This seems to work fine with small model such as that produced by
demo_word.sh in the word2vec code repository however I get problems when trying
a large model such as
[GoogleNews-vectors-negative300.bin](https://drive.google.com/file/d/0B7XkCwpI5KDYNlNUTTlSS21pQmM/edit?usp=sharing).
I can successfully load the model using this code (albeit I needed to give
the driver 12GB of memory):
`import org.apache.spark.ml.feature.Word2VecModel`
`val path = "file:///Downloads/GoogleNews-vectors-negative300.bin"`
`val model = Word2VecModel.loadGoogleModel(path)`
However synonyms are not found for a typical lookup e.g.
`model.findSynonyms("spark",20).show`
responds with
`java.lang.IllegalStateException: spark not in vocabulary`
However the distance tool from the word2vec toolkit, loading the same model
gives:
