Hello, thanks for your great work!

When I run the evaluation example using the provided command, it raises the following error:

Do you have solutions for that problem? Thanks!

Hi @Christinepan881, it seems that the mmcv is not installed successfully. You might need to uninstall mmcv/mmdetection/xxx first, then follow the installation instruction step by step and make sure everything is installed successfully without errors.

Thanks for your reply. That is what I did, but the issue still occurs. Do you consider to update this repo with a higher version of mmcv, torch, cuda?

Although I have followed the instructions, the same happens for me too. FYI: The reason for the problem seems to be the compatibility between torch and mmcv modules. Installing pytorch 1.9.1+cu111 (where I used different version due to CUDA before.) and reinstalling all mmcv modules solved the problem for me.
