<｜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 compute the average internal degree of the detected communities?
### Response:
import networkx as nx
from cdlib import algorithms
from cdlib import evaluation

# Create a graph from the Astrophysics collaborations file
G = nx.read_gml('astro-ph.gml')

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

# Compute the average internal degree of the detected communities
avg_internal_degree = evaluation.average_internal_degree(G, communities)

# Print the computed average internal degree
print(avg_internal_degree)
