mmcv CUDA compatibility

[palvors]

You should add

python -m pip install mmcv==2.2.0 -f https://download.openmmlab.com/mmcv/dist/cu118/torch2.1/index.html

instead of mmcv and mmengine in your requirement because, that mentioned before we must use cuda 11.8 and by default mmcv install with cuda 12.6

Thanks for the clarification. I've added a note about using the specific MMCV installation.
