<｜begin▁of▁sentence｜>### Instruction:
As a knowledgeable assistant in network analysis, you would like to utilize the Paris hierarchical graph clustering algorithm to detect the different research communities in the Astrophysics collaborations graph. The graph is accessible through the astro-ph.gml file, which contains information about the collaborations in the field of astrophysics.
### Response:
import networkx as nx
from cdlib import algorithms

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

# Perform hierarchical graph clustering using the Paris algorithm
coms = algorithms.paris(G)

# Print the communities
for community in coms.communities:
    print(community)
