TypeError: tuple indices must be integers or slices, not str, when using MTCNN

Question

当我想访问以下元组时出现以下错误

[{'box': [215, 102, 179, 238], 'confidence': 0.999460756778717, 'keypoints': {'left_eye': (277, 193), 'mouth_left': (287, 284), 'mouth_right': (356, 283), 'nose': (330, 239), 'right_eye': (361, 191)}}]

for person in face_locations:
bounding_box = person['box']   #in this line I get the error
keypoints = person['keypoints']



cv2.rectangle(img_final,
              (bounding_box[0], bounding_box[1]),
              (bounding_box[0]+bounding_box[2], bounding_box[1] + bounding_box[3]),
              (0,155,255),
              2)
cv2.circle(img_final,(keypoints['left_eye']), 2, (0,155,255), 2)
cv2.circle(img_final,(keypoints['right_eye']), 2, (0,155,255), 2)
cv2.circle(img_final,(keypoints['nose']), 2, (0,155,255), 2)
cv2.circle(img_final,(keypoints['mouth_left']), 2, (0,155,255), 2)
cv2.circle(img_final,(keypoints['mouth_right']), 2, (0,155,255), 2)

Answer 1

而不是这个：

for person in face_locations:
bounding_box = person['box']   
keypoints = person['keypoints']

你应该这样做：

person = face_locations[0]
bounding_box = person['box']
keypoints = person['keypoints']
print(bounding_box, keypoints)

结果：

 [`215, 102, 179, 238]`

{'left_eye': (277, 193), 'mouth_left': (287, 284), 'mouth_right': (356, 283), 'nose': (330, 239), 'right_eye': (361, 191)}
