Hi, I use cuda 11, and I've created the conda env differently:
I removed from the conda_packagelist.txt the following: cuda, pytorch and torchvision
run:
conda create --name CornerNet_Lite --file conda_packagelist.txt --channel pytorch
conda activate CornerNet_Lite
pip install torch==1.7.1+cu110 torchvision==0.8.2+cu110 torchaudio===0.7.2 -f https://download.pytorch.org/whl/torch_stable.html

I recompiled the "_cpool" and it solved the issue for me.
