title: Gensim package installation/word2vec not recognised
body: <p><code>from gensim.models import Word2Vec</code></p>
  <p>results in the following error
  ImportError: cannot import name 'Word2Vec' from 'gensim.models' (unknown location)</p>
  <p><code>from gensim.models.word2vec import Word2Vec</code></p>
  <p>results in the same error</p>
  <p>After deleting all conda installations of this package, pip uninstalling gensim, pip installing gensim and pip install --upgrade gensim, I can finally do</p>
  <p><code>import gensim</code>
  but when I try to use <code>gensim.models.Word2Vec</code> it results in the error:
  AttributeError: module 'gensim.models' has no attribute 'Word2Vec'</p>
  <p>Edit: updated Numpy and Scipy as well</p>
  <p>Note: I am using a jupyter notebook that I run from my local machine. I have not had this problem using Pycharm where I was running gensim from a conda env (but I'm working on a group project in notebook so it would be nice if I didn't constantly have to copy paste between these 2 workspaces...)</p>
  <p>Any help would be appreciated</p>
