title: ImportError: No module named numpy
body: <p>I'm trying to run a program that requires Numpy to be installed. I thought it was, because if I try <code>sudo apt-get install python-numpy</code> it tells me that</p>
  
  <pre><code>sudo apt-get install python-numpy
  
  Reading package lists... Done
  Building dependency tree       
  Reading state information... Done
  python-numpy is already the newest version.
  0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
  </code></pre>
  
  <p>But then when I go to install the program I'm trying to (within that programs directory, where setup.py is located) I get:</p>
  
  <pre><code>python setup.py install
  Traceback (most recent call last):
     File "setup.py", line 20, in &lt;module&gt;
      from weblogolib import __version__
    File "/home/chris/Documents/IS/Bioinformatics-Software/weblogo-3.3/weblogolib/__init__.py", line 108, in &lt;module&gt;
       from numpy import array, asarray, float64, ones, zeros, int32,all,any, shape
  ImportError: No module named numpy
  </code></pre>
  
  <p>When I look in the Python-2.7.3/Lib/site-packages directory the only thing that's in there is a README file. Shouldn't there be stuff from Numpy in there (and other install Python modules)?</p>
  
  <p>I am running Ubuntu 12.04 with Python 2.7</p>
  
  <p>Using <code>dpkg -l python-numpy</code> I get:</p>
