title: from visual import * not working (vpython)
body: <p>I just downloaded <code>vPython</code> for <code>Python 2.7.9</code> and got the following error when importing the <code>.visual</code> library:</p>
  
  <pre><code>Traceback (most recent call last):
      File "Untitled", line 1
          from visual import *
      File "C:\Python27\Lib\site-packages\visual\__init__.py", line 3
          from visual.visual_all import * # this statement not included in vis/__init__.py
      File "C:\Python27\Lib\site-packages\visual\visual_all.py", line 10
          from visual_common.cvisual import vector
  ImportError: numpy.core.multiarray failed to import
  </code></pre>
  
  <p>To avoid confusion I tried reinstalling both <code>Python</code> and <code>vPython</code> and made sure that it is the 64-bit version.<br>
  I don't know if it's an issue with my <code>python27</code> files or if I downloaded it wrong. Does anyone know how to solve the error?</p>
