<｜begin▁of▁sentence｜>### Instruction:
As a telecommunications engineer, you've been tasked with optimizing the collaboration network within a high-energy theory research consortium. The network is represented in a GML file named hep-th.gml. Your goal is to employ the Infomap algorithm from the cdlib library to detect communities within this network. Furthermore, you're expected to provide a JSON representation of the identified communities to aid in decision-making and resource allocation for collaborative research efforts.
### Response:
from cdlib import algorithms
import networkx as nx

# Load the graph from the High-energy theory collaborations file
G = nx.read_gml('hep-th.gml')

# Perform community detection using the Infomap algorithm
communities = algorithms.infomap(G)

# Convert the communities to a JSON representation and print
communities_json = communities.to_json()
print(communities_json)
