Hello , I'm getting error, nothing found with search,
I've problem with cv.Moments() on line 61, it seems depreciated , how should i fix ? which openCV should i install ?
moment = cv.Moments(points) i've replace above line with : moment = cv2.moments(points)
but another error occurred:
File "./crop_plates.py", line 61, in get_box moment = cv2.moments(points)
TypeError: array is not a numpy array, neither a scalar

I'm having a problem with this, I randomly guess the value of template_max_width_px = 163 template_max_height_px = 63 I don't know what to consider about this, would you help me?
