<｜begin▁of▁sentence｜>### Instruction:
Given the graph of Astrophysics collaborations which you can read from a gml file named astro-ph.gml, can you use the Louvain community detection algorithm in cdlib to find the communities and then compute the Erdos-Renyi modularity for the resulting partition?
### Response:
import networkx as nx
from cdlib import algorithms, evaluation

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

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

# Computing the Erdos-Renyi modularity
mod = evaluation.erdos_renyi_modularity(G, communities)

print(f'Erdos-Renyi Modularity: {mod.score}')
