Unable to run optimus-manager: Python ModuleNotFoundError

[CodePurble]

Describe the bug I freshly installed Arch linux, and optimus-manager does not run, it exits with the below error:

Traceback (most recent call last):
  File "/usr/bin/optimus-manager", line 5, in <module>
    from optimus_manager.client import main
ModuleNotFoundError: No module named 'optimus_manager'

I believe there is something wrong with the install as Python is not able to find the required files. I have installed the optimus-manager package from the AUR, with no manual intervention. Is there an issue with my Python installation by any chance?

optimus-manager was working perfectly fine in all my earlier installations on the same device.

System info Please include :

• Distro: Arch Linux
• WM: i3
• DM: SDDM
• The version of optimus-manager you are using : optimus-manager
• Your custom optimus-manager configuration file at /etc/optimus-manager/optimus-manager.conf, if you made one

Had the same issue. Switching to optimus-manager-git and rebooting fixed it for me.

Optimus manager is not the only software. There are other softwares written in python that had those issues, specially when updating versions. I had that very same issue on optimus-manager when updating from 3.11 to 3.12.

You should be fine after reinstalling optimus-manager.

Yep, switching to optimus-manager-git fixes the issue. Thanks for the help everyone!
