<｜begin▁of▁sentence｜>### Instruction:
Given a graph which you can read from network.gml, can you use the 'summary' method of the 'Cover' class in igraph to return a summary of the community structure detected in the graph? The summary should include the number of items, the number of clusters, and the list of members for each of the clusters (with verbosity set to 1).
### Response:
from igraph import Graph
import igraph as ig

# Read the graph
graph = ig.read('network.gml')

# Perform community detection to get a cover object
cover = graph.community_walktrap().as_cover()

# Get the summary of the cover
summary = cover.summary(verbosity=1)
print(summary)
