Please help walkthrough installation (python not found, torch issues)

[alledian1326]

I'm not very Github/command prompt literate and I've been trying to follow the main directions to install this.

On my local computer C:\Users\user\ I installed the stable-diffusion-webui folder. I'm trying to

python launch.py

but I get this printout:

INCOMPATIBLE PYTHON VERSION

This program is tested with 3.10.6 Python, but you have 3.12.3.
If you encounter an error with "RuntimeError: Couldn't install torch." message,
or any other error regarding unsuccessful package (library) installation,
please downgrade (or upgrade) to the latest version of 3.10 Python
and delete current Python and "venv" folder in WebUI's directory.

You can download 3.10 Python from here: https://www.python.org/downloads/release/python-3106/

Alternatively, use a binary release of WebUI: https://github.com/AUTOMATIC1111/stable-diffusion-webui/releases

Use --skip-python-version-check to suppress this warning.

raise RuntimeError(
RuntimeError: Torch is not able to use GPU; add --skip-torch-cuda-test to COMMANDLINE_ARGS variable to disable this check

So it looks like there are two errors: 1) Needs python 3.10 and 2) Torch error?

I did a search in the issues/community pages and see other people had similar issues. One solution recommends I reinstall python 3.10, which I did (I now have 3.12 and 3.10 both installed), and to modify the webui-user.bat file to include:

set PYTHON=python3.10.exe

And tried the python launch.py again, but I get the same error. Please walk me through this, this is a fairly simple error but due to my lack of familiarity with installing things this way I am extremely confused.

Are familiar with "environment variables"? Specifically, the PATH variable? If your answer to either of these is the slightest bit "no", then Google's Gemini will be a far more patient teacher. No offense, just trying to be honest and also helpful.

On the other hand, if you are familiar with both of those, then you should already know the answer to your first issue. And trust me when I say "first."

[Git-Maniac]

Open the Command Prompt (cmd.exe). Type “python” and press Enter.

You should see it prints out Python 3.10.
