title: windows, ImportError: DLL load failed: The specified module could not be found
body: <pre><code>import numpy as np
  import cv2
  from matplotlib import pyplot as plt
  
  img = cv2.imread('12.jpg',0)
  orb = cv2.ORB()
  kp = orb.detect(img,None)
  kp, des = orb.compute(img, kp)
  img2 = cv2.drawKeypoints(img,kp,color=(0,255,0), flags=0)
  plt.imshow(img2),plt.show()
  </code></pre>
  
  <p>I have added the <code>numpy</code> and <code>cv2</code> modules to my python directory and set their environment variables. </p>
  
  <p>I also installed <code>msvcp71.dll</code> and <code>msvcr71.dll</code>, but this error has not solved. </p>
  
  <p>So how can i fix this kind of dll problem?</p>
