<｜begin▁of▁sentence｜>### Instruction:
Given the Word Adjacencies Graph from a GML file named adjnoun.gml, can you compare two community detection results obtained by using the Louvain and Leiden algorithms? Specifically, please compute the Overlapping Normalized Mutual Information using the variant proposed by McDaid, A. F., Greene, D., & Hurley, N. (2011) to evaluate the similarity between the community structures detected by these two algorithms.
### Response:
import networkx as nx
from cdlib import algorithms, evaluation

# Load an example graph from a gml file
G = nx.read_gml('adjnoun.gml')

# Perform community detection using two different algorithms
louvain_communities = algorithms.louvain(G)
leiden_communities = algorithms.leiden(G)

# Evaluate the similarity of the two detected community structures
onmi_score = evaluation.overlapping_normalized_mutual_information_MGH(louvain_communities, leiden_communities)

# Output the Overlapping Normalized Mutual Information score
print(onmi_score.score)
