I have huge list of int32 numpy 1d arrays. Is there an efficient way to get indexes of rows having non-empty intersection with test array? Basically I'm looking for faster replacement for pythonic expression:
indexes = [
i for i, n in enumerate(iterable_of_iterables) # [[1, 2], [2, 3], [4]]
if set(n).intersection(test_iterable) # [1, 4]
] # -> [0, 2]
