<｜begin▁of▁sentence｜>### Instruction:
Given the Adjacency nouns Graph which you can read from a GML file named adjnoun.gml, can you use Louvain and Leiden functions in cdlib to perform community detection? And can you compute the Variation of Information to measure the similarity between the community structures obtained by these two methods? Notes: You need to print the Variation of Information for the community structures.
### Response:
import networkx as nx
from cdlib import algorithms, evaluation

# Read the graph structure
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 community structures found by the two algorithms
vi = evaluation.variation_of_information(louvain_communities, leiden_communities)
print(vi)
