<｜begin▁of▁sentence｜>### Instruction:
Given the Astrophysics collaborations Graph which you can read from a gml file named astro-ph.gml, can you use the Louvain method in cdlib to perform community detection? And can you compute the fraction of total edge volume that points outside the community?
### Response:
import networkx as nx
from cdlib import algorithms, evaluation

# Reading the astrophysics collaborations graph
G = nx.read_gml('astro-ph.gml')

# Applying the Louvain algorithm for community detection
communities = algorithms.louvain(G)

# Computing the conductance for the detected communities
conductance_score = evaluation.conductance(G, communities)

# Printing the conductance score
print(conductance_score.score)
