I met a similar problem like you. After I changed the version of pytorch, I finally solved this question.

I used anaconda to install the pytorch. The version of python was 3.8. I firstly created a virtual environment using the following command: conda create -n zooming python=3.8

Then, in the virtual environment, I performed the command: conda install pytorch==1.4.0 torchvision==0.5.0 cudatoolkit=10.1 -c pytorch
