Hello, it is mentioned in the readme file to use the PURE project for training mention detection model.
Command: python run_entity.py
--do_train --do_eval --eval_test
--learning_rate=5e-6 --task_learning_rate=5e-6
--train_batch_size=32
--eval_batch_size=108
--context_window 0
--max_span_length 15
--task grailqa
--data_dir grailqa_data/json/
--model bert-base-uncased
--output_dir grailqa_models/checkpoint
--num_epoch 10
--seed 42

But the PURE project has no task "grailqa" as given in arguments.
Can you also mention the code changes required in PURE to make it run for grailqa.
