title: Python 3.5 No Module named xlrd or pybrain
body: <p>I am working on a project to build a Neural Net in python from an xlrd file, and I am encountering some issues. I have installed xlrd using pip install xlrd, and pybrain by cloning the git repository and running <code>python setup.py install</code> both of which were successful in installing. When I try to run <code>import xlrd</code> or <code>import pybrain</code> from IDLE, it gives the error:</p>
  
  <pre><code>&gt;&gt;&gt; import xlrd
  Traceback (most recent call last):
  File "&lt;pyshell#0&gt;", line 1, in &lt;module&gt;
      import xlrd
  ImportError: No module named 'xlrd'
  </code></pre>
  
  <p>and the same thing for pybrain. I only have python 3.5 installed. I am at the end of my rope with this, If anyone can give some insight in to why this may be happening I would be very appreciative. </p>
