Describe the bug

After starting the mmaction2 Docker container, I tried to run the demo according to the documentation.

However, the demo failed to run because MMCV2.2.0 was installed. I specified MMCV2.1.0 and it worked fine.

Sorry, I mistakenly thought that mmaction2 supported MMCV2.2.0

[22222222z]

I meet the same question. How did you solve it?

I meet the same question. How did you solve it?

I changed this line in the docker/Dockerfile as follows.

RUN mim install mmengine mmcv==2.1.0

Current MMaction seems to require less than MMCV 2.2.0: https://github.com/open-mmlab/mmaction2/blob/4d6c93474730cad2f25e51109adcf96824efc7a3/mmaction/__init__.py#L8-L19
