title: unknown URI scheme while opening bin file
body: <p>Using Python 3.5, I try to open .bin file with Word2Vec representations  downloaded from source <a href="http://ling.go.mail.ru/static/models/ruscorpora_russe.model.bin.gz" rel="nofollow noreferrer">http://ling.go.mail.ru/static/models/ruscorpora_russe.model.bin.gz</a></p>
  
  <p>Doing it with the following code </p>
  
  <pre><code>import gensim.models 
  Word2Vec = gensim.models.KeyedVectors.load_word2vec_format('D://ruscorpora.model.bin', binary=True)
  </code></pre>
  
  <p>I get an error.</p>
  
  <p><strong>NotImplementedError: unknown URI scheme 'd' in 'D://ruscorpora.model.bin'</strong></p>
  
  <p>How can I tackle this problem?</p>
