp32 accumulation. The previous implementation called grad_accumulator.install_hooks() inside every shard iteration, so the N-th shard ran N stacked hooks that each accumulated the same shard contribution — and on the last shard the manually-set param.grad was then re-added by AccumulateGrad, doubling it. The accumulator also scaled by 1/N, but sequence-dim sharded gradients are additive (not averaged). Combined, param.grad came out ~2x-2.5x the analytical value. Inline accumulation captures param.grad after each shard's inner backward, sums into a per-param fp32 accumulator, clears the running grad, and writes the total back once at the end (preserving any pre-existing .grad from earlier graph segments).

Designed to be launched with `torchrun --nproc-per-node=2 -m pytest tests/e2e/multigpu/test_tiled_mlp_fsdp2.py`. Skips with a clear reason on a 1-GPU executor or when launched without torchrun. Verified to pass on a 2-GPU runner (RTX PRO 6000 Blackwell). Signed-off-by: Wing Lian * feat(scattermoe-lora): shared dequant buffer across tile shards Adds shared_dequant_across_shards() which hoists the MXFP4 dequant out of the per-shard selective path. The orthogonal tiled wrapper calls selective_expert_weights once per shard; when active-expert sets overlap (the common case under softmax routing) the dequant is wasted work. The helper computes the union of active experts across all shards, dequantizes that union once, and returns per-shard remaps so each shard's parallel_linear_lora call uses the correct slice. Bitwise contract: a shard's gathered slice is byte-identical to the per-shard selective_expert_weights output, verified by test_shared_dequant_helper.py with N=4 overlapping shards plus disjoint and single-shard regression cases. Signed-off-by: Wing Lian * fix(tiled-mlp): default grad accumulator to param dtype, skip redundant casts The orthogonal TiledMLP wrapper pre-allocated an fp32 accumulator the size of every compute param, then cast each shard's bf16 ``param.grad`` to fp32 inside the loop before adding it. For E=128 / hidden=2048 / intermediate=8192 MoE training in bf16 that's roughly 17 GiB of fp32 buffer on the gate_up_proj alone — net 2x parameter-side memory regression vs. simply accumulating at the param's own dtype. The per-shard ``grad.to(fp32)`` cast was also a per-shard HBM bandwidth tax that dominated the wall-clock regression at intermediate=8192. Match what AccumulateGrad does in the unsharded backward: accumulate at the param's own dtype, skip the cast when shard-grad dtype matches the accumulator dtype, and only cast back to param dtype at write-back when the buffer dtype differs. fp32 accumulation is opt-in via AXOLOTL_TILED_MLP_ACCUM_FP32=1 for callers who care about bf16 round-off in very-large-N-shard sums. The dead ``GradientAccumulator`` class (no longer called after the inline-accumulation refactor in b13375a0) is updated to the same defaults — param-dtype accumulator, gradient_scale=1.0 — so it is in a coherent state if anyone re-introduces a hook-based path. Signed-off-by: Wing Lian * test(tiled-mlp): strengthen tiled-vs-untiled grad parity Add three regression guards for the TiledMLP gradient-accumulator fix: 1) ``test_tiled_dense_mlp_grad_parity_nonuniform_weights`` and ``test_tiled_moe_grad_parity_nonuniform_weights`` exercise shards in {1, 2, 4} with non-uniform per-token upstream weights. A mean-vs-sum scaling bug in the per-shard accumulator (the historical ``gradient_scale = 1/total_shards``) would show up as roughly ``(N-1)/N`` relative drift in the param grads. The old tests used a single shard count and uniform-magnitude upstream, which allowed the bug to slip through. 2) ``test_tiled_dense_mlp_grad_parity_bf16`` runs the same parity at bf16 to lock the default param-dtype accumulator path (no fp32 buffer) against regression. 3) ``test_tiled_grad_accumulator_dtype_matches_param_dtype`` is an allocation-side guard: spy on ``torch.zeros_like`` during a bf16 tiled backward and assert none of the per-param accumulator allocations request fp32. A future change that re-introduces the fp32 buffer by default would fail this check without needing a memory-resident bench. Signed-off-by: Wing Lian * fix(tiled-mlp): default to ~32K tokens/shard, not ceil(seq/hidden) The previous heuristic put only ~2K tokens/shard at long context — well below the MoE Triton kernel's BLOCK_M sweet spot. An empirical sweep at seq ∈ {64K, 128K, 256K, 512K} showed 3.2× speed-up at 64–256K and 2.1× at 512K from raising per-shard tokens to ~32K, with only a modest peak-mem cost (~5–10 GiB extra at seq=256K) because the routed intermediate buffer dominates and scales linearly with per-shard tokens. Bench data is operator-archived locally; the headline numbers are included in the PR description. The 32K target is empirical, not theoretical — it's the largest tokens-per-shard that fits at seq up to 256K without OOM and stays inside the cuBLAS large-batch_count safe regime that surfaces a separate bug at seq=512K + s=16. Operators can override via cfg_num_shards for niche cases (smaller intermediate, larger top_k). Also includes ruff-format cleanup of cherry-picked commits.

The crash is reproducible on the bench shape (T=32K tokens/shard, top_k=8, hidden=2048, intermediate=8192) and is a downstream symptom of an int32 pointer-offset overflow in the upstream ``scatter2scatter`` Triton kernel during the up-projection — at that shape its output buffer is 2**32 elements, so ``M_block * stride_ym`` overflows int32 for the trailing rows. Add three repro tests in tests/integrations covering: * fast-path bit-identity vs the raw kernel below the threshold, * non-corruption at the overflow shape via the int32-safe wrapper, * end-to-end ``parallel_linear`` smoke at the failing bench shape. The tests are marked ``pytest.mark.skip`` pending the fix in the next commit; the follow-up "un-mark" commit re-enables them so they guard the fix going forward. Symbols imported inside each test body (``_scatter2scatter_int32_safe``, ``_SCATTER2SCATTER_INT32_LIMIT``) land alongside the fix in the next commit, so the skipped tests do not fail collection at this point in the history. Signed-off-by: Wing Lian fix(scattermoe-lora): work around cuBLAS large-batch_count failure in gates @ output_expanded The originally-reported symptom — ``CUBLAS_STATUS_EXECUTION_FAILED`` at parallel_experts.py:72 — is NOT a cuBLAS bug. The cuBLAS bmm shape at the failing seq=512K / 16-shard config is tiny (batch_count=32768, M=1, K=8, N=2048) and works in isolation. The crash is a downstream symptom of an int32 pointer-offset overflow in the upstream ``scatter2scatter`` Triton kernel during the up-projection, surfaced at the next CUDA-sync point (the bmm). Diagnosis (verified by inserting a ``torch.cuda.synchronize()`` immediately after the up-projection's scatter2scatter — that sync itself raises "an illegal memory access was encountered", proving the fault is upstream of the bmm): The Triton kernel computes output pointer offsets as ``Y_ptr + M_block * stride_ym + N_block * stride_yn`` with int32 ``M_block`` / ``stride_ym``. At seq=524288 / shards=16 the up-projection's output is ``[L_scattered=262144, y_dim=2*INTERMEDIATE=16384]`` = ``2**32`` elements; the trailing rows whose ``M_block * stride_ym`` overflows int32 have their masked stores silently drop (rows come back as zeros) or land at bogus pointers, which then trips a delayed ``CUDA illegal memory access`` that the next kernel surfaces. Workaround at the smallest scope appropriate to the actual root cause (NOT at parallel_experts.py:72, which is downstream): wrap ``kernels.ops.scatter2scatter`` with ``_scatter2scatter_int32_safe`` and route both call sites (``ParallelLinear.forward`` and ``ParallelLinear.backward``) through it. The wrapper: * Fast path (common case): when ``L_scattered * y_dim < 2**31``, dispatches a single direct kernel call — no overhead vs the pre-fix code. Verified at seq=524288 / shards=64: 36741 tokens/s post-fix vs ~37512 tokens/s pre-fix (within noise, no regression). * Slow path: when the output would overflow AND ``y_grouped=True``, allocates the full output and chunks along the L_scattered axis. Each sub-call writes to ``out[chunk_start:chunk_end]`` with the matching sei / ssi slice; the chunk size is the largest BLOCK_M-aligned row count keeping ``rows * y_dim < 2**31``. The chunked path drops into ``kernels.ops.scatter2scatter_compileable`` directly to bypass the high-level wrapper's ``sorted_scattered_idxs.size(0) == X.size(0) * k`` assertion that only holds for full calls. * When ``x_grouped=True`` (the down-proj backward), X is sliced in lockstep so the kernel's ``M_in_idx = M_block`` correctly reads ``X_chunk[0..chunk_size-1]``. When ``x_grouped=False`` (the up-proj forward) X stays full because the kernel indexes X via global ``M_idx // FAN_OUT`` from the per-position ``sorted_scattered_idxs`` values. * For ``y_grouped=False`` at overflow scale, the wrapper hard-raises ``RuntimeError`` — the kernel uses per-position scattered indices as output row indices so the wrapper cannot tile that case safely; the kernel itself needs an int64 pointer-arithmetic fix before that path is callable at this scale. Production paths today are all ``y_grouped=True`` so this branch is unreachable in the bench. Silent corruption is strictly worse than a clear raise. * Includes ``assert L_scattered % chunk_rows == 0`` for the ``x_grouped=False`` chunked path, since the kernel's ``M_boundary_mask`` uses the full (unchunked) X size and a partial last chunk would let the final tile read past sei_chunk / ssi_chunk. The assertion holds for all realistic power-of-2 shapes and fires loudly if a future caller hits a non-aligned one. The ``x_grouped=True`` chunked path is naturally bounded because X is chunked in lockstep. Before / after on the bench config: * pre-fix: CUBLAS_STATUS_EXECUTION_FAILED (no result) * post-fix: 10084 ms/iter, 51989 tokens/s, peak 64.16 GiB (matches the previously-fastest non-failing rows of the s=64 / s=256 sweep; s=16 was the predicted fastest row that the bug had been hiding) Constraints honoured: no changes to ``kernels.ops.scatter2scatter`` or any other Triton kernel; no public-API change on ``parallel_experts.py``; scope confined to scattermoe-lora's ParallelLinear; common-case fast path untouched. The LoRA-path counterpart (``parallel_linear_lora.py`` → ``scatter2scatter_lora``) has the same architectural risk but is not exercised by the failing bench config and is left for follow-up. Signed-off-by: Wing Lian test(scattermoe-lora): enable large-batch repro tests now the fix has landed Remove the ``pytest.mark.skip`` marker added in the ``repro CUBLAS_STATUS_EXECUTION_FAILED`` commit. The fix in the previous ``work around cuBLAS large-batch_count failure`` commit provides ``_scatter2scatter_int32_safe`` and the matching ``_SCATTER2SCATTER_INT32_LIMIT`` constant referenced by these tests, so the three tests now run and guard the fix going forward: * ``test_int32_safe_wrapper_matches_direct_call_below_threshold`` — fast-path equivalence (no overhead in the common case). * ``test_int32_safe_wrapper_no_corruption_at_overflow_shape`` — chunked slow-path correctness at the bench shape. * ``test_parallel_linear_long_seq_routing_combination`` — end-to-end smoke through ``ScatterMoEGatedMLP.forward`` shape sequence at seq=524288 / shards=16. All three pass on CUDA hardware; they self-skip when CUDA is unavailable. Signed-off-by: Wing Lian * feat(scattermoe-lora): add INT64_INDICES tl.constexpr to dense scatter2scatter The Triton scatter2scatter kernel computes output pointer offsets as ``Y_ptr + M_block * stride_ym + N_block * stride_yn`` where M_block / M_idx are int32 by default. At seq=512K with coarse shards the ``L_scattered * y_dim`` product exceeds 2**31 elements and the int32 arithmetic overflows; PR #3667 worked around this by chunking the call along the L_scattered axis when y_grouped=True, but that workaround doesn't cover y_grouped=False (raises) or the LoRA-path kernels. Add an ``INT64_INDICES: tl.constexpr = False`` knob to the dense ``_scatter2scatter`` kernel signature. When True, the M_block range and the scattered-index lookup ``M_idx`` are cast to int64 before they enter the pointer-offset multiplication, so all downstream pointer arithmetic propagates int64. Strides themselves stay as the kernel sees them (coming from ``tensor.stride()`` they're already int64 at the Python level); only the *index* values change type. Triton will JIT a separate variant per constexpr value, so the existing int32 fast path is unaffected. The wrapper-level auto-dispatch (compute ``needs_int64`` from tensor sizes and forward to the kernel) lands in a follow-up commit; this commit just exposes the constexpr and a Python-side ``int64_indices`` kwarg on ``scatter2scatter`` / ``scatter2scatter_compileable``. Signed-off-by: Wing Lian * feat(scattermoe-lora): add INT64_INDICES to LoRA forward + dX kernels (bf16 + MX) Adds the same ``INT64_INDICES: tl.constexpr = False`` knob as the dense kernel to the four LoRA-path scatter2scatter kernels: * ``_scatter2scatter_lora`` — bf16 fused base+LoRA forward * ``_scatter2scatter_lora_dX`` — bf16 fused dX backward * ``_scatter2scatter_lora_mx`` — MXFP4 fused base+LoRA forward * ``_scatter2scatter_lora_dX_mx`` — MXFP4 fused dX backward The cast pattern matches the dense kernel: when ``INT64_INDICES=True``, the per-launch ``M_block`` range and the scattered ``M_idx`` lookup are cast to int64 before they enter the ``M_*_idx * stride_*m`` pointer arithmetic. That promotes the multiplication to int64 and prevents the silent overflow at ``L_scattered * y_dim >= 2**31`` that the chunking workaround on the dense path was guarding against. The Python-side wrappers (``scatter2scatter_lora``, ``scatter2scatter_lora_dX``, ``scatter2scatter_lora_mx``, ``scatter2scatter_lora_dX_mx``) gain an ``int64_indices: bool = False`` kwarg and forward it to the kernel via the constexpr. Auto-dispatch from tensor sizes lands in a follow-up commit. PR #3667's chunking workaround only covered the bf16 dense forward; the LoRA path had the same architectural risk and wasn't covered. With these constexprs in place and the wrapper-side dispatch coming next, the kernel itself becomes int64-safe for all five variants and the chunking wrapper can be retired. Signed-off-by: Wing Lian * feat(scattermoe-lora): add INT64_INDICES to group_bwd_lora kernels Adds ``INT64_INDICES: tl.constexpr = False`` to the three LoRA gradient kernels that index into the grouped M dimension: * ``_group_bwd_lora`` — non-split LoRA-grad kernel (used by autotune-collector mocks; kept in sync for telemetry / future callers) * ``_group_bwd_lora_split`` — split dA/dB kernel that the public ``group_bwd_lora`` wrapper actually dispatches today * ``_group_bwd_lora_fused`` — fused gather + dA/dB kernel used by the LoRA path in ``parallel_linear_lora.py`` In each kernel, when ``INT64_INDICES=True`` we cast: - the per-expert ``start_idx`` / ``end_idx`` (and the fused kernel's ``real_*`` variants) to int64 on load, - ``M_block = tl.arange(0, BLOCK_M)`` to int64 so the per-iter ``M_idx = start_idx + i * BLOCK_M + M_block`` propagates int64, - and (in the fused kernel) ``scatter_idx`` from sorted-index lookups to int64 so ``scatter_idx * stride_dym`` and the ``X_token_idx = scatter_idx // FAN_OUT`` arithmetic stay int64. Strides themselves stay as the kernel receives them (already int64 at the Python level via ``tensor.stride()``). Triton JITs a separate variant per constexpr value, so the int32 fast path is unchanged. Python wrappers (``group_bwd_lora`` and ``group_bwd_lora_fused``) gain an ``int64_indices: bool = False`` kwarg that forwards to the kernel. Wrapper-level auto-dispatch from tensor sizes lands in the next commit. Signed-off-by: Wing Lian * feat(scattermoe-lora): auto-dispatch INT64_INDICES based on tensor sizes Adds ``_needs_int64_indices(*tensors)`` in ``parallel_experts.py``: True iff any input/output tensor's ``numel() >= 2**31 - 1``. That's a sufficient condition for the kernel's ``M_idx * stride_*m`` pointer arithmetic to overflow int32 somewhere in the buffer. Wires the result through the autograd Functions: * ``ParallelLinear`` (``parallel_experts.py``): forward computes ``needs_int64 = (L_scattered * y_dim) >= INT_MAX or _needs_int64_indices(x)`` and forwards via the new ``int64_indices`` kwarg on ``_scatter2scatter_int32_safe``. The wrapper's fast path now passes ``int64_indices`` through to ``kernels.ops.scatter2scatter`` so the kernel takes the int64 path at overflow scale. The wrapper also adds a new branch above the chunking path that routes directly to the int64 kernel when ``int64_indices=True`` is requested — notably this covers the y_grouped=False overflow case that the chunking workaround used to raise on. Backward follows the same pattern using ``L_scattered * K`` for the dX-axis bound. * ``ScatterMoELoRA`` (``parallel_linear_lora.py``): forward computes ``needs_int64`` from ``L_scattered * N`` and forwards to ``scatter2scatter_lora`` / ``scatter2scatter_lora_mx``. Backward computes a single ``needs_int64_bwd`` from ``M_total * max(N, K)`` (covering both the dX and the dA/dB kernels' index ranges) and forwards to ``group_bwd_lora`` / ``group_bwd_lora_fused`` and to the dX kernels (bf16 + MX, fused and non-fused). The auto-dispatch is cheap (one ``Tensor.numel()`` per check) and Triton JITs a separate kernel variant per constexpr value, so the int32 fast path is unaffected for small/medium shapes. Signed-off-by: Wing Lian * test(scattermoe-lora): int32-vs-int64 parity and overflow correctness Adds ``tests/integrations/test_scattermoe_lora_int64_indices.py`` covering two properties of the new INT64_INDICES path: * **Bitwise parity at non-overflow shapes.** For each of the modified kernels, ``INT64_INDICES=False`` and ``INT64_INDICES=True`` compute the same MMA in the same accumulation order — only the index *type* changes. The tests assert ``torch.equal`` between the two variants for the dense forward (both y_grouped=True and y_grouped=False), the LoRA forward, and the LoRA dX backward. For ``_group_bwd_lora_split`` the assertion is bitwise; for ``_group_bwd_lora_fused`` it's ``torch.allclose`` within bf16 tolerance because that kernel uses ``tl.atomic_add`` whose ordering is non-deterministic across launches (so bit-equality is not achievable between any two runs of the same variant, let alone across variants). * **Overflow correctness at the failing bench shape.** At L_scattered=262144 / y_dim=16384 (2**32 element output), the ``INT64_INDICES=True`` kernel populates every row of the output (including rows past the int32 overflow boundary) and matches the chunked workaround within a generous bf16 tolerance. A second bench-shape test runs the real ``ParallelLinear`` forward and uses a monkeypatched spy on ``scatter2scatter_compileable`` to assert the auto-dispatcher routes through the *direct* int64 kernel call (one launch) and **not** the chunking workaround (>=2 launches). Also folds in a kernel-side fix that the parity tests caught: the group_bwd_lora kernels' ``if E_idx == 0: start_idx = 0`` branch produced a plain int32 zero in Triton, which clashes with the int64 ``start_idx`` produced by the else-branch under ``INT64_INDICES=True``, firing ``AssertionError: Mismatched type for start_idx between then block (int32) and else block (int64)`` at compile. Switching the zero-initialisation to ``tl.zeros([], dtype=tl.int64/tl.int32)`` keeps both branches' types consistent. The bench-shape tests are skipped when free GPU memory is below 80 GiB. Signed-off-by: Wing Lian * bench(scattermoe-lora): int64-vs-int32 indexing overhead Adds ``tests/integrations/kernels/scattermoe_lora/bench_int64_kernel.py``, a stand-alone script (not pytest) that times the dense ``kernels.ops.scatter2scatter`` at three representative shapes and reports ms/iter for both ``INT64_INDICES=False`` (int32 fast path) and ``INT64_INDICES=True`` (int64 safe path): * **small** — seq=8K, top_k=8, hidden=2048, N=2048 (auto_int64=False) * **medium** — seq=128K, top_k=8, hidden=2048, N=2048 (auto_int64=False) * **overflow** — seq=512K with 16 shards → L_scattered=262144, N=16384 (auto_int64=True; the previously-failing bench config) At overflow shapes the int32 path is silently incorrect, so the int32 column is replaced by the chunked workaround from PR #3667 as the apples-to-apples baseline. Results land in ``bench_int64_kernel_results.md`` next to the script.

Signed-off-by: Wing Lian refactor(scattermoe-lora): deprecate _scatter2scatter_int32_safe chunking now that kernel is int64-safe PR #3667's ``_scatter2scatter_int32_safe`` chunking wrapper was the minimum-scope fix for the int32 pointer-overflow at the failing bench config: it tiled the call along the L_scattered axis to keep each sub-launch's ``rows * y_dim < 2**31``. With the kernel-level ``INT64_INDICES`` constexpr now landing on every relevant scatter2scatter family kernel and the wrapper-level auto-dispatch plumbed through both ``parallel_experts.py`` and ``parallel_linear_lora.py``, the chunking workaround is redundant — the kernel handles the overflow itself in a single launch. Removes from ``parallel_experts.py``: * ``_scatter2scatter_int32_safe`` and its 160-line chunking loop * ``_SCATTER2SCATTER_INT32_LIMIT`` and ``_SCATTER2SCATTER_BLOCK_M`` constants used only by the chunking path * the ``RuntimeError`` raise for ``y_grouped=False`` at overflow scale — the int64 kernel handles that case directly Routes ``ParallelLinear.forward`` / ``.backward`` straight to ``kernels.ops.scatter2scatter`` with ``int64_indices=needs_int64``. The bench config (seq=524288, 16 shards → L_scattered=262144, y_dim=16384, output=2**32 elements) now goes through a single int64 kernel launch and matches the bench-recorded perf (79.6 ms/iter vs. the chunked workaround's 80.0 ms/iter — slightly *faster* because it eliminates the per-chunk launch overhead). The PR #3667 repro tests are retained as regression guards and updated to call the new direct-kernel path: * ``test_scatter2scatter_below_threshold_no_overhead`` (renamed from ``test_int32_safe_wrapper_matches_direct_call_below_threshold``) asserts INT64_INDICES=False vs True is bit-identical at non- overflow shapes — guards the int32 fast path. * ``test_scatter2scatter_no_corruption_at_overflow_shape`` (renamed from ``test_int32_safe_wrapper_no_corruption_at_overflow_shape``) asserts the int64 kernel populates rows past the int32 overflow boundary — guards the kernel-level overflow fix. * ``test_parallel_linear_long_seq_routing_combination`` is unchanged; it runs ``parallel_linear`` end-to-end at the bench shape and asserts no all-zero rows / no NaNs — guards the auto-dispatch wiring. The new ``test_parallel_linear_overflow_takes_int64_kernel_path`` in ``test_scattermoe_lora_int64_indices.py`` is also updated to monkey- patch ``scatter2scatter_compileable`` and assert the single launch sets ``int64_indices=True``, which directly verifies the auto- dispatch verdict at the failing bench shape. Signed-off-by: Wing Lian * chore(scattermoe-lora): pre-commit fixups for INT64 indices commits * ruff format pass on the four touched files (line-wrapping only, no functional changes). * ``parallel_linear_lora.py``: replace the one-line conditional ``N_dim = expert_weights.N if is_mx else expert_weights.size(-1)`` with an explicit if/else and ``# type: ignore[union-attr]`` on each branch — mypy can't narrow ``Union[Tensor, MXWeights]`` through a ternary, but does respect the explicit branches enough to need the ignore only on the offending attribute access.

The bench now reports int32 vs int64 timings only; the overflow row shows only int64 since the int32 kernel is silently incorrect there. Signed-off-by: Wing Lian * test(scattermoe-lora): add small-shape int64 overflow tests (run on L40S/24 GiB) The two bench-shape overflow tests above need ~80 GiB free and skip on the Modal CI L40S 48 GiB runner, so the actual overflow path the kernel fix targets was not exercised on CI. The new ..._small variants repro the same property at the smallest shape that still straddles the int32 boundary: L_scattered * y_dim = 2**32 (2x past 2**31, guaranteed overflow without int64_indices=True), with E=4, K=256, y_dim=4096 so W is ~8 MiB and the only big allocation is the ~8 GiB scatter output. Gated at 12 GiB free to leave headroom for pytest-xdist workers on 48 GiB devices. * fix(scattermoe-lora): bump _SMALL_E so int64-overflow topk is valid _SMALL_TOP_K=8 with _SMALL_E=4 makes torch.topk(logits[T,4], k=8) raise 'selected index k out of range', skipping the two _small overflow tests. The shape invariant L_scattered*y_dim=2**32 (T=131072, y_dim=4096) requires top_k=8, so E must be >= 8. * perf(scattermoe-lora): bucket M in autotune key to dedupe sweeps The 7 multi-config @triton.autotune kernels in lora_ops.py keyed on ["M", "N", "K"]. M = X.size(0) (or DY.size(0)) scales with batch*seq*top_k, so any seqlen variation triggers a fresh 30-60 config sweep per step until the cache happens to cover every realized M. With N, K model-fixed this was the only churning dimension. Add a phantom M_BUCKET arg to each kernel signature and switch the autotune key to ["M_BUCKET", "N", "K"]. The kernel still runs on the real M (loop bounds + masks unchanged); only the cache lookup is bucketed to the next multiple of _M_BUCKET_GRANULARITY=1024. No padding, no wasted FLOPs. autotune_collector._KEY_NAMES tracks the renamed key so telemetry matches what's actually in the .cache dict. Tests: - New test_scattermoe_lora_m_bucket.py pins both directions: same-bucket M values produce one cache entry, distinct-bucket M values produce two. - Updated telemetry test assertions for the renamed key. - Existing scattermoe-lora suite (62 tests) + int64 indices (10 tests) + telemetry (13 tests) all pass unchanged. --------- Signed-off-by: Wing Lian --- .../kernels/autotune_collector.py | 8 +- .../libs/scattermoe_lora/kernels/lora_ops.py | 163 ++++- .../libs/scattermoe_lora/kernels/ops.py | 12 +- .../libs/scattermoe_lora/parallel_experts.py | 41 ++ .../scattermoe_lora/parallel_linear_lora.py | 28 + .../scattermoe_lora/bench_int64_kernel.py | 229 +++++++ .../bench_int64_kernel_results.md | 15 + ...test_parallel_experts_large_batch_repro.py | 289 +++++++++ .../test_scattermoe_lora_int64_indices.py | 581 ++++++++++++++++++ .../test_scattermoe_lora_m_bucket.py | 118 ++++ .../test_scattermoe_autotune_telemetry.py | 4 +- 11 files changed, 1453 insertions(+), 35 deletions(-) create mode 100644 tests/integrations/kernels/scattermoe_lora/bench_int64_kernel.py create mode 100644 tests/integrations/kernels/scattermoe_lora/bench_int64_kernel_results.md create mode 100644 tests/integrations/kernels/scattermoe_lora/test_parallel_experts_large_batch_repro.py create mode 100644 tests/integrations/kernels/scattermoe_lora/test_scattermoe_lora_int64_indices.py create mode 100644 tests/integrations/kernels/scattermoe_lora/test_scattermoe_lora_m_bucket.py diff --git a/src/axolotl/integrations/kernels/autotune_collector.py b/src/axolotl/integrations/kernels/autotune_collector.py index bdb5e030e4..92e0dbe2d5 100644 --- a/src/axolotl/integrations/kernels/autotune_collector.py +++ b/src/axolotl/integrations/kernels/autotune_collector.py @@ -21,15 +21,17 @@ ("group_bwd_lora_fused", "_group_bwd_lora_fused"), ] -# The autotune key declared on every kernel: key=["M", "N", "K"] -_KEY_NAMES: list[str] = ["M", "N", "K"] +# The autotune key declared on every kernel: key=["M_BUCKET", "N", "K"]. +# M_BUCKET is the seqlen-bucketed M (see _bucket_m in lora_ops.py) so cache +# entries don't churn with every distinct M. +_KEY_NAMES: list[str] = ["M_BUCKET", "N", "K"] def _parse_key_tuple(key_tuple: tuple) -> dict[str, Any]: """Turn the autotune cache key tuple into a labelled dict.

Eager-mode behavior is bit-identical when the new cfg.fused_attn_kernel flag is unset. Changes ------- * New ``cfg.fused_attn_kernel: bool | None`` (default None / off). When set, replaces ``q_norm + apply_rotary_pos_emb`` (and the matching K path) with a single fused RMSNorm+RoPE Triton kernel launch. Currently wired for ``qwen3``, ``qwen3_moe``, ``qwen3_5``, and ``qwen3_5_moe`` model_config_types. Llama4 is out of scope (complex freqs_cis + Llama4TextL2Norm post-RoPE — separate kernel). * Kernel ``UNIT_OFFSET: tl.constexpr`` flag added to the forward + backward Triton kernels for Qwen3.5's Gemma-style ``(1.0 + weight)`` RMSNorm. Default ``False`` keeps Gemma 4 / Qwen3 / Qwen3-MoE bit-identical to before. Threaded through the triton_op + register_autograd plumbing. * Refactors ``fused_rms_norm_rope`` / ``fused_rms_norm_noscale`` to ``torch.library.triton_op`` + ``register_autograd`` so they trace under ``torch.compile(fullgraph=True)``. Validated: 1 Dynamo frame, 0 graph breaks. On sm_120 the compile path composes to +9.2% combined, −33% peak memory. On sm_86 the surrounding Inductor-generated kernels regress — leave ``torch_compile: false`` there; schema description documents the per-arch recommendation. * Liger Qwen-VL auto-default: when ``cfg.liger_rope is None`` and model_config_type is one of qwen2_vl/qwen2_5_vl/qwen3_vl (+ ``_text`` variants), pass ``rope=True`` so upstream's fused m-rope kernel is actually installed. Previously the plugin overrode the upstream default to None, silently skipping the kernel. * Patch-ordering fix: ``_apply_self_attention_lora_patch`` now runs before ``_apply_model_specific_patches`` in ``apply_pre_model_load_patches``. ``patch_self_attn_lora`` reads ``inspect.getsource`` of the attention class' forward, so any patch that replaces ``Attention.forward`` must run *after* the source-rewrite step. The wrong order also silently broke Gemma 4 + ``lora_qkv_kernel`` — pinned by ``TestPatchManagerOrdering`` and a fused-first trip-wire. Tests ----- * Per-model parity + backward grad flow for Qwen3, Qwen3-MoE, Qwen3.5, Qwen3.5-MoE (full-attention layers only; linear_attention layers stay on the stock GatedDeltaNet path). * Kernel ``UNIT_OFFSET=True`` parity vs from-scratch reference + bwd parity vs torch-eager + ``torch.compile(fullgraph=True)`` parity. * ``torch.compile(fullgraph=True)`` parity for the no-offset path. * Liger Qwen-VL auto-default for all 6 model_config_types; explicit ``False`` is respected. * Patch idempotency (double-apply is a no-op). * Transformers signature contract — pins the stock attention forward argument names so future drift trips loudly at test time. * Gradient-checkpointing composition (Qwen3 + ``gradient_checkpointing_enable``). * Flash-Attention 2 composition (skip-if-unavailable). * LoRA + fused composition on Qwen3 / Qwen3.5 / Qwen3.5-MoE, with fused-first reverse-order trip-wires that catch the original ordering bug if anyone re-introduces it. A pre-existing upstream-drift xfail in ``test_gemma4_fused_attn.py`` documents Gemma 4 + ``lora_qkv_kernel`` being broken in transformers 5.8.1 (new ``shared_kv_states: dict[str, ...]`` signature drift in QKV_PATCHES). Out of scope for this PR; flips to XPASS when patched. Post-review fixes ----------------- * ``_resolve_norm_module``: PEFT ``ModulesToSaveWrapper`` stores ``active_adapter`` as ``list[str]`` (e.g. ``["default"]``), not a string. The prior ``isinstance(adapter, str)`` check silently returned the frozen ``original_module`` for every real-PEFT case. Switched to iterating ``active_adapters`` (with ``active_adapter`` fallback) across all 4 patches. Added a direct unit-test plus an end-to-end test that drives real ``peft.get_peft_model(modules_to_save=["q_norm","k_norm"])`` and asserts the helper returns the trainable adapter weight. * ``cfg.fused_attn_kernel`` unsupported-model warning: moved out of the Pydantic ``model_validator(mode="before")`` (which ran *before* ``normalize_config()`` had derived ``model_config_type``, so it silently no-op'd on normal YAML input) into a new ``PatchManager._warn_if_fused_attn_unsupported`` staticmethod invoked from ``_apply_model_specific_patches``, where ``model_config_type`` is guaranteed set. Added a source-line guard that the helper stays wired. * address coderabbit comments * improve bwd pass throughput * feat(qwen3-vl): add fused attention patch * test: capture fused attention logs from concrete loggers * ci: rerun tests --------- Co-authored-by: Wing Lian --- docs/optimizations.qmd | 11 + examples/qwen3/8b-lora-fused-attn.yaml | 44 ++ src/axolotl/core/builders/base.py | 12 + src/axolotl/integrations/liger/args.py | 11 +- src/axolotl/integrations/liger/plugin.py | 15 +- src/axolotl/kernels/autotune_telemetry.py | 136 ++++++ src/axolotl/kernels/gemma4_fused_rope.py | 371 ++++++++------- src/axolotl/loaders/patch_manager.py | 79 +++- .../monkeypatch/models/qwen3/__init__.py | 0 .../monkeypatch/models/qwen3/fused_attn.py | 117 +++++ .../monkeypatch/models/qwen3_5/fused_attn.py | 133 ++++++ .../models/qwen3_5_moe/__init__.py | 0 .../models/qwen3_5_moe/fused_attn.py | 135 ++++++ .../monkeypatch/models/qwen3_moe/__init__.py | 0 .../models/qwen3_moe/fused_attn.py | 121 +++++ .../monkeypatch/models/qwen3_vl/__init__.py | 0 .../monkeypatch/models/qwen3_vl/fused_attn.py | 121 +++++ src/axolotl/utils/schemas/config.py | 19 + .../test_liger_qwen_vl_rope_default.py | 124 +++++ .../test_fused_rope_autotune_telemetry.py | 168 +++++++ .../kernels/test_gemma4_fused_rope_compile.py | 66 +++ .../test_gemma4_fused_rope_unit_offset.py | 238 ++++++++++ tests/monkeypatch/test_gemma4_fused_attn.py | 155 +++++-- tests/monkeypatch/test_qwen3_5_fused_attn.py | 424 ++++++++++++++++++ tests/monkeypatch/test_qwen3_fused_attn.py | 283 ++++++++++++ .../test_qwen3_fused_attn_defensive.py | 375 ++++++++++++++++ .../test_qwen3_fused_attn_robustness.py | 206 +++++++++ tests/monkeypatch/test_qwen3_vl_fused_attn.py | 168 +++++++ 28 files changed, 3293 insertions(+), 239 deletions(-) create mode 100644 examples/qwen3/8b-lora-fused-attn.yaml create mode 100644 src/axolotl/kernels/autotune_telemetry.py create mode 100644 src/axolotl/monkeypatch/models/qwen3/__init__.py create mode 100644 src/axolotl/monkeypatch/models/qwen3/fused_attn.py create mode 100644 src/axolotl/monkeypatch/models/qwen3_5/fused_attn.py create mode 100644 src/axolotl/monkeypatch/models/qwen3_5_moe/__init__.py create mode 100644 src/axolotl/monkeypatch/models/qwen3_5_moe/fused_attn.py create mode 100644 src/axolotl/monkeypatch/models/qwen3_moe/__init__.py create mode 100644 src/axolotl/monkeypatch/models/qwen3_moe/fused_attn.py create mode 100644 src/axolotl/monkeypatch/models/qwen3_vl/__init__.py create mode 100644 src/axolotl/monkeypatch/models/qwen3_vl/fused_attn.py create mode 100644 tests/integrations/test_liger_qwen_vl_rope_default.py create mode 100644 tests/kernels/test_fused_rope_autotune_telemetry.py create mode 100644 tests/kernels/test_gemma4_fused_rope_compile.py create mode 100644 tests/kernels/test_gemma4_fused_rope_unit_offset.py create mode 100644 tests/monkeypatch/test_qwen3_5_fused_attn.py create mode 100644 tests/monkeypatch/test_qwen3_fused_attn.py create mode 100644 tests/monkeypatch/test_qwen3_fused_attn_defensive.py create mode 100644 tests/monkeypatch/test_qwen3_fused_attn_robustness.py create mode 100644 tests/monkeypatch/test_qwen3_vl_fused_attn.py diff --git a/docs/optimizations.qmd b/docs/optimizations.qmd index 621c2c0bcd..60a011b415 100644 --- a/docs/optimizations.qmd +++ b/docs/optimizations.qmd @@ -73,6 +73,17 @@ Provides efficient Triton kernels to improve training speed and reduce memory us - **Learn more:** [Custom Integrations - Liger Kernels](custom_integrations.qmd#liger-kernels) +### Fused RMSNorm + RoPE (Qwen3 / Qwen3-MoE / Qwen3.5 / Qwen3.5-MoE / Qwen3.6 dense / Qwen3.6-MoE) + +Replaces the per-layer `q_norm + apply_rotary_pos_emb` (and matching K path) with a single Triton kernel launch on the full-attention layers.

Wing Lian Date: Fri, 29 May 2026 01:15:48 -0400 Subject: [PATCH 1333/1405] test(scattermoe-lora): skip on CUDA OOM under xdist contention (#3689) [skip-ci] When the suite runs under pytest-xdist, multiple workers race for the same physical GPU's memory budget. A test that fits comfortably in isolation can OOM purely because peer workers are already holding most of VRAM (observed: 8 workers each holding ~44 GiB on a 44 GiB card). Add a conftest in tests/integrations/kernels/scattermoe_lora/ that hooks pytest_runtest_call and converts torch.OutOfMemoryError into a skip. Real correctness bugs still surface as failures since they raise asserts / typed exceptions, not OOM.

The patch under test (strip dead entries before ``kernelize()`` runs) does the right thing either way; broaden the expected-crash assertion so the test reflects current upstream behavior. * 30 min timeout * fix(activation-offload): drop monkey-patched __enter__ now that TRL 1.5.1 ships upstream fix TRL 1.5.1 implements huggingface/trl#5730 natively — ``OffloadActivations`` now has its own ``__enter__`` that clears tracker / stashes between steps, **plus** two things the axolotl backport never had: - ``self.tensor_id = 0`` reset (without this, the tensor_id counter accumulates across steps; harmless on its own but skews the ``fwd_stash`` eviction window). - ``torch.cuda.empty_cache()`` when bitsandbytes is loaded — flushes the BNB allocator between steps so its compute / optimizer-state buffers don't accumulate as live storage. TRL 1.5.1 also adds a ``__exit__`` that syncs the offload streams (``s0``, ``s1``) before the parent cleanup runs. The axolotl backport only overrode ``__enter__``, so ``__exit__`` was inherited correctly either way. Once we bumped TRL 1.1.0 → 1.5.1 (transformers 5.9 bundle), the monkey-patch became strictly worse than upstream — it shadowed the better ``__enter__``, dropping the ``tensor_id`` reset and the BNB ``empty_cache``. Combined with cu130's stricter cross-stream lifetime checks, this surfaced as XID 43 (driver-killed CUDA channel) during ``test_activation_offloading[lora]``, followed by every subsequent test failing at ``torch.manual_seed(42)`` because the CUDA context was permanently poisoned. Drop the patch and the wrapper — upstream is now the source of truth, per the existing TODO in this file. --- .github/workflows/tests.yml | 2 +- VERSION | 2 +- pyproject.toml | 4 ++-- .../mixins/activation_checkpointing.py | 19 ------------------- tests/monkeypatch/test_gemma4_kernelize.py | 2 +- 5 files changed, 5 insertions(+), 24 deletions(-) diff --git a/.github/workflows/tests.yml b/.github/workflows/tests.yml index 1adc76bf61..cc5e0bd4e3 100644 --- a/.github/workflows/tests.yml +++ b/.github/workflows/tests.yml @@ -72,7 +72,7 @@ jobs: exclude: - python_version: "3.14" pytorch_version: "2.9.1" - timeout-minutes: 25 + timeout-minutes: 30 steps: - name: cleanup node diff --git a/VERSION b/VERSION index b08b47558c..52fc5b872a 100644 --- a/VERSION +++ b/VERSION @@ -1 +1 @@ -0.16.2.dev0 +0.17.0.dev diff --git a/pyproject.toml b/pyproject.toml index 0c09c30a5d..01cac4b8b0 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -17,10 +17,10 @@ dependencies = [ "huggingface_hub>=1.1.7", "peft>=0.19.1,<0.20.0", "tokenizers>=0.22.1", - "transformers==5.8.1", + "transformers==5.9.0", "accelerate==1.13.0", "datasets>=4.8.4,<4.9.0", - "trl==1.1.0", + "trl==1.5.1", "hf_xet==1.4.3", "kernels==0.13.0", "trackio>=0.16.1", diff --git a/src/axolotl/core/trainers/mixins/activation_checkpointing.py b/src/axolotl/core/trainers/mixins/activation_checkpointing.py index dd892bebce..b61c45feed 100644 --- a/src/axolotl/core/trainers/mixins/activation_checkpointing.py +++ b/src/axolotl/core/trainers/mixins/activation_checkpointing.py @@ -22,25 +22,6 @@ LOG = get_logger(__name__) -# TODO(#3638): drop once TRL pin includes huggingface/trl#5730.

Try the 2.12 anchor first; fall back to the 2.11 anchor so the patch keeps working against both torch versions in our test matrix. init_unsharded_param uses the same kwarg-style call in both 2.11 and 2.12, so its anchor is untouched. * fix(fsdp2-qlora): match init_unsharded_param anchor for torch 2.12 torch 2.12 hoisted the unsharded-param construction out of the first-all-gather `else:` branch up to method-body level, so the 2.11 anchor (8-space, inside else) no longer matched and the patch silently no-op'd. This left bitsandbytes Params4bit unreconstructed under FSDP2, surfacing as `mat1 and mat2 shapes cannot be multiplied (... 1x36864)` in QLoRA training.

Run 20 steps with seed=42 to make the loss deterministic (2.189-2.191 spread), and tighten the threshold to 2.5. * fix(optimizers): support torch 2.11 graph health-check rename in ADOPT torch 2.11 renamed Optimizer._cuda_graph_capture_health_check to _accelerator_graph_capture_health_check (2.12 re-added the old name as an alias). ADOPT called the old name, so it raised AttributeError under torch 2.11 — surfaced by bumping the docker-e2e row from 2.9.1 to 2.11.0. Resolve whichever name exists, preferring the new one.

On the pinned transformers 5.9, any Gemma4 model with `num_kv_shared_layers > 0` (e.g. gemma-4-E2B vision) raised `AttributeError: 'Gemma4TextAttention' object has no attribute 'kv_shared_layer_index'` once execution reached a shared layer. Derive the read/store key from whichever attribute the installed transformers exposes, keeping compatibility with both the old and new APIs. Add a fused-attn regression with `num_kv_shared_layers > 0` so the shared-KV branch is actually exercised (existing tests defaulted to 0). --- .../monkeypatch/models/gemma4/fused_attn.py | 17 ++++- tests/monkeypatch/test_gemma4_fused_attn.py | 71 +++++++++++++++++++ 2 files changed, 86 insertions(+), 2 deletions(-) diff --git a/src/axolotl/monkeypatch/models/gemma4/fused_attn.py b/src/axolotl/monkeypatch/models/gemma4/fused_attn.py index 4f4e8f5f2d..a4f15207f8 100644 --- a/src/axolotl/monkeypatch/models/gemma4/fused_attn.py +++ b/src/axolotl/monkeypatch/models/gemma4/fused_attn.py @@ -31,6 +31,19 @@ def _get_shared_kv_states(): return _GEMMA4_SHARED_KV_STORE["store"] +def _shared_kv_read_key(attn): + # transformers >=5.8 keys shared kv by layer_type; older builds used kv_shared_layer_index + if hasattr(attn, "kv_shared_layer_index"): + return attn.kv_shared_layer_index + return attn.layer_type + + +def _shared_kv_store_key(attn): + if hasattr(attn, "kv_shared_layer_index"): + return attn.layer_idx + return attn.layer_type + + def _make_fused_forward(original_forward): """Create a patched forward that uses fused RMSNorm+RoPE kernels.""" @@ -85,7 +98,7 @@ def fused_forward( # ---- K/V path ---- if self.is_kv_shared_layer: - key_states, value_states = shared_kv_states[self.kv_shared_layer_index] + key_states, value_states = shared_kv_states[_shared_kv_read_key(self)] key_states = key_states.to(query_states.device) value_states = value_states.to(query_states.device) else: @@ -124,7 +137,7 @@ def fused_forward( key_states, value_states, self.layer_idx ) if self.store_full_length_kv: - shared_kv_states[self.layer_idx] = key_states, value_states + shared_kv_states[_shared_kv_store_key(self)] = key_states, value_states attention_interface: Callable = eager_attention_forward if self.config._attn_implementation != "eager": diff --git a/tests/monkeypatch/test_gemma4_fused_attn.py b/tests/monkeypatch/test_gemma4_fused_attn.py index 92a07f7aab..db719c4cc7 100644 --- a/tests/monkeypatch/test_gemma4_fused_attn.py +++ b/tests/monkeypatch/test_gemma4_fused_attn.py @@ -170,6 +170,77 @@ def test_reverse_order_skips_lora_rewrite( pass +def _build_kv_shared_config(): + """Hybrid Gemma 4 with ``num_kv_shared_layers > 0`` so the fused shared-KV branch runs.""" + from transformers.models.gemma4.configuration_gemma4 import Gemma4TextConfig + + cfg = Gemma4TextConfig( + vocab_size=128, + hidden_size=64, + intermediate_size=128, + num_hidden_layers=4, + num_kv_shared_layers=2, + num_attention_heads=2, + num_key_value_heads=2, + head_dim=32, + global_head_dim=64, + layer_types=[ + "sliding_attention", + "full_attention", + "sliding_attention", + "full_attention", + ], + sliding_window=64, + max_position_embeddings=2048, + hidden_size_per_layer_input=16, + vocab_size_per_layer_input=128, + rope_parameters={ + "sliding_attention": {"rope_type": "default", "rope_theta": 10000.0}, + "full_attention": { + "rope_type": "proportional", + "rope_theta": 1000000.0, + "partial_rotary_factor": 0.25, + }, + }, + ) + cfg._attn_implementation = "sdpa" + return cfg + + +class TestFusedAttnSharedKV: + """Regression: ``num_kv_shared_layers > 0`` hit the ``kv_shared_layer_index`` key removed in transformers>=5.8.""" + + def test_shared_kv_forward_backward(self, restore_gemma4_attention): + from transformers.models.gemma4.modeling_gemma4 import Gemma4TextModel + + from axolotl.monkeypatch.models.gemma4.fused_attn import ( + patch_gemma4_fused_attn, + ) + + torch.manual_seed(4) + m = Gemma4TextModel(_build_kv_shared_config()).cuda().to(torch.bfloat16).train() + assert any(layer.self_attn.is_kv_shared_layer for layer in m.layers), ( + "test config must exercise at least one kv-shared layer" + ) + + ids = torch.randint(0, 128, (2, 16), device="cuda") + mask = torch.ones(2, 16, dtype=torch.long, device="cuda") + + with torch.no_grad(): + ref = m(input_ids=ids, attention_mask=mask).last_hidden_state.clone() + + patch_gemma4_fused_attn() + out = m(input_ids=ids, attention_mask=mask).last_hidden_state + out.sum().backward() + + assert out.shape == ref.shape + assert torch.isfinite(out).all() + cos_sim = torch.nn.functional.cosine_similarity( + ref.flatten().float(), out.detach().flatten().float(), dim=0 + ) + assert cos_sim > 0.999, f"shared-kv fused vs stock cosine_sim={cos_sim:.6f}" + + class TestFusedAttnSignature: """Pin the fused forward against the live ``Gemma4TextDecoderLayer.forward`` call shape."""

Replace with out.addmm_(X_lora @ A, B, alpha=s): the X_lora @ A intermediate is only [M, rank], no [M, out_features] temp, and the add is fp32-accumulated. Same math, slightly more accurate (fp32 accumulate vs the prior fp16 allocate-then-add), full cuBLAS speed, all hardware. test_matmul_lora switches to an fp32 reference since the kernel no longer mirrors the old fp16 intermediate rounding. * perf(lora-kernels): fuse LoRA_MLP backward dX add via addmm_ The base-path input gradient did dX += grad_gate @ gate_weight_deq, materializing a full [M, hidden] temp before the add. Replace with dX.addmm_(grad_gate, gate_weight_deq): same math, fp32-accumulated, no temp. Halves the peak memory of that step (the temp equals dX in size) at neutral speed; mirrors the matmul_lora forward fix. * perf(sonicmoe-lora): fuse expert weight materialization via baddbmm MoELoRAMaterialize.forward built W_eff = base_weight + scaling * bmm(B,A), allocating a full [E, dim1, dim2] bmm temp plus a second scaling-scaled copy. torch.baddbmm(base_weight, B_3d, A_3d, alpha=scaling) computes it in one fused op. Same math, fp32-accumulated; backward is unchanged (it saves lora_A/lora_B and recomputes, never referencing the delta). Measured (bf16, E=8 4096x4096 r=16): -67% peak memory (805 -> 268 MB) and 1.46x faster (1.07 -> 0.73 ms) on the per-forward weight-materialization path. gradcheck (fp64) still passes. * split up pytests to get long tail of test durations * fix(tests): make HF-throttled tests offline-safe via prefetch + cache Several tests fetched datasets/tokenizers by Hub path at runtime. When the HF Hub throttles (403/429), huggingface_hub retries with backoff (90s-7min per call), inflating the CPU CI legs past the 30-min timeout and failing ~10 tests with HfHubHTTPError. The failing tests simply ran online and weren't covered by the existing `enable_hf_offline` mechanism. - Add session prefetch fixtures for the previously-uncached repos: mistralai/Magistral-Small-2506, Devstral-Small-2505/2507 (tokenizer files only, incl. tekken.json/params.json which `*token*` misses), and trl-lib/math_shepherd. - Decorate the offending tests with `@enable_hf_offline`, and offline-wrap the shared `model`/`tokenizer` builder fixtures (the decorator can't cover pytest fixture setup, where the slow loads happen). - Swap the ebft multi-turn test off Qwen2-0.5B-Instruct (uncached) to the already-prefetched SmolLM2-135M-Instruct; the assertions are chat-template structural, not tokenizer-specific. - Mistral tokenizers can't use offline mode (mistral-common doesn't catch OfflineModeIsEnabled), but it does fall back to local files on a throttle HTTPError. Pass revision=None in the fixtures so that fallback resolves the cached snapshot via refs/main instead of a nonexistent snapshots/main dir. - Fix HFMistralTokenizer.from_pretrained passing cache_dir=str(None)="None", which downloaded tokenizers into a stray ./None dir and bypassed the HF cache (and the prefetch). * fix(tests): prefetch Hub-path datasets via load_dataset for offline loading The previous commit added @enable_hf_offline to dataset-loading tests, but they failed in CI with `ConnectionError: Couldn't reach 'X' on the Hub (OfflineModeIsEnabled)`. snapshot_download only populates the *hub* cache; an offline `load_dataset` resolves via the *datasets* cache, which stays empty. (Locally the tests passed only because that cache was already warm.) Add load_dataset_w_retry (cache-first, else online) and use it for the five datasets the offline tests load by Hub path: mhenrichsen/alpaca_2k_test, argilla/distilabel-intel-orca-dpo-pairs, argilla/ultrafeedback-binarized-preferences-cleaned(-kto), and trl-lib/math_shepherd. Verified by clearing the datasets cache and confirming the autouse fixtures rebuild it and the offline tests pass. * Revert "fix(tests): prefetch Hub-path datasets via load_dataset for offline loading" This reverts commit d95991e6160aeefa8ab0221ef7d33b492d0ea254. * Revert "fix(tests): make HF-throttled tests offline-safe via prefetch + cache" This reverts commit d25b7a178df17149ef9274f84cc989fa0439d6d6. --- .github/workflows/tests.yml | 27 ++++++++++++++----- .../kernels/libs/sonicmoe/lora.py | 7 +++-- src/axolotl/kernels/lora.py | 4 +-- tests/e2e/kernels/test_lora.py | 13 ++++++--- 4 files changed, 34 insertions(+), 17 deletions(-) diff --git a/.github/workflows/tests.yml b/.github/workflows/tests.yml index 888c3e39b9..2d724b644c 100644 --- a/.github/workflows/tests.yml +++ b/.github/workflows/tests.yml @@ -72,6 +72,12 @@ jobs: exclude: -

YB=dY@B) in registers once per output dim-block to avoid materializing it; and the non-fused dX_lora path is a Python per-expert loop with an expert_offsets[e].item() device sync per expert. Both scale badly with the expert count -- and modern MoEs run E>=128. The intermediates are rank-sized ([M*k, R], R~16), so materializing them once is near-free (the split kernel saves only ~2-8 MB across these shapes -- smaller than the dA/dB gradient it produces). Backport the multi-adapter wins to the single-adapter path: - grouped_gram.py: _grouped_gram_kernel + grouped_lora_weight_grads -- dA/dB as recompute-free grouped Gram products over precomputed XA/YB (bit-identical to group_bwd_lora, err 0.0). - ScatterMoELoRA.backward non-fused dA/dB: compute YB, XA once, then grouped-Gram; YB is reused by the non-fused dX_lora. - _compute_lora_input_grad: two grouped scatter2scatter GEMMs (sync-free, single launch each) when routing ids are given, reusing YB; the per-expert loop is kept as a fallback but with one host sync for the whole offset array, not O(E). Before/after, full ScatterMoELoRA fwd+bwd (E>=128, M=4096): fused-dX path (production, #dA/dB only): 1.08-1.15x non-fused path (#dA/dB + #dX_lora): up to 2.2x (Qwen3-MoE, DeepSeek) at +5..30 MB peak (the XA/YB buffers). The dA/dB kernel alone is 2-17x faster. MXFP4 unaffected: dX takes the is_mx branch (scatter2scatter_lora_dX_mx) and never the rewritten non-fused path; dA/dB never touch the (frozen) base, so LoRA grads are bit-identical for an MX base vs its bf16 dequantization at a workload above the fuse-gather threshold (new regression test). #1 (sonicmoe materialize) is already on main via baddbmm. * chore: lint * chore: lint --- .../scattermoe_lora/kernels/grouped_gram.py | 210 ++++++++++++++++++ .../scattermoe_lora/parallel_linear_lora.py | 127 ++++++++--- .../test_mx_lora_grouped_gram.py | 77 +++++++ 3 files changed, 383 insertions(+), 31 deletions(-) create mode 100644 src/axolotl/integrations/kernels/libs/scattermoe_lora/kernels/grouped_gram.py create mode 100644 tests/integrations/kernels/scattermoe_lora/test_mx_lora_grouped_gram.py diff --git a/src/axolotl/integrations/kernels/libs/scattermoe_lora/kernels/grouped_gram.py b/src/axolotl/integrations/kernels/libs/scattermoe_lora/kernels/grouped_gram.py new file mode 100644 index 0000000000..c0b7f0f712 --- /dev/null +++ b/src/axolotl/integrations/kernels/libs/scattermoe_lora/kernels/grouped_gram.py @@ -0,0 +1,210 @@ +# SPDX-License-Identifier: Apache-2.0 +# Copyright (c) Axolotl AI +# Licensed under the Apache License, Version 2.0 + +"""Grouped-Gram LoRA weight gradients (dA/dB) without per-output-block recompute. + +The split kernel in ``lora_ops`` recomputes XA = X@A^T (resp.

Worse, routing all sentinels to expert 0 piles ~half the rows into one bucket -> pathological load imbalance. scattermoe_experts_forward_ep drops the -1 sentinel rows before the GEMMs: runs both projections fully grouped over only the valid routed rows (the compacted routing breaks scatter2scatter's L == X.rows*k fan-out contract) and does the weighted token-combine via index_add_. Output is identical to the masked path since sentinel slots carry weight 0. The deep_ep dispatch now passes the raw -1-tagged routing through; each local kernel handles sentinels its own way (eager/scattermoe skip, grouped_mm masks). scattermoe LoRA fwd+bwd, RTX PRO 6000 (Blackwell), skip vs mask: Qwen3-30B ep2 2.9x/0.67x mem ep4 6.0x/0.37x ep8 10.3x/0.25x Qwen3-235B ep2 2.5x/0.65x ep4 4.9x/0.37x ep8 8.4x/0.24x DeepSeek ep2 2.1x/0.60x ep4 3.9x/0.34x ep8 6.8x/0.23x Validated bit-equivalent to the masked path (fp32 ~1e-7, bf16 ~6-9e-3) on output, dX and LoRA dA/dB for base + LoRA at ep2/ep4. * feat(scattermoe): gpt_oss layout + sm_120 sonicmoe fallback The sonic-moe CUTLASS kernel can't compile on consumer Blackwell (sm_120): its bundled quack GemmSm120 predates the concat_layout arg the dispatcher passes. Make the vendored scattermoe Triton path cover the gap. 1. gpt_oss layout in scattermoe_experts_forward: dispatch on the layout flags and handle the gpt_oss-style experts (is_transposed, not is_concatenated, has_bias) in a dedicated path -- weights are already [E, in, out] (no transpose), gate/up are interleaved ([..., ::2] / [..., 1::2]), per-expert bias is folded into the grouped GEMM, and the activation is the clamped sigmoid-GLU. LoRA fuses exactly as in the standard path (same in/out dims, same scatter2scatter_lora). Threads expert_biases through _parallel_linear_maybe_lora. 2. sm_120 fallback: when the sonic-moe kernel can't run (Blackwell) and the experts use a standard layout, sonicmoe_experts_forward_with_lora transparently routes to the scattermoe path, which runs there. Validated vs an eager reference (fp32 with TF32 off, ~1e-6): output, dX, and every gradient (gpt_oss base: d_gate_up/d_down + both biases; LoRA: dA/dB for gate_up and down) for base + LoRA, fp32 + bf16. gpt_oss MoE+LoRA fwd+bwd, vendored Triton vs eager, RTX PRO 6000 (Blackwell): gpt-oss-20b N=2048 9.5x / 0.10x mem gpt-oss-20b N=8192 3.6x / 0.32x mem gpt-oss-120b N=4096 48.8x / 0.05x mem MXFP4 gpt_oss weights dequantize on the fly via parallel_linear_lora (bf16 compute), as with other MXFP4 models on this path; fused MXFP4 for gpt_oss is not yet wired. * perf(scattermoe): use fused MXFP4 kernel in experts forward, no dequant scattermoe_experts_forward dequantized base MXFP4 weights to bf16 every step (the old `_get_base_param(...).transpose(2,1)` actually crashed on an MXTensor, so MXFP4 only ever ran via the dequant-based HFScatterMoEGatedMLP path). The fused MX kernel (scatter2scatter_lora_mx, dequant inside the K-loop) and all the plumbing (selective_mx_weights_fwd / get_active_experts / remap_expert_indices / selective_lora_weights) existed but were only exercised in tests. Wire them in: when the base param is MXFP4 and LoRA is active on both projections, keep the weights packed (4-bit) and route through the fused MX kernel. Gated by is_mxfp4_param, which is False for bf16/fp16 params and when torchao is absent, so non-MXFP4 models fall through to the unchanged bf16 path. The MX kernel is pure-Triton software dequant (LUT), so it needs no hardware MXFP4 support. MXFP4-without-LoRA dequantizes explicitly (the fused kernel is LoRA-only; MXTensor has no transpose). Memory (E=32, H=2048, I=768, N=2048, rank=16, RTX PRO 6000): persistent expert weights: MXFP4 80MB vs bf16 302MB (3.8x) fwd+bwd transient: fused-MX 489MB vs full-dequant 3020MB (6.2x) Validated vs the dequantized-weight reference within MX rounding tol (~1e-3..1e-2) on output, dX, and the active-expert slice of LoRA dA/dB. * feat(ep): sonicmoe+LoRA+EP on sm_120 via scattermoe, fused MXFP4 in EP path Factor the weight/LoRA prep (incl. the fused-MXFP4 active-expert selection) into _prepare_weights_and_lora and use it in both scattermoe_experts_forward and the EP sentinel-skip forward, so base MXFP4 stays packed (no dequant) under EP too. Wire _sonicmoe_local: on a device where the sonic-moe CUTLASS kernel can't run (sm_120) and the experts use a standard layout, route to scattermoe_experts_forward_ep -- giving sonicmoe + LoRA + EP on Blackwell (sentinel-skip + fused MXFP4). Elsewhere sonicmoe+EP still raises (needs the upstream EP-sentinel kernel). Validated MXFP4+EP vs the bf16-dequant reference within MX tol on output, dX, and the active-expert slice of LoRA dA/dB; _sonicmoe_local routing covered. bf16 EP path and the EP plugin suite unchanged (28 passed). * style: pre-commit lint (ruff format/check) for the EP+MXFP4 changes ruff-format reflow + fixes: drop redundant torch importorskip (F811), rename ambiguous I->IM (E741), lambda->def in tests (E731), zip(..., strict=True) (B905). * feat(scattermoe): fused NVFP4 base + LoRA, no dequant Mirror the MXFP4 fused path for NVFP4 so base NVFP4 weights stay 4-bit packed instead of dequantizing to bf16. NVFP4 shares the FP4 E2M1 packing with MXFP4 but scales per 16-element block with an E4M3 (fp8) value times an optional per-tensor scale, so the dequant is codebook(nibble) * e4m3_block_scale * per_tensor -- not a power of two. - is_nvfp4_param + selective_nvfp4_weights_fwd: slice the NVFP4Tensor to active experts and fold the E4M3 block scale (* per-tensor) into a linear fp32 scale, returned as an MXWeights with block_size=16, scale_is_linear=True. The packed buffer stays 4-bit; only the small [a, N, K/16] scale tensor is materialized. - Kernel: the fwd + dX MXFP4 inner loops gain a SCALE_LINEAR branch -- load the scale as a linear fp multiplier instead of E8M0 exp2(byte-127) -- threaded through both scatter2scatter_lora_mx / _dX_mx wrappers, which now read block_size + scale_is_linear off the container. MXFP4 (SCALE_LINEAR=False) is byte-identical to before. - Reuses the MXWeights container, so parallel_linear_lora's isinstance(_, MXWeights) check routes NVFP4 through the fused kernel with no change; _prepare_weights_and_lora adds NVFP4 alongside MXFP4 for both the standard and EP forwards. Validated vs the dequantized-weight reference within NV rounding tol (dX/dA/dB ~1e-3.. 1e-2) through the standard and EP forwards; MXFP4 suite still green (14 passed). --- .../expert_parallel/experts_fn.py | 61 +++- src/axolotl/integrations/kernels/README.md | 8 +- .../kernels/libs/scattermoe_lora/experts.py | 311 +++++++++++++++++- .../libs/scattermoe_lora/kernels/lora_ops.py | 32 +- .../libs/scattermoe_lora/mx_weights.py | 68 +++- .../libs/scattermoe_lora/selective_dequant.py | 7 + .../kernels/libs/sonicmoe/experts.py | 29 +- .../scattermoe_lora/test_ep_sentinel_skip.py | 127 +++++++ .../scattermoe_lora/test_gptoss_layout.py | 185 +++++++++++ .../test_mxfp4_experts_forward.py | 216 ++++++++++++ .../test_nvfp4_experts_forward.py | 138 ++++++++ 11 files changed, 1134 insertions(+), 48 deletions(-) create mode 100644 tests/integrations/kernels/scattermoe_lora/test_ep_sentinel_skip.py create mode 100644 tests/integrations/kernels/scattermoe_lora/test_gptoss_layout.py create mode 100644 tests/integrations/kernels/scattermoe_lora/test_mxfp4_experts_forward.py create mode 100644 tests/integrations/kernels/scattermoe_lora/test_nvfp4_experts_forward.py diff --git a/src/axolotl/integrations/expert_parallel/experts_fn.py b/src/axolotl/integrations/expert_parallel/experts_fn.py index 89473fd112..88ad49d0b9 100644 --- a/src/axolotl/integrations/expert_parallel/experts_fn.py +++ b/src/axolotl/integrations/expert_parallel/experts_fn.py @@ -51,23 +51,58 @@ def _maybe_install_decorator_attrs(experts): experts.is_transposed = False +def _mask_sentinels(recv_topk_idx, recv_topk_weights): + """Map ``-1`` remote sentinels to expert 0 / weight 0 for kernels that index by + expert id and don't filter (grouped_mm).

On sm_120, `use_sonicmoe` with a standard-layout model transparently falls back to the ScatterMoE Triton path, which runs there. `gpt_oss` on sm_120 should use `use_scattermoe` directly (bf16 base; MXFP4 weights dequantize on the fly as with other MXFP4 models — fused MXFP4 for `gpt_oss` is not yet wired). ## Feature comparison diff --git a/src/axolotl/integrations/kernels/libs/scattermoe_lora/experts.py b/src/axolotl/integrations/kernels/libs/scattermoe_lora/experts.py index 9199c8a595..b5601848c5 100644 --- a/src/axolotl/integrations/kernels/libs/scattermoe_lora/experts.py +++ b/src/axolotl/integrations/kernels/libs/scattermoe_lora/experts.py @@ -6,8 +6,16 @@ import torch +from .mx_weights import selective_mx_weights_fwd, selective_nvfp4_weights_fwd from .parallel_experts import flatten_sort_count, parallel_linear from .parallel_linear_lora import get_lora_params_from_wrapper, parallel_linear_lora +from .selective_dequant import ( + get_active_experts, + is_mxfp4_param, + is_nvfp4_param, + remap_expert_indices, + selective_lora_weights, +) def _has_peft_wrapper(module): @@ -91,6 +99,7 @@ def _parallel_linear_maybe_lora( grouped_in, grouped_out, gates=None, + expert_biases=None, ): """Call parallel_linear or parallel_linear_lora depending on whether LoRA is active.""" if lora_tuple is not None: @@ -105,6 +114,7 @@ def _parallel_linear_maybe_lora( lora_A, lora_B, scaling, + expert_biases=expert_biases, grouped_in=grouped_in, grouped_out=grouped_out, gates=gates, @@ -116,51 +126,223 @@ def _parallel_linear_maybe_lora( sorted_expert_idxs, sorted_scattered_idxs, expert_offsets, + expert_biases=expert_biases, grouped_in=grouped_in, grouped_out=grouped_out, gates=gates, ) -def scattermoe_experts_forward( - self, - hidden_states: torch.Tensor, - top_k_index: torch.Tensor, - top_k_weights: torch.Tensor, -) -> torch.Tensor: - """ScatterMoE experts forward with fused-LoRA support.""" - # Assumes the standard expert layout: gate_up concatenated as [E, 2I, H], - # gated SwiGLU, no expert bias. gpt_oss-style experts (interleaved gate/up, - # transposed [E, H, 2I], expert bias) would be silently miscomputed by the - # fixed transpose/chunk below, so reject rather than corrupt training. - if ( +def _prepare_weights_and_lora( + gu_param, + dn_param, + sorted_expert_idxs, + expert_offsets, + num_experts, + gup_lora, + down_lora, + dtype, +): + """Resolve the gate_up / down weights (+ routing + LoRA) for the grouped GEMM. + + For an MXFP4 or NVFP4 base with LoRA on both projections, keep the weights packed + (4-bit) and route through the fused kernel: select the active experts and remap the + routing / LoRA to that compact set (dequant happens inside the kernel K-loop; NVFP4 + reuses the MXWeights container with linear E4M3 block scales).

Previously, torch.compile on any QLoRA model crashed with ctypes.ArgumentError the first time a Linear4bit forward fell into the fast path. Also: - Drop dead legacy-list quant_state branch (not produced by bnb 0.40+). - Drop the unused `out=` parameter (no production callers; grep-confirmed). - Drop the HAS_CUDA_STREAM version gate (axolotl pins bnb >> 0.43.3). - Rewrite tests/e2e/kernels/test_quantize.py to use real bnb.functional.quantize_4bit fixtures instead of synthetic ones whose blocksize=32 was silently invalid (the old ctypes path skipped validation). Adds compile regression tests for both nested (double-quant) and non-nested paths. Validated: - Eager bench vs main at 1024², 4096², 4096x11008 within ±2% noise. - Unit tests pass on torch 2.11.0 + bnb 0.49.1. - End-to-end: Qwen3.5-0.8B QLoRA train (lora_mlp/qkv/o_kernel=true, exercises dequantize in autograd Function fwd+bwd) + merge-lora pipeline succeed. * review: add docstrings to internal helpers + tighten transposed test Addresses CodeRabbit nits on PR #25: - Docstrings on _nf4_dequantize_op and its register_fake impl to lift docstring coverage above the 80% threshold. - test_dequantize_transposed now asserts value equality vs bnb.functional.dequantize_4bit(...).t() in addition to shape, so a layout/content regression would actually fail the test. Skipped CodeRabbit's fullgraph=True nit: tracing under fullgraph=True currently fails on both main and branch (same _SimpleCData.__new__ trace error before reaching the is_compiling() branch). Investigating is out of scope for this PR; default-mode torch.compile is what the fix targets and is verified working. Skipped CodeRabbit's CUDA_STREAM caching concern: the cache pattern is byte-identical to main and removing it costs +5-21% at the kernel level. Stream-management refactor is a separate concern. * docs: trim docstrings/comments to one-line WHY only - Module + dequantize() docstrings condensed to single line. - CUDA_STREAM comment dropped benchmark numbers and version reference. - Removed task-history language ("no longer crashes", "vs the prior implementation", "Regression:") from docstrings; comments now describe permanent invariants, not the PR diff. * style: ruff format dequantize() call arg lists per pre-commit * review: key CUDA_STREAM cache by device Per CodeRabbit: the single-global stream cache could in principle return the wrong device's stream for a multi-device-single-process caller. In practice axolotl always runs one process per CUDA device, so this is defensive rather than fixing a known reproducer. Using `setdefault` keeps the cache race benign under threading (worst case: redundant current_stream() call) and drops the `global` keyword since the dict is mutated in place, never rebound. * fix broken MX tests from transformers 5.8.1 upgrade --------- Co-authored-by: Wing Lian --- src/axolotl/kernels/quantize.py | 270 +++++++++++++---------------- tests/e2e/kernels/test_quantize.py | 138 ++++++--------- 2 files changed, 179 insertions(+), 229 deletions(-) diff --git a/src/axolotl/kernels/quantize.py b/src/axolotl/kernels/quantize.py index ff564fecc6..eb5c08a4c1 100644 --- a/src/axolotl/kernels/quantize.py +++ b/src/axolotl/kernels/quantize.py @@ -1,18 +1,102 @@ """Dequantization utilities for `bitsandbytes` and FP8 integration.""" import ctypes +from typing import List import bitsandbytes as bnb import torch from bitsandbytes.functional import QuantState, get_ptr -from packaging.version import Version cdequantize_blockwise_fp32 = bnb.functional.lib.cdequantize_blockwise_fp32 cdequantize_blockwise_fp16_nf4 = bnb.functional.lib.cdequantize_blockwise_fp16_nf4 cdequantize_blockwise_bf16_nf4 = bnb.functional.lib.cdequantize_blockwise_bf16_nf4 -CUDA_STREAM: torch.cuda.Stream | None = None -HAS_CUDA_STREAM: bool = Version(bnb.__version__) > Version("0.43.3") +# Cached per-device: per-call current_stream() measurably slows this hot path. +CUDA_STREAM: dict[torch.device, torch.cuda.Stream] = {} + + +def _ctypes_nf4_dequant( + W: torch.Tensor, + absmax: torch.Tensor, + code2: torch.Tensor, + absmax2: torch.Tensor, + offset: torch.Tensor, + blocksize: int, + blocksize2: int, + shape, + dtype: torch.dtype, +) -> torch.Tensor: + """Direct-ctypes NF4 double-dequant body (Unsloth-derived fast path).""" + target_device = W.device + out = torch.empty(tuple(shape), dtype=dtype, device=target_device) + n_elements_absmax = absmax.numel() + out_absmax = torch.empty( + n_elements_absmax, dtype=torch.float32, device=target_device + ) + + stream = CUDA_STREAM.get(target_device) + if stream is None: + stream = CUDA_STREAM.setdefault( + target_device, torch.cuda.current_stream(target_device) + ) + + cdequantize_blockwise_fp32( + get_ptr(code2), + get_ptr(absmax), + get_ptr(absmax2), + get_ptr(out_absmax), + ctypes.c_int(blocksize2), + ctypes.c_int(n_elements_absmax), + stream, + ) + out_absmax += offset + + fx = ( + cdequantize_blockwise_fp16_nf4 + if dtype == torch.float16 + else cdequantize_blockwise_bf16_nf4 + ) + fx( + get_ptr(None), + get_ptr(W), + get_ptr(out_absmax), + get_ptr(out), + ctypes.c_int(blocksize), + ctypes.c_int(out.numel()), + stream, + ) + + # bnb convention: leading-dim-1 packed weight signals a transposed view. + if W.shape[0] == 1: + return out.t() + return out + + +@torch.library.custom_op("axolotl::nf4_dequantize", mutates_args=()) +def _nf4_dequantize_op( + W: torch.Tensor, + absmax: torch.Tensor, + code2: torch.Tensor, + absmax2: torch.Tensor, + offset: torch.Tensor, + blocksize: int, + blocksize2: int, + shape: List[int], + dtype: torch.dtype, +) -> torch.Tensor: + """Opaque-to-Dynamo wrapper around the direct-ctypes NF4 dequant body.""" + return _ctypes_nf4_dequant( + W, absmax, code2, absmax2, offset, blocksize, blocksize2, shape, dtype + ) + + +@_nf4_dequantize_op.register_fake +def _(W, absmax, code2, absmax2, offset, blocksize, blocksize2, shape, dtype): + """FakeTensor shape/dtype inference for the registered op (trace-time only).""" + out = torch.empty(tuple(shape), dtype=dtype, device=W.device) + if W.shape[0] == 1: + return out.t() + return out def dequantize_fp8( @@ -20,17 +104,7 @@ def dequantize_fp8( scale_inv: torch.Tensor, dtype: torch.dtype = torch.bfloat16, ) -> torch.Tensor: - """Dequantize FP8 block-quantized weights: W_dequant = W_fp8 * scale_inv. - - Args: - W: FP8 weight tensor [out_features, in_features] in float8_e4m3fn. - scale_inv: Per-block inverse scale [ceil(out/block), ceil(in/block)] - or per-tensor scalar. - dtype: Output dtype (default bf16). - - Returns: - Dequantized tensor in the specified dtype. - """ + """Dequantize FP8 block-quantized weights: W_dequant = W_fp8 * scale_inv."""

Add an override set so qwen3_5 / qwen3_5_moe / gemma4_text keep routing to the axolotl branches, while genuinely new model types (qwen3_5 multimodal text variants, qwen3_next, ministral, nemotron) correctly adopt native 0.8.0 dispatch. Also refresh the ORPO trl-compat shim comment (still required: liger 0.8.0 still imports ORPOTrainer from the old trl.trainer path). * style(liger): collapse multi-line inline comments to one line Addresses CodeRabbit: src/**/*.py inline comments must be one short line. The full rationale lives in the PR description / prior commit message. * feat(liger): adopt native gemma4_text dispatch for FLCE support liger-kernel 0.8.0's apply_liger_kernel_to_gemma4_text supports fused linear cross entropy (and uses the more-correct casting_mode="gemma" fp32 RMSNorm with with_scale=False v_norm handling), which axolotl's custom gemma4 branch skipped. Drop gemma4_text from the native-dispatch override set so it routes to liger's native path and gains FLCE. Multimodal gemma4 (no native entry) keeps the axolotl branch; its FLCE warning now points to the gemma4_text path. Validated on GPU (torch 2.11.0, transformers 5.5.4): tiny Gemma4ForCausalLM training-mode forward with native FLCE -> finite loss, out.logits is None (fused path, no logit materialization), finite grads. * docs(liger): clarify multimodal gemma4 FLCE warning (0.8.0 gap, not absolute) Multimodal gemma4 FLCE is supported upstream (liger PR #1203, merged post-0.8.0) but not in the pinned 0.8.0 release, so the warning now scopes the limitation to 0.8.0 rather than implying it is fundamentally unsupported. * style(liger): collapse gemma4 RMSNorm docstring to one line --- pyproject.toml | 2 +- src/axolotl/integrations/liger/plugin.py | 21 ++++++++++++++------- 2 files changed, 15 insertions(+), 8 deletions(-) diff --git a/pyproject.toml b/pyproject.toml index 01cac4b8b0..03aaf2e7b6 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -81,7 +81,7 @@ dependencies = [ "bitsandbytes==0.49.1 ; sys_platform != 'darwin'", "triton>=3.4.0 ; sys_platform != 'darwin'", "xformers>=0.0.33.post2 ; sys_platform != 'darwin' and platform_machine != 'aarch64'", - "liger-kernel==0.7.0 ; sys_platform != 'darwin'", + "liger-kernel==0.8.0 ; sys_platform != 'darwin'", "torchao==0.17.0 ; sys_platform != 'darwin' and platform_machine != 'aarch64'", # Architecture-specific diff --git a/src/axolotl/integrations/liger/plugin.py b/src/axolotl/integrations/liger/plugin.py index eedf221ede..c7f8c560e9 100644 --- a/src/axolotl/integrations/liger/plugin.py +++ b/src/axolotl/integrations/liger/plugin.py @@ -20,7 +20,7 @@ def get_input_args(self): return "axolotl.integrations.liger.LigerArgs" def pre_model_load(self, cfg): - # shim: liger-kernel 0.7.0 imports ORPOTrainer from old trl path + # shim: liger imports ORPOTrainer from old trl.trainer (now trl.experimental.orpo) import trl.trainer from trl.experimental.orpo import ORPOTrainer @@ -81,7 +81,13 @@ def patched_init(self, *args, **kwargs): LigerFusedLinearCrossEntropyLoss.__init__ = patched_init - if cfg.model_config_type in MODEL_TYPE_TO_APPLY_LIGER_FN: + # liger 0.8.0 natively dispatches these, but axolotl's branches add kernels native lacks + axolotl_override_liger_fn = {"qwen3_5", "qwen3_5_moe"} + + if ( + cfg.model_config_type in MODEL_TYPE_TO_APPLY_LIGER_FN + and cfg.model_config_type not in axolotl_override_liger_fn + ): apply_liger_fn = MODEL_TYPE_TO_APPLY_LIGER_FN[cfg.model_config_type] liger_fn_sig = inspect.signature(apply_liger_fn) kwargs = {} @@ -235,9 +241,8 @@ def patched_init(self, *args, **kwargs): rms_norm=cfg.liger_rms_norm, swiglu=cfg.liger_glu_activation, ) - elif cfg.model_config_type in ("gemma4", "gemma4_text"): - # Gemma4: offset=0 (NOT 1 like Gemma3), in_place=False required for - # gradient checkpointing compatibility, RoPE incompatible (separate q/k). + elif cfg.model_config_type == "gemma4": + # multimodal gemma4 only; gemma4_text uses liger 0.8.0 native dispatch (incl.

Byte-identical to the reference scanner, gated on torch.get_num_threads() == 1 (the DataLoader-worker default) since the per-op dispatch overhead regresses it under multi-threaded torch. 1.3-1.5x speedup on real Gemma 3 / Gemma 4 / Qwen 2 tokenizers, tie on Llama 3 (more boundaries, more tensor ops). - Fused process_labels: composes role/pad/media masks into one boolean keep tensor and does a single labels[~keep] = -100 write instead of the previous 3-4 sequential masked writes. Structural cleanup; the measured speedup is ~0ms since the prior masked-write cost was already dwarfed by the scanner. - One-shot warning when MultiModalChatDataCollator is built with dataloader_num_workers in (None, 0): MM training does heavier collator-side work than text and synchronous collation blocks the GPU. Tests: - tests/test_vectorized_scanner.py: 2,000-config differential fuzz + targeted edge cases (Pixtral [/INST] rewind, longest-prefix tie, train_on_eos modes, empty end_tokens, include_end leak gate). - tests/test_process_labels_fusion.py: 50 random batches per strategy across all 9 process_labels-overriding strategies (450 fuzz cases) asserting torch.equal between pre-refactor and fused implementation. - tests/test_mm_collator_warnings.py: num_workers=0 warning regression. * fix: address coderabbit feedback and lint * test(mm-mask): add Voxtral/Mistral3/InternVL/Glm4v strategy coverage - test_process_labels_fusion.py: factories + parity-fuzz entries for the four strategies (200 new fused-vs-legacy assertions); no-boundaries branch in _build_alternating_turns now injects pad/extras so the pad/media masking path is exercised. - test_processing_strategies.py: behavioral tests (process_labels, train_on_inputs, role_boundaries_override, batch handling, InternVL error paths) plus dispatch routing for VoxtralProcessor, Mistral3Processor, and InternVLProcessor. 572 -> 788 passing across the PR's four test files. * perf(mm-mask): bisect end-finder + slice-fill in vectorized scanner The vectorized scanner's per-row loop still did O(span) Python work: a linear walk over end-match flags to find each turn's end, and element-wise bytearray writes to fill spans. Replace both: - Precompute each boundary's end-match start positions (sorted via nonzero) and bisect for the next end >= start_of_content. - Fill keep-spans with bytearray slice assignment and materialize each row tensor once via torch.frombuffer. Byte-identical to the reference scanner; ~2x faster than the prior vectorized path (≈3x vs reference) on 8x3-6k batches, widening with turn length. Adds long-span / multi-end-marker parity fuzz that the original filler<=200 generator under-exercised. --------- Co-authored-by: Wing Lian --- src/axolotl/core/builders/causal.py | 18 + src/axolotl/processing_strategies.py | 333 ++++++++++++-- tests/test_mm_collator_warnings.py | 82 ++++ tests/test_process_labels_fusion.py | 640 ++++++++++++++++++++++++++ tests/test_processing_strategies.py | 252 +++++++++++ tests/test_vectorized_scanner.py | 650 +++++++++++++++++++++++++++ 6 files changed, 1926 insertions(+), 49 deletions(-) create mode 100644 tests/test_mm_collator_warnings.py create mode 100644 tests/test_process_labels_fusion.py create mode 100644 tests/test_vectorized_scanner.py diff --git a/src/axolotl/core/builders/causal.py b/src/axolotl/core/builders/causal.py index a82c0dd05d..93d751f8ba 100644 --- a/src/axolotl/core/builders/causal.py +++ b/src/axolotl/core/builders/causal.py @@ -49,6 +49,23 @@ LOG = get_logger(__name__) +_MM_NUM_WORKERS_WARNED: set = set() + + +def _warn_if_num_workers_zero_for_mm(cfg, log) -> None: + if not getattr(cfg, "processor_type", None): + return + if getattr(cfg, "dataloader_num_workers", None) not in (None, 0): + return + if getattr(cfg, "train_on_inputs", False): + return + if "mm_num_workers_zero" in _MM_NUM_WORKERS_WARNED: + return + _MM_NUM_WORKERS_WARNED.add("mm_num_workers_zero") + log.warning( + "Increase dataloader_num_workers to speed up multimodal training with assistant-only loss masking (currently dataloader_num_workers=0)." + ) + class HFCausalTrainerBuilder(TrainerBuilderBase): """ @@ -560,6 +577,7 @@ def _ds_get(cfg_obj, key): train_on_eos, "set" if role_boundaries_override else "none", ) + _warn_if_num_workers_zero_for_mm(self.cfg, LOG) kwargs["processing_strategy"] = get_processing_strategy( self.processor, diff --git a/src/axolotl/processing_strategies.py b/src/axolotl/processing_strategies.py index 497e5b5108..677e21d7f3 100644 --- a/src/axolotl/processing_strategies.py +++ b/src/axolotl/processing_strategies.py @@ -1,9 +1,11 @@ """Module containing ProcessingStrategy classes and its derivative for different MultiModal Model types""" +import bisect from copy import deepcopy from dataclasses import dataclass, field from typing import Optional +import torch from PIL import Image, ImageOps from PIL.Image import Resampling from torch import Tensor, zeros_like @@ -333,10 +335,10 @@ def convert_messages_to_multimedia_messages(messages: list[dict]) -> list[dict]: return processed_examples - def _mask_non_assistant(self, labels: Tensor) -> Tensor: - """Mask non-trainable role regions to -100 using ``self.role_boundaries``.""" + def _mask_non_assistant_keep(self, input_ids: Tensor) -> Tensor: + """Return a [B, L] bool keep tensor (True = contributes to loss).""" if self.train_on_inputs: - return labels + return torch.ones_like(input_ids, dtype=torch.bool) # Legacy no-op for boundary-less strategies;

Key trick: combined = expert*T + tenant is also sorted by expert, so a single sort yields both the expert grouping (base) and the combined grouping (LoRA). ScatterMoEMultiLoRA reuses the existing scatter2scatter base + LoRA-projection ops with combined offsets/ids; T==1 reduces to the single-adapter behaviour exactly. - multi_lora.py: build_multilora_routing() (one sort -> both groupings), ScatterMoEMultiLoRA autograd Function (frozen W; grads to per-(expert,tenant) A/B and X), scatter2scatter_multilora() entry point. - Backward is sync-free and grouped: dX_lora = scaling*(dY@B)@A as two scatter2scatter GEMMs keyed by the combined id (no Python per-expert expert_offsets[e].item() sync loop) -- up to 57x vs the loop on a 128-expert config (28.0 -> 0.49 ms at T=8), CUDA-graph / torch.compile friendly. - dA/dB via a dedicated grouped-Gram kernel (_grouped_gram_kernel) fed the forward's saved XA and the backward's YB: token-dim reduction only, writing each tile straight into the [E*T*R,K] / [N,E*T*R] grad layout (empty (expert,tenant) groups self-zero). 17-27x vs the shared split kernel at E=8/T=32, exact bf16 parity (dA/dB err 0.0). The shared single-adapter kernel in lora_ops.py is left byte-for-byte unchanged. - test: forward + backward (dX/dA/dB) vs a dense reference across shapes incl. T=1, many-group (forces empty groups), and rank-64 (BLOCK_R>16); a misroute-detection guard confirms routing is actually checked. Follow-up: wire into the ScatterMoE layer forward (build combined ids from the router's expert ids + the tenant routing); a single fully-fused inner kernel (separate LoRA index inside _compute_expert_block_lora) is a further perf step. * feat(sonicmoe): multi-adapter (expert x tenant) LoRA via combined materialization SonicMoE dispatches opaque CUTLASS/CuteDSL grouped GEMMs that can't fuse LoRA, so the single-adapter path materializes W_eff[e] = W[e] + scaling*(B_e@A_e) and hands it to the kernel. Extend that to multi-tenant co-training over the combined (expert, tenant) grouping: materialize all E*T effective weights W_eff[e*T+t] = W[e] + scaling_t*(B_{e,t}@A_{e,t}) and remap each token-slot's expert id to e*T + t, so the same opaque GEMM (num_experts = E*T) routes every tenant in one launch. The kernel is unchanged; T==1 reduces to the single-adapter MoELoRAMaterialize exactly. - multi_lora.py: MoEMultiLoRAMaterialize (autograd; frozen base, grads to per- (e,t) A/B), materialize_multi_lora_experts(), combined_expert_ids() id remap. Materialized directly in combined order (einsum over the [E,T,...] view yields a contiguous [E*T,...] -- no reorder copy), with in-place scale/base-add and scaling folded onto the rank-sized grads, so the op's footprint is exactly 1x W_eff (one buffer). - test: forward+backward vs a per-tenant standalone reference through an exact PyTorch grouped-GEMM stand-in (the real CUTLASS kernel needs the sonicmoe pkg, absent on sm_120); T==1 == single-adapter; id-remap unit check. Memory is the design tradeoff: W_eff is T x the expert stack (intrinsic to the opaque kernel -- the shared frozen base must be broadcast into each tenant's group). A per-tenant loop (T launches, 1x W_eff) is the memory-bound alternative if T is large; left as a follow-up alongside wiring this into the experts forward. * fix(scattermoe-lora): honor live ALLOW_TF32 in grouped-Gram dA/dB backward grouped_gram.py and multi_lora.py did `from .lora_ops import ALLOW_TF32`, binding the bool *value* at import time. Toggling `lora_ops.ALLOW_TF32` (e.g. to force true fp32) therefore never reached the grouped-Gram dA/dB kernels, which kept running TF32 while the forward GEMMs honored the flag -- LoRA weight grads carried ~8e-4 relative error (textbook TF32, 2^-10) vs ~4e-7 for the fp32 forward. Surfaced by the fp32 gpt_oss LoRA test (tol 3e-4) on main; the multi-adapter path has the same latent bug in its own grouped-Gram kernel. Reference the live `lora_ops.ALLOW_TF32` module global at call time instead. With the default (True) production numerics are byte-identical, and bf16/fp16 training is unaffected (allow_tf32 only applies to fp32-input tl.dot). The flag is now consistent across the whole backward: disabling TF32 (or training in fp32) yields true-fp32 dA/dB, error 8e-4 -> ~1e-7, matching the forward. Adds a multi-adapter regression test that disables TF32 and asserts tight fp32 parity (dA/dB ~1e-7) -- would fail at ~1e-3 with the stale import-time copy. --- .../kernels/libs/scattermoe_lora/__init__.py | 5 + .../scattermoe_lora/kernels/grouped_gram.py | 7 +- .../libs/scattermoe_lora/multi_lora.py | 455 ++++++++++++++++++ .../kernels/libs/sonicmoe/__init__.py | 8 + .../kernels/libs/sonicmoe/multi_lora.py | 94 ++++ .../test_scattermoe_multi_lora.py | 144 ++++++ .../integrations/test_sonicmoe_multi_lora.py | 104 ++++ 7 files changed, 814 insertions(+), 3 deletions(-) create mode 100644 src/axolotl/integrations/kernels/libs/scattermoe_lora/multi_lora.py create mode 100644 src/axolotl/integrations/kernels/libs/sonicmoe/multi_lora.py create mode 100644 tests/integrations/test_scattermoe_multi_lora.py create mode 100644 tests/integrations/test_sonicmoe_multi_lora.py diff --git a/src/axolotl/integrations/kernels/libs/scattermoe_lora/__init__.py b/src/axolotl/integrations/kernels/libs/scattermoe_lora/__init__.py index f5148634e6..25f7855f7d 100644 --- a/src/axolotl/integrations/kernels/libs/scattermoe_lora/__init__.py +++ b/src/axolotl/integrations/kernels/libs/scattermoe_lora/__init__.py @@ -16,3 +16,8 @@ "parallel_linear_lora", "lora_ops", ] +from .multi_lora import ( # noqa: E402,F401 + ScatterMoEMultiLoRA, + build_multilora_routing, + scatter2scatter_multilora, +) diff --git a/src/axolotl/integrations/kernels/libs/scattermoe_lora/kernels/grouped_gram.py b/src/axolotl/integrations/kernels/libs/scattermoe_lora/kernels/grouped_gram.py index c0b7f0f712..9d5601d644 100644 --- a/src/axolotl/integrations/kernels/libs/scattermoe_lora/kernels/grouped_gram.py +++ b/src/axolotl/integrations/kernels/libs/scattermoe_lora/kernels/grouped_gram.py @@ -18,7 +18,8 @@ import triton import triton.language as tl -from .lora_ops import ALLOW_TF32, _block_r_for_rank, _bucket_m +from . import lora_ops +from .lora_ops import _block_r_for_rank, _bucket_m def _grouped_gram_configs(): @@ -183,7 +184,7 @@ def grouped_lora_weight_grads( scaling=scaling, RANK_IS_I=True, BLOCK_R=block_r, - allow_tf32=ALLOW_TF32, + allow_tf32=lora_ops.ALLOW_TF32, ) grid_b = lambda meta: (e_total, triton.cdiv(n_dim, meta["BLOCK_WIDE"])) # noqa: E731 @@ -205,6 +206,6 @@ def grouped_lora_weight_grads( scaling=scaling, RANK_IS_I=False, BLOCK_R=block_r, - allow_tf32=ALLOW_TF32, + allow_tf32=lora_ops.ALLOW_TF32, ) return dA, dB diff --git a/src/axolotl/integrations/kernels/libs/scattermoe_lora/multi_lora.py b/src/axolotl/integrations/kernels/libs/scattermoe_lora/multi_lora.py new file mode 100644 index 0000000000..4f5480a60e --- /dev/null +++ b/src/axolotl/integrations/kernels/libs/scattermoe_lora/multi_lora.py @@ -0,0 +1,455 @@ +# SPDX-License-Identifier: Apache-2.0 +# Copyright (c) Axolotl AI +# Licensed under the Apache License, Version 2.0 + +"""ScatterMoE + multi-adapter LoRA. + +Extends the single-adapter ScatterMoE+LoRA path to co-train many LoRA adapters +("tenants") over one frozen expert stack.

Happy finetuning! 🚀 + +### TIPS + +- For single GPU, remove FSDP block. It would require >=180GB GPU. +- On cloud, if using volume mount, pointing the HF cache (via `HF_HOME`) at a local disk keeps weight load fast. +- Train the experts only. Do not add attention or module LoRA on a `use_dsv4_kernels` run: it is unsupported and breaks the experts-only FSDP2 invariant (data-independent backward collectives across ranks). +- Keep `attn_implementation: eager` so the dsv4 kernels plugin owns the attention path. +- `sample_packing` attends within the sliding window across packed documents, exactly as plain eager attention would.
