KeyError: "Recognizer3D: 'SwinTransformer3D is not in the models registry'"

Describe the bug

While running the training script “tools/train.py” this error occurs.

Reproduction Run the command:

python Video-Swin-Transformer/tools/train.py _Video-Swin-Transformer/configs/recognition/swin/swin_base_patch244_window877_kinetics600_22k.py

1. Did you make any modifications on the code or config? - No. Did you understand what you have modified? - No
2. What dataset did you use? - Kinetics600

Environment

1. Please run PYTHONPATH=${PWD}:$PYTHONPATH python mmaction/utils/collect_env.py to collect necessary environment information and paste it here.

[hust-nj]

Hi, please uninstall mmaction2, and run pip install -v -e . --user

[lyglxz]

maybe you can try

pip uninstall mmaction2
cd Video-Swin-Transformer
python setup.py develop

works for me while building a docker image
