python - Mediapipe 的“multi_hand_landmarks”不起作用

Question

我第一次尝试opencv和handtracking。我正在按照“Mediapipe”官方网站上的逐步代码进行操作。但是每当我尝试编写“results.multi_hand_landmarks”时，PyCharm 都会给出错误提示Unresolved Attribute Reference "multi_hand_landmarks" for class "NamedTuple"

你能帮帮我吗？

Answer 1

import mediapipe
import cv2
import null as null

drawingModule = mediapipe.solutions.drawing_utils
handsModule = mediapipe.solutions.hands

capture = cv2.VideoCapture(0)

with handsModule.Hands(static_image_mode=False, min_detection_confidence=0.7, min_tracking_confidence=0.7,max_num_hands=2) as hands:
        while (True):
            ret, frame = capture.read()
            results = hands.process(cv2.cvtColor(frame, cv2.COLOR_BGR2RGB))
            if results.multi_hand_landmarks:
                for handLandmarks in results.multi_hand_landmarks:
                    drawingModule.draw_landmarks(frame, handLandmarks, handsModule.HAND_CONNECTIONS)
            cv2.imshow('Test hand', frame)
            if cv2.waitKey(1) == 27:
                break
cv2.destroyAllWindows()
capture.release() here

当将鼠标悬停在与您相同的行上但代码运行时，此代码也会显示相同的错误。可能是 PyCharm 和 Mediapipe 库的错误。

在源代码中它在那里：

输出=['multi_hand_landmarks', 'multi_handedness'])
