No checkpoints saved，训练过程中是否会保存pth？

[Hellmett]

May I ask, I tried to train a model, but during the training process, only log and .py files were saved in the corresponding folder under work_dir, and there is no pth file. What could be the reason for this?
请问我尝试训练了一下，但是训练过程中在work_dir下对应文件夹里只有log和.py文件没有pth保存，是什么原因呢？

checkpoint_config = dict(by_epoch=False, interval=16000)
