type error array

[BrianPA]

I have a numpy 2darray called d5. I'm trying to get values from row#1 [0]. and I'm comparing them with values from row#2 [1]. If values from row#2 are not equal, then advance to row#3 and iterate until you find a match. Here is the code that is throwing an error for me, along with the error message it self. Bare with me cause i'm really a newbie, and there may be ALOT wrong with what I'm doing!

    lay_1 = 1
    a = 0
    b = lay_1
    del5_counter = 0
    draw_del5 = np.array(d5[a][1] - d5[a][0], d5[a][2] - d5[a][1], d5[a][3] - d5[a][2], d5[a][4] - d5[a][3])
    for row in d5:
        del5_1 = np.array(d5[b][1] - d5[b][0], d5[b][2] - d5[b][1], d5[b][3] - d5[b][2], d5[b][4] - d5[b][3])
        if del5_1 != draw_del5:
            b += 1
            del5_counter += 1
        else:
            break
