<｜begin▁of▁sentence｜>### Instruction:
Given a graph stored in a pickle file 'path_to_pickled_graph.pkl', can you read the graph using igraph's Read_Pickle function and calculate the average path length of the graph?
### Response:
from igraph import Graph

# Read a graph from a pickle file
file_path = 'path_to_pickled_graph.pkl'
g = Graph.Read_Pickle(fname=file_path)

# Calculate the average path length of the graph
avg_path_length = g.average_path_length()
print(f'Average path length: {avg_path_length}')
