Mediapipe 手 python 结果没有 multi_hand_world_landmarks

Question

我尝试在 Python 中使用 MediaPipe。

它工作正常，但hands.process() 的结果有multi_hand_world_landmarks，并且没有multi_hand_world_landmarks，我得到了

AttributeError: type object 'SolutionOutputs' has no attribute 'multi_hand_world_landmarks' 

为什么？

源中的注释 https://github.com/google/mediapipe/blob/master/mediapipe/python/solutions/hands.py 表示结果必须有这个属性：

Returns:
  A NamedTuple object with the following fields:
    1) a "multi_hand_landmarks" field that contains the hand landmarks on
       each detected hand.
    2) a "multi_hand_world_landmarks" field that contains the hand landmarks
       on each detected hand in real-world 3D coordinates that are in meters
       with the origin at the hand's approximate geometric center.
    3) a "multi_handedness" field that contains the handedness (left v.s.
       right hand) of the detected hand.

它可能只出现在具有特殊背景的图片中吗？

您好，我遇到了同样的问题，然后我检查了本地文件中的 hands.py。我发现输出定义中没有“multi_hand_world_landmarks”。我正在尝试更新到最新的媒体管道来解决它。
