Reproduces the problem - code sample

when you debug the script tools\infer.py in pycharm, the error happens, but it's fine to run the script in command line. the virtual python environments is the same.

Seems mmcv has not been installed correctly, you may try reinstalling it and run your command again:

pip uninstall mmcv
pip uninstall mmcv-full
pip install openmim
mim install mmcv

Seems mmcv has not been installed correctly, you may try reinstalling it and run your command again:

pip uninstall mmcv
pip uninstall mmcv-full
pip install openmim
mim install mmcv

I try it,but still show ModuleNotFoundError: No module named 'mmcv'
