title: TypeError: '<' not supported between instances of 'SetuptoolsVersion' and 'SetuptoolsVersion'
body: <p>I'm using Google NLP API and I'm trying to run the entity_sentiment_text function in the snippets.py script (<a href="https://github.com/GoogleCloudPlatform/python-docs-samples/blob/master/language/cloud-client/v1/snippets.py" rel="nofollow noreferrer">https://github.com/GoogleCloudPlatform/python-docs-samples/blob/master/language/cloud-client/v1/snippets.py</a>) but I get this error:</p>
  
  <pre><code>TypeError: '&lt;' not supported between instances of 'SetuptoolsVersion' and 
  'SetuptoolsVersion'
  </code></pre>
  
  <p>Apparently it is raised in _cryptography_rsa.py</p>
  
  <p>Thank you for your help</p>
