Can't install torch (windows)

Question

I am trying to install torch using pypy. when I run pypy -m pip install torch , I get this error:

ERROR: Could not find a version that satisfies the requirement torch (from versions: none)
ERROR: No matching distribution found for torch

Why is this happening, and how can I successfully install torch?

I want to install torch (above 1.6.0), I can't

Answer 1

try:

pip3 install torch

pip install pytorch

Answer 2

Do you have python version 3.11?. If yes, try using a lower version. It doesn't work with Python 3.11. When I had anaconda installed with Python 3.9, it worked fine, but when I updated python version to 3.11, I was unable to install it and was getting the same error.

Answer 3

Pytorch is not compatible with PyPy. Support can be tracked on this pytorch issue . If it would install and run, what benefit would you expect? Have you profiled a pytorch project to see how much time is spent in pure-python code? The PyPy JIT cannot look inside C/C++/CUDA code, and the cpyext interface code to interact with the Python C-API is about 4x slower than CPython, so until HPY is more heavily used I would not expect any performance gain when using PyPy.
