louvain

✓ import louvain

Basic community detection using the Louvain algorithm on a random graph.

import igraph as ig import louvain G = ig.Graph.Erdos_Renyi(n=100, p=0.1, directed=False) partition = louvain.find_partition(G, louvain.ModularityVertexPartition) print(partition.membership)

Debug

Known issues

deprecatedThe standalone 'louvain' package is deprecated; consider using 'leidenalg' for newer algorithms

fix

Use pip install leidenalg and import leidenalg (also by same author, more efficient)

affects: >=0.8.0

gotchaMust install python-igraph separately

fix

Run: pip install python-igraph

affects: all

gotchaThe 'louvain' module does not install igraph automatically; missing igraph causes ImportError

fix

Ensure igraph is installed and imported before louvain

affects: all
