<｜begin▁of▁sentence｜>### Instruction:
Given two sets of community clusterings of a network, with 'clustering1' and 'clustering2' representing these sets, how would you use igraph to compare these two clusterings using the variation of information method?
### Response:
import igraph as ig

# Assume 'clustering1' and 'clustering2' are two Clustering objects already computed
# For instance, these could be the results of some community detection algorithm
similarity = clustering1.compare_to(clustering2, method='vi')
print('Similarity (variation of information):', similarity)
