Then I have another numpy array of for example 10*2*10 (200 elements). I want to know if in the bigger dataset of 100*100*100, there is anywhere, where the second numpy array of 200 elements with shape 10*2*10 appears. If it does, then I want the indices of the bigger dataset where this happens. >
So you want to find N in M. First find all occurrences of N[0][0][0] in M[:90][:98][:90]. Then for each of those extract the same size subview from M and check if (Ms == N).all(). -- Oscar -- https://mail.python.org/mailman/listinfo/python-list
