title: How to import NumPy as a module into Eclipse (PyDev)
body: <p>I'm trying to use NumPy in Eclipse, in which I'm using Python 3.4 and PyDev.  I have installed NumPy version 1.9.2 (with setup.py) and it works fine in IDLE </p>
  
  <pre><code>&gt;&gt;&gt;import numpy as np
  &gt;&gt;&gt;a = np.array([0,1,2,3])
  &gt;&gt;&gt;print(a)
  [0 1 2 3]
  </code></pre>
  
  <p>but when I do the same thing in Eclipse I get an error <code>No Module named 'numpy'</code></p>
  
  <p>I have already gone to Preferences > PyDev > Interpreters > Python Interpreter > Libraries</p>
  
  <p>and added the NumPy location <code>/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/numpy</code> and restarted my machine.</p>
  
  <p>I'm at a loss for what to try next, do I need to delete and reconfigure all of PyDev in order for this to work?</p>
