title: Normalize vectors in gensim model
body: <p>I have a pre-trained word embedding with vectors of different norms, and I want to normalize all vectors in the model. I am doing it with a for loop that iterates each word and normalizes its vector, but the model us huge and takes too much time. Does <code>gensim</code> include any way to do this faster? I cannot find it.</p>
  <p>Thanks!!</p>
