Need help with updating xformers. (0.0.17 -> 0.0.20)

[vielix3]

Hello! I recently updated my Automatic1111 via git pull to version 1.4.0 released earlier this week. The program runs fine, but when it launches I get this semi-warning in the cmd window:

=====================================================

You are running xformers 0.0.17.

The program is tested to work with xformers 0.0.20.

To reinstall the desired version, run with commandline flag --reinstall-xformers.

=====================================================

Can someone walk me through how to update my xformers from 0.0.17 to 0.0.20?

I tried updating my webui-user.bat file to have --reinstall-xformers instead of --xformers and it just says "--reinstall-xformers is not a module" or something and loads a1111 without xformers, so I know that's not the correct way to do it. Just started using A1111 and SD a week ago, so I'm still in a bit over my head. Any help here is appreciated. Please and thank you.

Here are a couple of ways to do this. If you use one option, you do not have to do the other.

Option 1: Using webui-user.bat

Edit the webui-user.bat to include --xformers --reinstall-xformers for the command line arguments as well as the desired package version. Then run the webui-user.bat as normal.

Example:

@echo off

set PYTHON=
set GIT=
set VENV_DIR=
set XFORMERS_PACKAGE=xformers==0.0.20
set COMMANDLINE_ARGS=--xformers --reinstall-xformers

call webui.bat

Remember to remove --reinstall-xformers after you have installed the xformers package, or else it will try to reinstall xformers every time you run the webui-user.bat.

Option 2: Using the command line

Open a command line, go to the directory where you have stable-diffusion-webui installed, and then run the commands below:

cd venv/Scripts
activate
pip install --force-reinstall xformers==0.0.20

Brief explanation: This will take you to the virtual environment and force install xformers to the version specified even if another version of xformers is installed.

More info about virtual environments: https://docs.python.org/3.10/library/venv.html

Thank you so much! Option 1 worked for me. Although quick question: when I removed "--reinstall-xformers" from the .bat file after the update, I also removed the "set XFORMERS_PACKAGE=xformers==0.0.20" from the .bat file as well. I assume this is ok? My xformers is listed as 0.0.20 in the webui and everything seems to work fine.

Glad to hear it helped. Yes, you can also remove the set XFORMERS_PACKAGE=xformers==0.0.20 line. It was only needed to determine which version of the xformers package to install.

Same problem - same solution - option 1 was easy and successful. Thank you!

The easiest way is to delete the venv folder.

Does Sadtalker support 0.0.22?
