title: Keras not working with python3
body: <p>When I trying to install keras with pip3 this message shows.</p>
  
  <pre><code>Requirement already satisfied: keras in /usr/local/lib/python3.5/dist-packages
  Requirement already satisfied: pyyaml in /usr/local/lib/python3.5/dist-packages (from keras)
  Requirement already satisfied: six&gt;=1.9.0 in ./.local/lib/python3.5/site-packages (from keras)

  </code></pre>
  
  <p>But I import keras in a project it shows this error.</p>
  
  <pre><code>Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
  ModuleNotFoundError: No module named 'keras'
  </code></pre>
  
  <p>How to solve this problem? I used Ubuntu 16.04 and python 3. </p>
