PyTorch not downloading
It looks like it can't find a version called "1.2.0+cpu" from it's list of versions that it can find (0.1.2, 0.1.2.post1, 0.1.2.post2). Try looking for one of those versions on the PyTorch website.
I go to the PyTorch website and select the following options
PyTorch Build: Stable (1.2)
Your OS: Windows
Package: pip
Language: Python 3.7
CUDA: None
(All of these are correct)
Than it displays a command to run
pip3 install torch==1.2.0+cpu torchvision==0.4.0+cpu -f https://download.pytorch.org/whl/torch_stable.html
I have already tried to mix around the the different options but none of them has worked.

ERROR: ERROR: Could not find a version that satisfies the requirement torch==1.2.0+cpu (from versions: 0.1.2, 0.1.2.post1, 0.1.2.post2)
ERROR: No matching distribution found for torch==1.2.0+cpu
I tried to do pip install pytorch but pytorch doesn't support pypi
