Pickles are a serialized byte stream of a Python object . This format will preserve Python objects used as nodes or edges.
- G (graph) – A NetworkX graph
- path (file or string) – File or filename to write. Filenames ending in .gz or .bz2 will be compressed.
- protocol (integer) – Pickling protocol to use. Default value:
>>> G = nx.path_graph(4) >>> nx.write_gpickle(G, "test.gpickle")
