Check if two numpy arrays are identical

Question

Suppose I have a bunch of arrays, including x and y, and I want to check if they\'re equal. Generally, I can just use np.all(x == y) (

Answer 1

Hmmm, I know it is the poor answer but it seems there is no easy way for this. Numpy Creators should fix it. I suggest:

def compare(a, b):
    if len(a) > 0 and not np.array_equal(a[0], b[0]):
        return False
    if len(a) > 15 and not np.array_equal(a[:15], b[:15]):
        return False
    if len(a) > 200 and not np.array_equal(a[:200], b[:200]):
        return False
    return np.array_equal(a, b)
