title: No module named 'pandas' in Pycharm
body: <p>I read all the topics about, but I cannot solve my problem:</p>
  <pre><code> Traceback (most recent call last):
   File &quot;/home/.../.../.../reading_data.py&quot;, line 1, in &lt;module&gt;
   import pandas as pd
   ImportError: No module named pandas     
  </code></pre>
  <p>This is my environment:</p>
  <p>Ubuntu 14.04</p>
  <p>Pycharm version: 2016.1.4</p>
  <p>Python version: 2.7.10</p>
  <p>Pandas version: 0.18.1</p>
  <p>Pandas works in Anaconda, in Jupyter too. How to fix the problem?</p>
