<｜begin▁of▁sentence｜>### Instruction:
Given the Astrophysics collaborations graph which you can read from a GML file named astro-ph.gml, can you use the EnDNTM algorithm in cdlib to perform overlapping community detection based on ensemble approaches with distributed neighbourhood threshold methods? Also, can you provide a JSON representation of the resulting NodeClustering object?
### Response:
from cdlib import algorithms
import networkx as nx

# Load an Astrophysics collaborations graph
G = nx.read_gml('astro-ph.gml')

# Compute base partition using crisp community detection algorithms
base_partitions = [algorithms.louvain(G), algorithms.label_propagation(G), algorithms.walktrap(G)]

# Use EnDNTM to detect overlapping communities based on the base partitions
overlapping_communities = algorithms.endntm(G, base_partitions)

# Convert the NodeClustering object to a JSON format
communities_json = overlapping_communities.to_json()

# Output the JSON object
print(communities_json)
