title: Can't reshape numpy array
body: <p>I have a function that is supposed to take a 1D array of integers and shapes it into a 2D array of 1x3 arrays. It then is supposed to take each 1x3 array and shift it into a 3x1 array. The result is supposed to be a 2D array of 3x1 arrays. Here is my function</p>
  
  <pre><code>def RGBtoLMS(rgbValues, rgbLength): #Method to convert from RGB to LMS
      print rgbValues
      lmsValues = rgbValues.reshape(-1, 3)
      print lmsValues
      for i in xrange(len(lmsValues)):
          lmsValues[i] = lmsValues[i].reshape(3, 1)
  
      return lmsValues
  </code></pre>
  
  <p>The issue rises when I try to change the 1x3 arrays to 3x1 arrays. I get the following output assuming rgbValues = [14, 25, 19, 24, 25, 28, 58, 87, 43]</p>
  
  <pre><code>[14 25 19 ..., 58 87 43]
  [[14 25 19]
   [24, 25, 28]
   [58 87 43]]
  
  ValueError [on line lmsValues[i] = lmsValues[i].reshape(3, 1)]: could not broadcast input array from shape (3,1) into shape (3)
  </code></pre>
  
  <p>How can I avoid this error?</p>
