Fedora 39: Stable Diffusion Automatic1111 : INCOMPATIBLE PYTHON VERSION error

Question

Good day.

I'm having a bit of a problem running stable diffusion on Fedora 39

My system info:

It used to run fine on Fedora 38, but now it complains about the wrong Python version and I have no idea how to make it work.

The error message:

INCOMPATIBLE PYTHON VERSION
 
This program is tested with 3.10.6 Python, but you have 3.12.0.
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/
 
 
 
Use --skip-python-version-check to suppress this warning.

Error code: 1

I tried to do the following:

1. I installed pyton3.10
2. I edited the file webui-user.sh and changed

#python3 executable
#python_cmd="python"

to

#python3 executable
#python_cmd="python3.10"

After that I deleted venv folder and tried to run webui.sh again,but it didn't help.

What did I miss?

Thank you

Answer 1

If the error remains the same perhaps despite the fact you installed Python 3.10, the script executed with 3.12 (perhaps). Try to uninstall ALL python versions and install 3.10 again. After that, remove venv and create it again.

Answer 2

I believe you need to simply uncomment the python_cmd flag, e.g.

#python3 executable
python_cmd="python3.10"

Notice the lack of "#" on the second line.
