  You are using pip version 7.1.2, however version 8.1.2 is available.
  You should consider upgrading via the 'pip install --upgrade pip' command.
  </code></pre>
  
  <p>But when I tried <code>pip3 install --upgrade pip3</code>, it returns,</p>
  
  <pre><code>Could not find a version that satisfies the requirement pip3 (from versions)
  No matching distribution found for pip3
  </code></pre>
  
  <p>I do know there is a collision with python2 and python3 when executing the setup.py file but I don't know how to solve this problem to run correctly so please help me.</p>
