<｜begin▁of▁sentence｜>### Instruction:
Given the Condensed matter collaborations 2005 Graph which you can read from a gml file named cond-mat-2005.gml, can you use the spectral function in cdlib to perform community detection, aiming to find two communities? Can you then convert and print the community detection result into a JSON format?
### Response:
import networkx as nx
from cdlib import algorithms

# Load a graph from a gml file
g = nx.read_gml('cond-mat-2005.gml')

# Apply spectral clustering for community detection
# Here, we set kmax to 2 to get two communities as an example
communities = algorithms.spectral(g, kmax=2)

# Convert the clustering to JSON representation
clustering_json = communities.to_json()

print(clustering_json)
