Hi,
This issue is mainly from mmdetection which is also used in detectron2...
So it would help if you create an issue there is the following does not work.. :)

The following just pretty much reinstalls the packages but in regards to your CUDA versions, this issue mainly center's around the version mismatches, so try the following if not try and check up on if the versions you have support each other...

pip uninstall mmcv-full mmdet
CUDA_HOME=/usr/local/cuda-10.1 pip install mmcv-full==1.7.1 -f https://download.openmmlab.com/mmcv/dist/cu101/torch1.7.0/index.html
pip install mmdet==2.10.0

Hope this helps
Thank you
