<｜begin▁of▁sentence｜>### Instruction:
Given the High-energy theory collaborations graph which you can read from a GML file named hep-th.gml, can you use the Infomap function in cdlib to perform community detection? Additionally, can you provide a JSON representation of the detected communities?
### 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)
