title: Resource 'corpora/wordnet' not found on Heroku
body: <p>I'm trying to get NLTK and wordnet working on Heroku. I've already done</p>
  
  <pre><code>heroku run python
  nltk.download()
    wordnet
  pip install -r requirements.txt
  </code></pre>
  
  <p>But I get this error:</p>
  
  <pre><code>Resource 'corpora/wordnet' not found.  Please use the NLTK
    Downloader to obtain the resource:  &gt;&gt;&gt; nltk.download()
    Searched in:
      - '/app/nltk_data'
      - '/usr/share/nltk_data'
      - '/usr/local/share/nltk_data'
      - '/usr/lib/nltk_data'
      - '/usr/local/lib/nltk_data'
  </code></pre>
  
  <p>Yet, I've looked at in /app/nltk_data and it's there, so I'm not sure what's going on.</p>
