PyTorch import broken, unable to pip install
So all of a sudden my code broke. Error: Unable to import torch, No module named torch. So I attempt to install torch; error, ModuleNotFoundError: No module named 'tools.nnwrap'. I delete my venv and re-create it, same thing. I try it outside the venv, same issue. I look up the issue, apparently I should go here. I do, try several of the install commands, with cuda, without, all broken. What do I do? Am on Arch Linux if that's relevant, maybe I broke something.

It's a recent issue with Python 3.9, as expected: it's sadly not compatible with PyTorch as of right now (04/12/2020), and the error message isn't explicit about it. The issue is currently still open and pending, and all you can do is revert to 3.8 for the time being.
