<｜begin▁of▁sentence｜>### Instruction:
As a Postpartum Doula who provides physical, emotional, and informational support to new mothers and families during the postpartum period, imagine being asked to assist a group of researchers who recently conducted a study on community structures in an Internet Autonomous Systems graph. They have the data stored in a GML file named as-22july06.gml. They are specifically looking to leverage the Louvain method available in the cdlib API to perform community detection on the graph and determine the size of the communities. Your task is to help them by executing the community detection process and reporting back the sizes of the detected communities.
### Response:
import networkx as nx
from cdlib import algorithms, evaluation

# Create a graph from Internet autonomous systems
G = nx.read_gml('as-22july06.gml')

# Apply the Louvain method for community detection
communities = algorithms.louvain(G)

# Compute the size of the communities
size = evaluation.size(G, communities)

print(size)
<|EOT|>
