<｜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 community detection algorithm in cdlib to perform community detection? And can you compute the Newman-Girvan modularity of the detected communities?
### Response:
import networkx as nx
from cdlib import algorithms, evaluation

# Read the graph
G = nx.read_gml('astro-ph.gml')

# Perform community detection using the Louvain method
communities = algorithms.louvain(G)

# Compute the Newman-Girvan modularity
modularity = evaluation.newman_girvan_modularity(G, communities)

# Print the modularity
print(modularity.score)
