[Bug]: Unable to install webui due to torch

[SanderBouwhuis]

Is there an existing issue for this?

• [X] I have searched the existing issues and checked the recent builds/commits

What happened?

I installed everything according to the 'Steps to reproduce the problem' section. I then ran webui-user.bat. I get this error message:

If you encounter an error with "RuntimeError: Couldn't install torch." message,
or any other error regarding unsuccessful package (library) installation,

Steps to reproduce the problem

1. I downloaded and copied the repository files to C:\Utilities\Stable-Diffusion
2. I downloaded and copied GFPGANv1.4.pth in C:\Utilities\Stable-Diffusion
3. I downloaded and copied 'sd-v1-4-full-ema.ckpt' in C:\Utilities\Stable-Diffusion\models\Stable-diffusion
4. I downloaded and copied a couple of ESRGAN files in C:\Utilities\Stable-Diffusion\models\ESRGAN

What should have happened?

I expected the program to install correctly

@SanderBouwhuis torch isn't officially supported on python 3.11 yet, you could try changing line ~222 in launch.py: https://github.com/AUTOMATIC1111/stable-diffusion-webui/blob/0cc0ee1bcb4c24a8c9715f66cede06601bfc00c8/launch.py#L221-L223

to:

    torch_command = os.environ.get('TORCH_COMMAND', "pip install --pre torch -f https://download.pytorch.org/whl/nightly/cpu/torch_nightly.html")

to install the nightly (unstable) version instead.

If you installed from the microsoft store, you get 3.11, make sure you install Python 3.10.6, and tick the add to path checkbox

@bolshoytoster @ClashSAN Thanks a huge bunch for helping me! Ok, I got farther with the change @bolshoytoster proposed, but still no complete success:

@SanderBouwhuis the error is:

Try reading this stackoverflow answer.

My graphics card supports the right version of CUDA. My graphics driver supports the right version of CUDA. I guess the Torch version still has bugs or incompatibilities.

I downgraded Python from v3.11 to v3.10.9 and it works now. I'm a little worried about using older versions which may contain vulnerabilities, so I hope that the Torch package will soon be updated.

Most old versions of software still recieve security updates (and v3.10.9 isn't really that old) so you should be fine.

mine work with v3.10.9
