[QST]: Saving cugraph object

[acjones27]

What is your question?

Hi,

I was wondering if anyone knows how to save a Graph object after it's been created? I'm creating a large DiGraph (1.7 billion edges), so I would preferably like to save the output once it has been created. Is this possible? I looked into pickle and joblib but got errors "cannot pickle 'socket' object" and "TypeError: cannot pickle 'TaskStepMethWrapper' object", respectively

You can get the edge data from the graph, which is a cuDF DataFrame and then use the save features offered by cuDF.
cuDF support saving as CSV, Parquet, JSON, or ORC. https://docs.rapids.ai/api/cudf/stable/user_guide/io.html

Hi @BradReesWork, thanks for the suggestion. Could you be more specific about the edge data? Do you mean the edgelist? If so, wouldn't I still have to rebuild the graph from scratch each time? Also, I already have the edge data since that's how I built the graph to begin with so I guess it's the same thing (apologies if I'm missing something)
