[Bug]: Could not find a version that satisfies the requirement xformers==0.0.17

[seadra]

Is there an existing issue for this?

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

What happened?

On Arch Linux, trying to run with xformers enabled results in failure.

launch.py script is hard-coded to install version 0.0.17 of xformers, however, according to pip, the only available versions on Linux (amd64 arch) are 0.0.1, 0.0.2, 0.0.3, 0.0.4, 0.0.5, 0.0.6, 0.0.7, 0.0.8, 0.0.9, 0.0.10, 0.0.11, 0.0.12, 0.0.13, 0.0.16rc424, 0.0.16rc425, 0.0.16 so the installation fails.

Steps to reproduce the problem

1. Go to stable-diffusion-webui directory
2. Run ./webui.sh --xformers

What should have happened?

Should have installed xformers and started normally

改成0.0.16,或者换回官方的镜像源

[seadra]

No idea what that means, but running pip manually to install xformers==0.0.17, I get the same result

[theclashoftitans]

Same issue on Manjaro with a fresh install

[theclashoftitans]

Tried installing the Linux .whl from https://pypi.org/project/xformers/#files

$ pip install xformers-0.0.19-cp310-cp310-manylinux2014_x86_64.whl 
ERROR: xformers-0.0.19-cp310-cp310-manylinux2014_x86_64.whl is not a supported wheel on this platform.

Not sure what "cp310-cp310-manylinux2014_x86_64" is, but apparently pip thinks it's not supported on current Arch-based x86_64 distros.

[theclashoftitans]

If "cp310" means C Python 3.10, that might explain the issue? Arch-based distros are on Python 3.11. But again, no idea about the manylinux2014 part.

[seadra]

Python version seems to be the problem. I installed python310 package from AUR and setting

python_cmd="python3.10"

in webui-user.sh, removed venv directory, then ran ./webui.sh --xformers, and it worked OK!

I only have cuda from the system repository (12.1) installed, and #10125 didn't become a problem either.

Sorry for being a an absolute noob. Can you kindly indicate where you set python_cmd="python3.10" ? In which file do you add this line?

Thank you for sharing your solution.

Thank you for sharing your solution.

In webui-user.sh line 16. You must comment out the command and specify the version as mentioned above (3.10 instead of 3). Then you have to remove the hole venv directory in yourstable-diffusion-webui directory.

This solution worked for me, too.

[ablechow29]

@Ackrobrot Thank you for your explanation. Sadly this solution did not work for me.

I also installed python310 from AUR and set line 16 of webui-user.sh to webui-user.sh, like this:

# python3 executable
python_cmd="python3.10"

deleted venv directory, and ran ./webui.sh --xformers but the problem persisted. :^(

This is the output of my pacman -Qs python showing that python310 is indeed installed.

This is an xformers issue not sd-webui issue

[MarcoLeongDev]

it requires python3.10, for some reasons some version of ubuntu is unable to find that. A workaround:

sudo apt-get install software-properties-common -y
sudo add-apt-repository ppa:deadsnakes/ppa -y
sudo apt install python3.10 -y

Remember to remove venv directory for the environment to be rebuilt

[Wh1t3Fox]

Instead of downgrading your python environment just use pyenv. It works well

[seadra]

@ablechow29 you log says you're using python 3.11

Python 3.11.3 (main, Apr 5 2023, 15:52:25) [GCC 12.2.1 20230201]

You're not running ./webui.sh --xformers, you seem to be running stable-diffusion-webui/webui.sh --xformers from the parent directory

[RandomLegend]

btw. nothing mentioned here helped me so i went after it for my specific case.

I then just decided to install the developer preview of xformers which is 0.20

simply activate the venv of your stable diffusion and do pip install --pre -U xformers (or install it system-wide) Then it should work aswell.

[Wh1t3Fox]

@RandomLegend python version 3.10.11 is what I am running in pyenv with no issues at all.

@seadra , thanks for opening this issue, solving it, and sharing your answer. It worked for me!
