<｜begin▁of▁sentence｜>### Instruction:
Given the Les Misérables Graph which you can read from a gml file named lesmis.gml, can you use the CONGO algorithm in cdlib to perform community detection? The number of communities desired is set to 3 and the height is set at 2. Afterwards, can you convert the identified communities into a JSON format?
### Response:
import networkx as nx
from cdlib import algorithms

# Load the Les Miserables graph
G = nx.read_gml('lesmis.gml')

# Apply the CONGO algorithm to identify communities
# with the number of communities set to 3 and height to 2
communities = algorithms.congo(G, number_communities=3, height=2)

# Convert the communities to a JSON object
communities_json = communities.to_json()

# Print the communities in JSON format
print(communities_json)
