Setup script fails on Arch Linux: ModuleNotFoundError: No module named 'pkg_resources'

[ron-1986]

This is what I get when trying to run the setup script on a current Arch linux:

> ~/opt/kohya_ss/kohya_ss -> ./setup.sh 
Skipping git operations.
Arch Linux or Arch base detected.
Python TK found...
Switching to virtual Python environment.
Traceback (most recent call last):

    import pkg_resources
ModuleNotFoundError: No module named 'pkg_resources'
Exiting Python virtual environment.
Setup finished! Run ./gui.sh to start.
Please note if you'd like to expose your public server you need to run ./gui.sh --share

Any advice on what to do? Thank you!

Are you using python version higher than 3.10.9 but lower than 3.11.0 in the venv?

[ron-1986]

Hey,

I am not sure. How would I configure what python version is being used in the venv?

Default Python version on the system is 3.13.1 But I also installed 3.10.16-1 from here: https://aur.archlinux.org/packages?O=0&SeB=nd&K=python+3.10&outdated=&SB=p&SO=d&PP=50&submit=Go

I have this in /usr/bin:

Maybe setup.sh is not using 3.10 for the venv? How would I configure that? Sadly I have no idea how python works behind the curtains.

pkg_resources is part of python's setuptools package. Are you able to install through pip, specifically for python3.10 and not your system's python3.13?

[ron-1986]

Sorry I have no idea about the inner workings of python. I am lost here. Could you provide instructions on how to install the required packages? I have python-pip and python-env installed. Some tutorial suggested it. But I can't make it work.

[b-fission]

I'm going to suggest using miniconda since it avoids having to compile from source packages.

Refer to the install instructions for Miniconda here but basically, this...

mkdir -p ~/miniconda3
wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh -O ~/miniconda3/miniconda.sh
bash ~/miniconda3/miniconda.sh -b -u -p ~/miniconda3
rm ~/miniconda3/miniconda.sh

Side note: The above commands will make a directory called miniconda3 in your home dir, which is where conda's python packages will reside. If you don't know what you're doing, do not remove/relocate miniconda3 since that may break the install.

Now set up conda environment with python 3.10

source ~/miniconda3/bin/activate
conda create -n py310 python=3.10.16
conda activate py310

And do the setup for kohya_ss as usual. I recommend deleting the existing venv if you have one present.

cd kohya_ss
rm -fr venv
./setup.sh

If that all works out, start the GUI.

./gui.sh

I believe there will be additional things to set up, but see if you can get the web GUI to run.

[ron-1986]

Thank you very much! I will try that out and report back.

[ron-1986]

This worked! I was able to reach the GUI. Did not have time to train yet. Thank you very much for your help. I guess this will help a lot of people on Arch!

[frutiemax92]

I'd like to get it working without miniconda and I'm getting the same error. Any hint on how to do it?

EDIT - Solved it by deleting the virtual environment folders.

@wonder75 Did it work to train?

I have no problem running the gui without miniconda, I use pyenv instead.

Did it work with the the UV version or only legacy?

Do you use nvidia? If so, what cuda package did you use?
