AttributeError: module 'community' has no attribute 'best_partition'

Question

I try to run this code:

from cdlib import algorithms
import networkx as nx
G = nx.karate_club_graph()
coms = algorithms.louvain(G, resolution=1., randomize=False)

but the error remains the same. I have tried all options given by AttributeError: module 'networkx.algorithms.community' has no attribute 'best_partition'

but it doesn't work.

Also, I'm working in Google Colab and I have installed cdlib.

Answer 1

If still useful, this worked out for me :

pip uninstall community
pip install python-louvain

I could import community afterwards and use best_partition.

Answer 2

From this, it looks like there is a community python package that conflicts with the python-louvain package. Both packages happen to be pre-installed in google colab kernels. To avoid this conflict, I just uninstalled networkx, python-louvain and community and then reinstalled networkx and python-louvain. Finally I installed cdlib. After that I ran your code and everything worked well. So overall the code is:

!pip uninstall networkx
!pip uninstall python-louvain
!pip uninstall community
!pip install python-louvain
!pip install networkx

!pip install cdlib

from cdlib import algorithms
import networkx as nx
G = nx.karate_club_graph()
coms = algorithms.louvain(G, resolution=1., randomize=False)
print(coms)

And the ouput gives:
