title: How to feed OpenCV image to a trained CNN model(add a new dimension) in Python?
body: <p>I'm getting this error <code>Error when checking input: expected conv2d_11_input to have 4 dimensions, but got array with shape (300, 300, 3)</code>
  How can I pass the RGB image to a CNN? How to enumerate samples to create a 4D image? </p>
