<｜begin▁of▁sentence｜>### Instruction:
Given the Books about US politics graph which you can read from a GML file named polbooks.gml, can you use the IPCA community detection algorithm from cdlib on it? And can you generate a JSON representation of the resulting IPCA object?
### Response:
from cdlib import algorithms
import networkx as nx

# Reading the graph from a GML file
G = nx.read_gml('polbooks.gml')

# Running IPCA algorithm for community detection
coms = algorithms.ipca(G)

# Generating a JSON representation of the IPCA object
coms_json = coms.to_json()
print(coms_json)
