hsplits = [49]
sum_hsplits = 49
while sum_hsplits < 512:

hsplits.append(sum_hsplits)
sum_hsplits += 59


np.split(np.random.rand(512), hsplits)

If I understand correctly, this is a one-dimensional version of what you
want. Extending this to the second dimension should be quite easy.
However, I am not sure if I do understand what you want. Could
you elaborate on what you are trying to achieve?
