Most similar query takes forever

[bbryndak]

I am trying to use pymagitude on Ubuntu virtual machine, but i hit the following problem with the medium dataset:

import pymagnitude

if __name__=="__main__":
    word2vec = pymagnitude.Magnitude('data/GoogleNews-vectors-negative300.magnitude')
    print(word2vec.query('cat'))
    print(word2vec.most_similar('cat', topn=20))
    word2vec.close()

The normal queries seem to work without issues, but when I try to use the most_similar query, it never completes. The same problem occurs with large dataset and most_similar_approx query. I have tried to change lazy_loading and eager arguments, but it didn't help. Any ideas on what could be the problem?
