<｜begin▁of▁sentence｜>### Instruction:
Given the Les Miserables social network graph which you can read from a GML file named lesmis.gml, can you use the Louvain method in CDlib to perform community detection? And can you compute the internal density of the community set?
### Response:
import networkx as nx
from cdlib import algorithms, evaluation

# Create a graph from Les Miserables dataset
G = nx.read_gml('lesmis.gml')

# Apply the Louvain community detection algorithm to the graph
communities = algorithms.louvain(G)

# Compute the internal edge density of the detected communities
internal_edge_density_score = evaluation.internal_edge_density(G, communities)

print(internal_edge_density_score)
