<｜begin▁of▁sentence｜>### Instruction:
As an Emergency Medical Dispatcher, you have received a request from a major sporting event for emergency services to be on standby. In order to efficiently manage and analyze the data, you are required to convert the node labels in the American College Football Graph, which has been provided in a GML file named football.gml, from strings to integers while maintaining a mapping back to the original string labels. This will enable your team to analyze and understand the network connections more effectively during the event.
### Response:
import networkx as nx
from cdlib.utils import convert_graph_formats

# Load the American College football graph
G = nx.read_gml('football.gml')

# Apply nx_node_integer_mapping to convert node labels to integers
integer_graph, mapping, _ = convert_graph_formats.nx_node_integer_mapping(G)

# Now integer_graph has integer node labels, and mapping contains the original node labels
