cannot import name 'iri_sub' from 'iri12py'

[Adim-a11y]

I am on an Ubuntu 20.04 system and use Python 3.8. I tried to install pyglow in a virtual environment. I managed to install it, but I encountered this error: ImportError: cannot import name 'iri_sub' from 'iri12py' (/home/adim/Desktop/space_venv/lib/python3.8/site-packages/iri12py.cpython-38-x86_64-linux-gnu.so).
Could you assist or suggest a solution to resolve this issue?
Thanks in advance.

This likely means IRI did not compile correctly. Are there any clues in the output?

The error appears when I import pyglow, before using it.

This probably means that IRI did not compile properly when you installed pyglow. Do you have the output from the installation process? It's a long mess but maybe there is a clue in there.
