Can't pip install torch

Question

I was trying to pip install stanza and got this message:

ERROR: No matching distribution found for torch>=1.3.0 (from stanza)

I then ran pip install torch and got the following (the website won't let me include too much code, so here's the full error)

  ERROR: Command errored out with exit status 1:

DEPRECATION: Could not build wheels for torch which do not use PEP 517. pip will fall back to legacy 'setup.py install' for these. pip 21.0 will remove support for this functionality. A possible replacement is to fix the wheel build issue reported above. You can find discussion regarding this at https://github.com/pypa/pip/issues/8368.

I can see that you have a Windows machine, so from this official pytorch website, you can build the command that the best for your requirements and system, try this

pip install torch===1.6.0 torchvision===0.7.0 -f https://download.pytorch.org/whl/torch_stable.html

And here, all of the torch packages are located, both Windows, MacOS, and Linux

It got installed, and so did stanza. But now when I try to load the 'en' model in stanza, I get an error saying `module 'torch' has no attribute 'tensor'` – chocojunkie Aug 18 '20 at 13:46
@chocojunkie This is different problem. Please update your question or create another question. – vmemmap Aug 18 '20 at 13:48

I came across the same error and realized that Python 3.9 is not supported by Pytorch yet. I created another virtual environment with Python 3.7 and the installation worked.

this turned out to be true still in Nov 2021. in my case once i changed the interpreter to python 3.8, everything was okay – jcp Nov 05 '21 at 22:35
