freebase vector file in python gensim

```
What steps will reproduce the problem?
1. Load freebase.bin files into a word2vec model on freebase
2. attempy .most_similar function
3. error returned

What is the expected output? What do you see instead?
see beloe

What version of the product are you using? On what operating system?
mac osx anaconda python

Please provide any additional information below.

I’m trying to get started by loading the pretrained .bin files from the
google word2vec site ( freebase-vectors-skipgram1000.bin.gz) into the gensim
implementation of word2vec. The model loads fine,

using ..

model = word2vec.Word2Vec.load_word2vec_format('...../free....-en.bin', binary=
True)
and creates a

>>> print model

but when I run the most similar function. It cant find the words in the
vocabulary. My error code is below.

Any ideas where I’m going wrong?

>>> model.most_similar(['girl', 'father'], ['boy'], topn=3)

any ideas welcome?

Start by reproducing the reported load and model.most_similar calls with the freebase-vectors-skipgram1000.bin.gz file and gensim 0.8.7 on the stated Anaconda/macOS setup. Inspect gensim/models/word2vec.py around most_similar and load_word2vec_format; done means identifying why the loaded vocabulary does not contain girl, father, or boy and documenting or correcting the supported loading behavior.
