Option to only dump random walks to disk and skip training

[viveksck]

gensim version downgraded to 0.10.1 as 0.10.2 does not install via easy_install due to this bug: https://groups.google.com/forum/#!topic/gensim/NSOXuP4IE9Q

In [1]: import gensim

In [2]: gensim.version
Out[2]: '0.10.1'

vvkulkarni@descartes:~/deepwalk$ deepwalk --input ./example_graphs/karate.adjlist --output karate.embeddings
Number of nodes: 34
Number of walks: 340
Data size (walks*length): 13600

This is the solution I used in polyglot

Pushing in changes to only dump walks if needed. Change needed for extended work.

vvkulkarni@curie:/toolkits/viveks_deepwalk/deepwalk$ deepwalk --input example_graphs/karate.adjlist --output karate.embeddings --max-memory-data-size 0
Number of nodes: 34
Number of walks: 340
Data size (walks_length): 13600
Data size 13600 is larger than limit (max-memory-data-size: 0). Dumping walks to disk.
