Issue with gensim 4.0.0+

[hhu1]

Following bash command worked for me:

pip3 install -I gensim==3.8.0

Thanks.

I can make a patch that checks the gensim version for now and routes the argument depending on the version.

Long term the idea would be to remove the gensim dependency entirely. It's a heavy dependency that's a moving target and only used for this one part of Node2Vec.

It has a lot of overhead for Node2Vec. For one, we need to map nodenames back from random walks to a format gensim accepts.

We could just train a word2vec model directly on the nodeIDs (ints, so would be faster) and re-map the embedding dictionary keys from nodeID -> node name only once after everything is trained.

This could be achieved either by stripping the node2vec C code and integrating it in CSRGraphs or by using another C/C++ implementation, like this one:

https://github.com/xgfs/node2vec-c

(which works on CSR representation already, not too far from csrgraphs) or this one:

https://github.com/snap-stanford/snap/tree/master/examples/node2vec

and integrating it into CSRGraphs.

Following bash command worked for me:

pip3 install -I gensim==3.8.0

That did not solve my problem. It is still there
