<｜begin▁of▁sentence｜>### Instruction:
As a fire inspector, your task is to assess the fire risks and hazards within a specific building and ensure that it complies with fire codes, regulations, and safety standards. Using the information provided in the 'network.graphml' file, you need to calculate the "PageRank" values for the building's systems, considering them as a directed graph and applying a damping factor of 0.85. This will help you prioritize and address any potential fire safety concerns within the building.
### Response:
import igraph as ig

# Load the graph from a GraphML file
g = ig.Graph.Read_GraphML('network.graphml')

# Calculate PageRank scores for all vertices
damping_factor = 0.85
page_rank_scores = g.pagerank(directed=True, damping=damping_factor)

# Print the PageRank scores
print(page_rank_scores)
