A1111 requires python 3.10. We have no plan to change that.

rafstahelin commented 8 months ago

Ok but auto1111, focus, comfyui, and kohya all work fine as it is with 3.12Can I downgrade to 3.10 and just rebuild all the venv’s?Best, Raf On 8 Feb 2024, at 16:13, Chenlei Hu @.***> wrote: A1111 requires python 3.10. We have no plan to change that.

If you have an existing venv, you can reference it by setting it here: https://github.com/lllyasviel/stable-diffusion-webui-forge/blob/291ec743b603fdcd9c58e60dc5ed3d866c53bc4c/webui-user.bat#L5

Hello. will you kindly provide a step-by-step instruction on how to fix the problem for us? I know nothing about python and venv and really want to use forge. Thank you very much.

So I was able to get Forge to work on Python 3.11, in Ubuntu 24.04. Here are the steps I followed:

Add the PPA for extra Python libraries to the Ubuntu package manager. For more detailed instructions see here: The commands are basically this:
```
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt update
```
Install a Stable Diffusion compatible python version AND the python venv module package.
```
sudo apt install python3.11 python3.11-venv
```
(For this next step, I recreated the whole 'venv' folder, just to be sure of avoiding conflicts. This may not be strictly necessary.)

In the folder where you installed / extracted / downloaded your Stable Diffusion Forge), rename any existing 'venv' folder to something else. I suggest 'venv.old'.
Create a new 'venv' folder with this command:
```
python3.11 -m venv "venv"
```
In the folder where you installed / extracted / downloaded your Stable Diffusion Forge), edit the file 'webui-user.sh'.

Change the section:

# python3 executable
#python_cmd="python3"

to be:

    # python3 executable
    python_cmd="python3.11"

Optional: Make any other custom changes you want to the 'webui-user.sh' file, such has the COMMANDLINE_ARGS parameters.
Now start the webui for Stable Diffusion as normal. If you followed the steps to create a fresh 'venv' folder, this will trigger a full reinstall and download any necessary packages, and compile them.

That should fix your Stable Diffusion for Ubuntu 24.04!

Note: I was able to do this with Python 3.10 on Automatic1111 also. Same solution with adjusted version numbers for that.

There is another way I found, which helped me on Ubuntu 24.04, with pyenv:

sudo apt install -y make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev xz-utils tk-dev libffi-dev liblzma-dev python3-openssl git
curl https://pyenv.run | bash

Add the following lines to your .bashrc (nano ~/.bashrc):

export PATH="$HOME/.pyenv/bin:$PATH"
eval "$(pyenv init --path)"
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"

exec "$SHELL"
pyenv install 3.10.6 (which stable diffusion webui forge needs)
cd /to/your/stable/diffusion/folder
pyenv local 3.10.6

Then you can test it with: python3 --version and it should show you 3.10.6, so inside of that directory it will use this version, while your global python 3.12.1 (or whatever version) which Ubuntu system uses will not change. just ./webui.sh
