title: Force gensim's word2vec vectors to be positive?
body: <p>Is there any way in gensim that i can force the learned vectors in word2vec to be all positive? (all the elements of vector be positive). i am working on a different task that needs these vectors to be positive ( the reason is really complicated so don't ask why )</p>
  <p>so what is the easiest way for me to force gensim to learn positive vectors?</p>
