title: AttributeError: 'list' object has no attribute 'words' in python gensim module
body: <p>While training using <code>doc2vec</code>, I got this error:</p>
  
  <pre><code>AttributeError: 'list' object has no attribute 'words' in python gensim module
  </code></pre>
  
  <p>This is my code:</p>
  
  <pre><code># Extracting titles from csv to list
  with open(query+'_titles.csv', 'rb') as f:
      reader = csv.reader(f)
      titlelist = list(reader)
  # build
  model = doc2vec.Doc2Vec(size=30, window=1, alpha=0.01, min_count=2, sample=1e-5, workers=100)
  model.build_vocab(titlelist)
  titlearray = np.asarray(titlelist)
  print 'Training Model...'
  </code></pre>
  
  <p>I use python <em>2.7.11</em> and gensim version is <em>3.2.0</em> if that helps. There must be something I am really missing. </p>
