KD experiment problem and teacher checkpoint directory

[AmirEstiri]

Hi,
Great work! When I run the tools/train.py file with the config file I get this following error.
Also, where should I put the checkpoints after downloading them?
Thanks

Dear @AmirEstiri ，
You error seems to be a mmcv error, rather than an error of this repo. Please visit the mmcv documents (https://mmcv.readthedocs.io/en/latest/) for how to install it.

Besides, when you download the teacher checkpoint, you can put it anywhere and specify the path in model.train_cfg.teacher_checkpoint in your config.

Best
