Hello,
The fairly popular (in the world of bioinformatics) ScanPy package uses
a Python version of the louvain clustering algorithm implemented by:
https://github.com/vtraag/louvain-igraph
https://pypi.org/project/louvain/
which installs into the "louvain" dist-packages directory.
(from debc)
./usr/lib/python3/dist-packages/louvain/
I have it mostly packaged
However currently in the Debian archive there's a different louvain
package
https://github.com/taynaud/python-louvain
https://pypi.org/project/python-louvain/
https://salsa.debian.org/python-team/packages/python-louvain
It installs into (according to debc)
./usr/lib/python3/dist-packages/community/
Unfortunately for this package we now automatically run autodep8 which
fails because the import name is community and not louvain.
