How to upgrade xformers to latest version?

[suonnon]

I use this command to upgrade xformers to 0.0.19 (console log successful) but in A1111 UI is still showing ver 0.0.17.
pip install xformers
pip install --upgrade xformers

Does A1111 only support xformers ver 0.0.17 for now or am I missing something?

Modify this to 0.0.19，then use the --reinstall-xformers parameter.

stable-diffusion-webui/modules/launch_utils.py

Line 226 in 20ae71f

xformers_package = os.environ.get('XFORMERS_PACKAGE', 'xformers==0.0.17')

Can also be like this

Windows: add set XFORMERS_PACKAGE=xformers==0.0.19 to webui-user.bat.
Linux/Mac: add export XFORMERS_PACKAGE="xformers==0.0.19" to webui-user.sh.

There is no difference between installing and upgrading.

And I can do neither!

xformers released 0.0.20, compatible with PyTorch 2.0.1.

launch.py settings do not look the same anymore, it seems like it was moved somewhere else. updated guide please for 1.3.0?

[Sakura-Luna]

They have the same effect.

You are running xformers 0.0.16rc425.
The program is tested to work with xformers 0.0.20.
To reinstall the desired version, run with commandline flag --reinstall-xformers.

We vaguely get the arg to suffix without the actual prefixed command: What do we actually need to type? The workaround above is expired.

That helped me: https://www.youtube.com/watch?v=oacVlnTnQik
So in short in the installation folder right click and Git GUI Here -> run "pip install xformers==0.0.20" and then running the commandline --reinstall-xformers worked.

nope, wrong anwser....git gui does not have a "run" button.
