title: ValueError: cannot reshape array of size 6744500 into shape (574,1,64,47)
body: <p>I'm using fetch_lfw_people from sklearn to get the faces to recognize and but when I trat to reshape II get this error  <code>ValueError: cannot reshape array of size 6744500 into shape (574,1,64,47)</code> but for the data that I have It seems like the correct parameters ,is the image size that says the doc <a href="http://scikit-learn.org/stable/modules/generated/sklearn.datasets.fetch_lfw_people.html" rel="nofollow noreferrer">doc</a>
  I know 574*1*64*47 is not 6744500 but is the data that I have</p>
  
  <pre><code>lfw_people = fetch_lfw_people(min_faces_per_person=200, resize=1)
  X = lfw_people.data
  y = lfw_people.target
  X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.25)
  
  X_train = X_train.reshape(X_train.shape[0], 1, 64, 47).astype('float32')
  X_test = X_test.reshape(X_test.shape[0], 1, 64, 47).astype('float32')
  </code></pre>
