I have a huge graph with about 5000 nodes that I made it with networkX. It takes about 30 seconds to create this graph each time I execute my script. After this relatively long time I can run my analysis like shortest_path and so on.
My question is, is there any way to store the object of this graph in file or something like this and each time I run my script, networkX read that file and load all of my graph?
You could use gpickle to do this. Assuming your graph is denoted with G, you could save it by:
nx.write_gpickle(G,'myGraph.gpickle')
and load it with
G = nx.read_gpickle('myGraph.gpickle')
https://networkx.org/documentation/stable//reference/readwrite/gpickle.html#pickled-graphs
As of version 2.6, methods write_gpickle and read_gpickle are deprecated. Try this instead:
import pickle
# save graph object to file
pickle.dump(G, open('filename.pickle', 'wb'))
# load graph object from file
G = pickle.load(open('filename.pickle', 'rb'))
Note the options 'wb' to dump and 'rb' to load in open().
