tiling a multi-dimensional numpy array into a lower dimensional array

Question

I have a (100,128,128) shaped array and want to convert it into a (1280,1280) array. Actually (128,128) is the size of the images and there are 100 of them. I want to tile all images on a single grid like

im1 im2 im3 ... im10

im11 im12 im13 ... im20

and so on.

reshape to (10,10,128,128). Transpose some axes, and reshape to the target shape. — hpaulj, Jun 14 '20 at 19:24
`images.reshape(10,10,128,128).swapaxes(2,1).reshape(1280,1280)` works like a charm. Thanks. — colt.exe, Jun 14 '20 at 20:19

Assuming arr is your array:

arr=np.broadcast_to(arr,(128,128,100))
arr.reshape(1280,1280)
