<｜begin▁of▁sentence｜>### Instruction:
Given the Adjacency noun Graph which you can read from a gml file named adjnoun.gml, can you use the walktrap function in cdlib to perform community detection? Could you then convert the resulting communities into a JSON format?
### Response:
import networkx as nx
from cdlib import algorithms

# Loading the graph
G = nx.read_gml('adjnoun.gml')

# Performing community detection using Walktrap algorithm
communities = algorithms.walktrap(G)

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

print(communities_json)
