Same here:

cnt, _ = cv2.findContours(canny, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)
print cnt.size, cnt.shape, cnt.dtype
cnt_len = cv2.arcLength(cnt, True)

Crash while saying:

""" 
68 (34, 1, 2) int32
Traceback (most recent call last):
    cnt_len = cv2.arcLength(cnt, True)
TypeError: curve data type = 5 is not supported
