[Bug]: Cannot find torch version 2.0.1 when running webui-user.bat on Windows 10

[PochiiBoy]

Checklist

• The issue exists after disabling all extensions
• The issue exists on a clean installation of webui
• The issue is caused by an extension, but I believe it is caused by a bug in the webui
• The issue exists in the current version of the webui
• The issue has not been reported before recently
• The issue has been reported before but has not been fixed yet

What happened?

When I run webui-user.bat on Windows 10 it will start to install torch and torchvision but is unable to find the version 2.0.1 of torch.
Other issues related to this from what I have seen were on another OS and was a memory issue but my allocated Vmemory (12800mb) is much above my recommended (3958mb).

Steps to reproduce the problem

1. Go to installation of stable-diffusion-webui
2. Run webui-user.bat

What should have happened?

Torch should have been installed and the rest of the install should have continued.

What browsers do you use to access the UI ?

It seems not to be a bug but I ran into the same issue. Torch is not compatible with newer Python versions. Even though I set the path in the webui to 10.06 with "set PYTHON=" the version in the venv directory was the latest version I had installed there by i was unable to install torch

Fix:

1. Uninstall all Python versions except version 10.06
2. delete the venv directory
3. run webui-script

Sweet! Thank you. I'll try this out real soon but I bet this will fix it.

I decided to uninstall everything and install Python 3.10.6 and then install everything else again. I have python 3.10.6 and no other version and its installed to my PATH but I get the same error about torch :c

[alexanderMal]

Does the pyvenv file in the venv directory contain the correct python version?

Can you post your error message again? The old message stated Python 3.12.1 in the top left.

[PochiiBoy]

Yes, in the pyvenv file it shows 3.10.6.

This looks like an other error did you pull the latest version from the git? Maybe you can take a look at this:
#5928

[PochiiBoy]

When I git clone it am I getting the latest version? Cause that is what I always do.

clone is usually a one time process. I´m not sure what appens if you git clone multiple times. Maybe it updates maybe it skips. Try going to your stable diffusion directory where you can see the .git folder (if you have enabled display hidden elements) and run the command git pull this will update to the latest version. Then delete the venv folder and execute the webui-user file.

[PochiiBoy]

It was all up to date but deleting the venv folder worked ^^ I just had to add the --no-half and --skip-torch-cuda-test commandline args :)))

2. delete the venv directory
3. run webui-script

so you basically did this and it worked (including step 2)

[PochiiBoy]

Yee, for some reason the first time i deleted it with the new python version it didnt work

[loo-kevin]

Based on my installation experience, I would like to give two suggestions:

1. Install python-3.10.6. 32-bit cannot match any version of the torch package, but 64-bit will do.
2. This error message may not reflect the actual error reason: pip is not installed. In fact, I installed pip and there may still be unknown errors. Finally, I reinstalled python and ran it again.

Thanks @loo-kevin , I had the same issue on Arch Linux and pip was missing.
So I solved after a simple $ yay -S python-pip
