Node2Vec in a large graph

[VHRanger]

If you absolutely insist on running Node2Vec, I'd recommend modifying the settings in the Node2Vec class like this

 nodevectors.Node2Vec(
        walklen=20, 
        epochs=5,
        return_weight=1.,
        neighbor_weight=1.,
        threads=1, 
        verbose=True
)

Segfaults are generally related to threading (so using threads != 1 ) with using return_weight or neighbor_weight different than 1. If you keep threads to 1 and walk weights to default settings it shouldn't segfault.

You can always try some of the other embedding algorithms (GGVec, GraRep, ProNE) -- Node2Vec is the only one that has this segfault issue and it's been hard to replicate and find the cause as of yet. Node2Vec is also not particularly better than the other ones, it's just more well known.

To help with the segfault, can you send me your setup? Your computer, python, numpy, numba version the Node2Vec settings used and either a link to your graph data or some statistics on it (directed or undirected, number of nodes and edges, etc.)

Thanks

Since this isn't being expanded upon, and I can't replicate it, I'll close the issue.

Please message me or reopen an issue if you run into anything, or this persists
