Thank you! The main(OUTPUT_DIR) function is intended to be used later. I’ll keep it and add at least a pass statement to avoid syntax issues. Implementation is coming soon.

这两段 for 循环的作用是提取训练集和测试集中的第一个batch 数据，并将其移动到对应的计算设备（如 GPU 或 CPU）。其中的 break 语句用于确保循环只执行一次，防止遍历完整个数据集。主要用途是用于调试或验证数据加载过程是否正确。如果后续进入正式训练阶段，这两个 break 语句是可以删除的，从而让训练/测试完整遍历整个数据集。

文件路径请使用os.path.join来拼接

感谢提醒！我会将相关路径拼接方式统一改为 os.path.join(OUTPUT_DIR, ...) 的形式。

这是测试过程中实时监测的Loss文件，我们会在后续提交中将它们移除。

请转换成.pdparams格式的文件

- 这个文件和checkpoint.pth有什么区别，如果是重复的文件，可以删除，否则请转换成
.pdparams格式的文件
There was a problem hiding this comment.
感谢您的提醒！这两个文件的主要区别如下：
1）checkpoint.pth：保存的是训练过程中的中间权重，同时还包含了优化器状态、当前轮次、loss 等信息，方便训练中断后继续训练（resume training）。
2）trained_model.pth：保存了最终的模型参数，用于推理或测试阶段的加载。
