<｜begin▁of▁sentence｜>### Instruction:
Given the Political blogs Graph which you can read from a GML file named polblogs.gml, can you use the rber_pots function in cdlib with a specific resolution parameter to perform community detection and output a JSON representation of the NodeClustering object?
### Response:
import networkx as nx
from cdlib import algorithms

# Read the graph from polblogs.gml file
G = nx.read_gml('polblogs.gml')

# Apply the rber_pots algorithm for community detection with a specific resolution parameter
coms = algorithms.rber_pots(G, resolution_parameter=1.5)

# Convert the NodeClustering object to its JSON representation
coms_json = coms.to_json()

print(coms_json)
