Multidimensional indexing in numpy array

Question

Let's suppose I have an image such that

image.shape=(280,280,3)

If I do img[[[1,2],[1,2],[1,2]]].shape, I obtain (2,). But I expect to obtain (2,2,2)...

How can slicing be performed simultaneously on several dimensions in numpy?

You are using the Array of Indices syntax, when you probably want slices.

Try something like this:

img[1:3, 1:3, 1:3]
