AttributeError: module 'ssl' has no attribute 'PROTOCOL_TLSv1' #1029
Description
This problem is so outrageous that I can't find any information on the Internet. I write it down and hope others can solve it as soon as possible
Problem
Using Anaconda Python 3.8/3.9
$ conda install pytorch torchvision torchaudio cudatoolkit=11.1 -c pytorch -c nvidia
