What should this feature add?

Why not let your installer respect the latest python version levels, vs having a user have to download older versions?

This a dependency compatibility issue. PyTorch, a main machine learning library, currently only supports 3.11.

[Regnalf]

I have this issue too on a mac. But in my case it crashes the update.

Installed Version is 3.12.
Would pyenv help?

[UnconnectedBedna]

Use pyenv to install and the version of python you need, refer to your specific operating system on how to.

Make sure pyenv is enabled system wise
On arch based it can be something like (from the directory where you run the application):

pyenv install 3.11.6
pyenv local 3.11.6
pyenv shell 3.11.6
python -m venv venv

[tcmbackwards]

On windows you can use python launcher (py.exe) to choose the version which builds the venv during the installation. The venv will use the right version of python from then on.

Edit install.bat:

@rem -------------- Install and Configure ---------------

old:
call python .\lib\main.py 

new:
call py -3.11 .\lib\main.py 

pause
exit /b

instead of virtualenv it would be better to revert to conda or miniconda to make it possible to have specific python install in env. i think so

What do you think conda does?
It's just another way of creating a containerized environment. :)

Use what YOU feel comfortable with, the important part is you make it "containerized" so you can control what python version is used.

pyenv local 3.11.6
pyenv shell 3.11.6
python -m venv venv

I followed the steps on manjaro - python 3.12 before, 3.11.6 after installation.
But I still get an error running the installer:

/home/leder/invokeai/.venv/bin/python: error while loading shared libraries: libpython3.11.so.1.0: cannot open shared object file: No such file or directory

No you did not follow the instructions quoted here, because if you did, the path would not be a hidden directory (.venv) but rather a directory called venv.

You also have to make sure the venv is activated and in your $PATH on each reboot (in .bashrc or whever shell you use) or you have to activate the pyenv every time.
Was that what you guys did? Rebooted without making sure you pyenv is available after?

Example:

export PYENV_ROOT="$HOME/.pyenv"
eval "$(pyenv init -)"

Edit
Also, the 3.11.6 was just a random example I used. Just use 3.11 instead and it will pull the latest available for you (3.11.9 IIRC)
You can remove a pyenv with pyenv uninstall x.x.x where x is the version numbers.

[JamesClarke7283]

It appears pytorch now supports 3.12, so you can remove the <3.11 requirement now.

Please drop Python 3.11 and add support of 3.12 or 3.13 already!
I know that security support of 3.11 will be till 2027, but Python 3.11 isn't receiving regular bug fixes anymore, and binary installers are no longer provided for it. Python 3.11.9 was the last full bugfix release of Python 3.11 with binary installers.
So on Windows platform it already outdated and there's no binaries to keep it secure. Since April 2 2024, 2 security patches were released.

[UnconnectedBedna]

Why though?
Just to make life as difficult as possible for the devs?
What advantages would be gained by changing?

As per install instructions, you are not required to install any kind of python on your system (manually).
And even if you make a manual install, you are still recommended to use uv
https://invoke-ai.github.io/InvokeAI/installation/manual/#manual-install

We'll use uv to install python and create a virtual environment, then install the invokeai package. uv is a modern, very fast alternative to pip.

You don't need any installation of python on windows.

And if you use pyenv, I am not 100% sure, but I feel pretty confident that as long as you keep it updated, it will keep you safe. (correct me if I am wrong here)
