Notes

To fix ModuleNotFoundError: No module named 'gi', install missing prereqs:

apt install python3-gi python3-cairo gir1.2-poppler

Be sure using SYSTEM Python, not Anaconda python or other user Python installs. Remove pympress and pympress*distinfo directories from ~/anaconda3/lib/python*/site-packages/pympress* or wherever it might be on $PATH.

Then install pympress with SYSTEM Python:

/usr/bin/pip3 install --user pympress
