I’ll introduce how I resolved ERROR: Could not find a version that satisfies the requirement torch (from versions: none) and successfully installed PyTorch.

$ pip install torch
ERROR: Could not find a version that satisfies the requirement torch (from versions: none)

$ python -V
Python 3.12.1

I confirmed that I seemed to meet the installation requirements from INSTALL PYTORCH on the PyTorch official site.

NOTE: Latest PyTorch requires Python 3.8 or later. For more details, see Python section below.

Since it stated the above, I checked torch · PyPI and found that Python is only supported up to 3.10.

Programming Language * C++ * Python :: 3 * Python :: 3.8 * Python :: 3.9 * Python :: 3.10

I checked https://www.python.org/downloads/ and installed the latest 3.10.* version, 3.10.13.

asdf install python 3.10.13
asdf local python 3.10.13

$ pip install torch

That’s all from the Gemba, where I successfully installed PyTorch.
