Я хочу обнаружить игральные карты и найти .cfg и .weights для него. Классы имеет 52 карты имен. Следующий код дает индекс ошибки вне диапазона. Я не мог понять результаты Yolo и как получить обнаруженные ярлыки. Я новичок в этом, пытался понять. Может кто-нибудь, пожалуйста, помогите!

with open("cards.names", "r") as f:
classes = [line.strip() for line in f.readlines()]
layer_names = net.getLayerNames()
output_layers = [layer_names[i[0] - 1] for i in net.getUnconnectedOutLayers()]
colors = np.random.uniform(0, 255, size=(len(classes), 3))
# Loading image

# Detecting objects
blob = cv2.dnn.blobFromImage(img, 0.00392, (416, 416), (0, 0, 0), True, crop=False)
net.setInput(blob)
