Unpickling stack underflow

When I try to run models/download_models.py, I get the following error:
'''

@West102 What version of PyTorch are you using?

[westcode990]

@ProGamerGov I am using PyTorch version 1.7.0 and Python 3.8.5

@West102 I can't seem to reproduce the issue with PyTorch 1.7.0, though I was using Python 3.6. I also didn't see anything in the change notes that would cause this issue. There's various reports of similar issues on the PyTorch Github page, but no mention of the cause. Have you tried reinstalling PyTorch? Can you reliably reproduce the error?

I also have copies of the models (with the correct changes) available for download here: https://drive.google.com/drive/folders/1OGKfoIehp2MiJL2Iq_8VMTy76L6waGC8
