title: ImportError: numpy.core.multiarray failed to import
body: <p>I'm trying to run this program</p>
  <pre><code>import cv2
  import time
  
  cv.NamedWindow(&quot;camera&quot;, 1)
  
  capture = cv.CaptureFromCAM(0)
  
  while True:
      img = cv.QueryFrame(capture)
      cv.ShowImage(&quot;camera&quot;, img)
      if cv.WaitKey(10) == 27:
          break
  cv.DestroyAllWindows()
  </code></pre>
  <p>But I'm having a problem with numpy, I'm using pyschopy along with opencv.
  The problem I keep getting is this error report:</p>
  <blockquote>
  <p>RuntimeError: module compiled against API version 7 but this version of numpy is 6</p>
  <p>Traceback (most recent call last):</p>
  <p>File &quot;C:\Users\John\Documents\EyeTracking\Programs\GetImage.py&quot;, line 1, in</p>
  
  <pre><code>import cv2
  </code></pre>
  <p>ImportError: numpy.core.multiarray failed to import</p>
  </blockquote>
  <p>I have numpy-1.6.1-py2.7 in the psychopy folder, I'm just confused as to what is wrong?</p>
