In this tutorial, there is a function preparing the image as below:
`def prep_image(img, inp_dim):
"""
Prepare image for inputting to the neural network.
We use this line to reverse the final dim of img and transpose it:
img = img[:,:,::-1].transpose((2,0,1)).copy()
I know that we transpose it because we want the channels in order of RGB. But why should we reverse it first?
