Unable to install PyTorch in PyCharm (Python 3.9 / macOS)

Question

Environment:

pip version: 20.2.4
interpreter: Python 3.9.0
OS: macOS Big Sur
Everything else is also up to date

I tried the following commands in the Terminal and none worked:

pip install torch
pip3 install torch
pip install torch torchvision torchaudio

I get different error messages for each command, but this is the output of "pip install torch":

Collecting torch
  Using cached torch-0.1.2.post2.tar.gz (128 kB)
Requirement already satisfied: pyyaml in /Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages (from torch) (5.3.1)
Using legacy 'setup.py install' for torch, since package 'wheel' is not installed.
Installing collected packages: torch
    Running setup.py install for torch: started
    Running setup.py install for torch: finished with status 'error'

DEPRECATION: The -b/--build/--build-dir/--build-directory option is deprecated. pip 20.3 will remove support for this functionality. A possible replacement is use the TMPDIR/TEMP/TMP environment variable, possibly combined with --no-clean. You can find discussion regarding this at https://github.com/pypa/pip/issues/8333.

Answer 1

Okay, I got this fixed by using the conda package manager instead of pip’s. Conda uses python version 3.8.5, whereas version 3.9 was used for my pip manager. I’m not quite sure if the issue of incompatibility was due to pip itself, or the fact that it is using python version 3.9. Anyways after downloading the graphical macOS installer:

conda install pytorch torchvision torchaudio -c pytorch

And that should successfully install PyTorch!
