NumPy + PyTorch Tensor assignment
lets assume we have a tensor representing an image of the shape (910, 270, 1) which assigned a number (some index) to each pixel with width=910 and height=270. We also have a numpy array of size (N, 3) which maps a 3-tuple to an index. I now want to create a new numpy array of shape (920, 270, 3) which
