Used the install guide on pytorch.org on how to install it and the command I'm using is

pip install torch===1.4.0 torchvision===0.5.0 -f https://download.pytorch.org/whl/torch_stable.html

But it's coming up with this error;

ERROR: Could not find a version that satisfies the requirement torch===1.4.0 (from versions: 0.1.2, 0.1.2.post1, 0.1.2.post2)

ERROR: No matching distribution found for torch===1.4.0

Is this even a me-related issue? Can other people use this command?

Pip is installed and works for other modules, Python 3.8, CUDA version 10.1, Windows 10 Home 2004

Looks like this issue is related to virtual environment. Did you try recommended installation line in another/new one virtual environment? If it doesn't help the possible solution might be installing package using direct link to PyTorch and TorchVision builds for your system:

pip install https://download.pytorch.org/whl/cu101/torch-1.4.0-cp38-cp38-win_amd64.whl

pip install https://download.pytorch.org/whl/cu101/torchvision-0.5.0-cp38-cp38-win_amd64.whl
