title: Store networkx graph object
body: <p>I have a huge graph with about 5000 nodes that I made it with <a href="https://networkx.org/" rel="nofollow noreferrer">networkX</a>. 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 <code>shortest_path</code> and so on.</p>
  <p>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?</p>
