how would someone install pytorch using pip on python 3.9?
when i tried the command the website used pip install torch==1.7.0+cpu torchvision==0.8.1+cpu torchaudio===0.7.0 -f https://download.pytorch.org/whl/torch_stable.html
and it returned the error code
ERROR: Could not find a version that satisfies the requirement torch==1.7.0+cpu (from versions: 0.1.2, 
0.1.2.post1, 0.1.2.post2)
ERROR: No matching distribution found for torch==1.7.0+cpu

even when i change the code to satisfy the requirement it comes up with more errors like
ModuleNotFoundError: No module named 'tools.setup_helpers'

Searching for &quot;1.7.0&quot; at the https://download.pytorch.org/whl/torch_stable.html page, you can see that only wheels for Python 3.6, 3.7, and 3.8 are available.
So there is no official wheel for Python 3.9.
Update:
PyTorch currently doesn't work with Python 3.9, there are known issues being resolved: https://github.com/pytorch/pytorch/issues/47776
