<｜begin▁of▁sentence｜>### Instruction:
Given the Internet AS graph which you can read from a GML file named as-22july06.gml, can you use the spectral clustering community detection algorithm in cdlib to perform community detection specifying the maximum number of desired communities to be 2? Can you also generate a JSON representation of the detected communities?
### Response:
import networkx as nx
from cdlib import algorithms

# Load the Internet Graph from a GML file
G = nx.read_gml('as-22july06.gml')

# Perform community detection using the Spectral Clustering algorithm
# specifying the maximum number of desired communities
communities = algorithms.spectral(G, kmax=2)

# Generate a JSON representation of the detected communities
communities_json = communities.to_json()
print(communities_json)
