ModuleNotFoundError: No module named 'endf'

[Worfran]

I followed the installation process in the quick installation guide, but OpenMC is not recognized as a Python package. When I try to import it using Python in the terminal within the repository on my PC, I get the following error:

$ python

import openmc ModuleNotFoundError: No module named 'endf'

I am new to this type of coding and to using Linux. I would greatly appreciate any help.

you have to add openmc to your PYTHONPATH for python to be able to find it

Thank you for your help! Since I’m using an Arch Linux distribution, I couldn’t use pip install to install packages system-wide. I tried using pipx, but that didn’t work either. Instead, I created a Python virtual environment and installed the package using pip install, as explained in this issue.
