I tried to run the below mentioned Example code. but I got an Attribute error saying

AttributeError: module ‘cvzone’ has no attribute ‘HandDetector’.

Help me to resolve this issue.

the Example code is.

import cvzone
import cv2

cap = cv2.VideoCapture(0)
cap.set(3, 1280)
cap.set(4, 720)
detector = cvzone.HandDetector(detectionCon=0.5, maxHands=1)

while True:
    # Get image frame
    success, img = cap.read()

    # Find the hand and its landmarks
    img = detector.findHands(img)
    lmList, bbox = detector.findPosition(img)
    
    # Display
    cv2.imshow("Image", img)
    cv2.waitKey(1)

Hey its-Yogesh, what francoisschwarxentruber said is right. Try this:

from cvzone.HandTrackingModule import HandDetector import cv2

cap = cv2.VideoCapture(0) detector = HandDetector(detectionCon=0.8, maxHands=2) while True: # Get image frame success, img = cap.read() # Find the hand and its landmarks hands, img = detector.findHands(img) # with draw #hands = detector.findHands(img, draw=False) # without draw

if hands:
    # Hand 1
    hand1 = hands[0]
    lmList1 = hand1["lmList"]  # List of 21 Landmark points
    bbox1 = hand1["bbox"]  # Bounding box info x,y,w,h
    centerPoint1 = hand1['center']  # center of the hand cx,cy
    handType1 = hand1["type"]  # Handtype Left or Right

    fingers1 = detector.fingersUp(hand1)

    if len(hands) == 2:
        # Hand 2
        hand2 = hands[1]
        lmList2 = hand2["lmList"]  # List of 21 Landmark points
        bbox2 = hand2["bbox"]  # Bounding box info x,y,w,h
        centerPoint2 = hand2['center']  # center of the hand cx,cy
        handType2 = hand2["type"]  # Hand Type "Left" or "Right"

        fingers2 = detector.fingersUp(hand2)

        # Find Distance between two Landmarks. Could be same hand or different hands
        length, info, img = detector.findDistance(lmList1[8], lmList2[8], img)  # with draw
        # length, info = detector.findDistance(lmList1[8], lmList2[8])  # with draw
# Display
cv2.imshow("Image", img)
if cv2.waitKey(1) == ord('q'):
    break

cap.release() cv2.destroyAllWindows()

i can´t get the distance between 2 landmarks to show, any help?

from cvzone.HandTrackingModule import HandDetector import cv2

cap = cv2.VideoCapture(0) detector = HandDetector(detectionCon=0.5, maxHands= 1)

while True:

#hacer un cuadro success, img = cap.read()

#detectar las manos y trazar las rayitas hands, img = detector.findHands(img) # with draw

if hands:
    # Mano 1
    hand1 = hands[0]
    lmList1 = hand1["lmList"]  # List of 21 Landmark points
    bbox1 = hand1["bbox"]  # Bounding box info x,y,w,h
    centerPoint1 = hand1['center']  # center of the hand cx,cy
    handType1 = hand1["type"]  # Handtype Left or Right

    fingers1 = detector.fingersUp(hand1)

if len(hands) == 2:
    # Mano 2
    hand2 = hands[1]
    lmList2 = hand2["lmList"]  # List of 21 Landmark points
    bbox2 = hand2["bbox"]  # Bounding box info x,y,w,h
    centerPoint2 = hand2['center']  # center of the hand cx,cy
    handType2 = hand2["type"]  # Hand Type "Left" or "Right"

    fingers2 = detector.fingersUp(hand2)

    # Distancia entre 2 Landmarks. puede ser de la misma mano OJOOOOOO
    length, info, img = detector.findDistance(lmList2[4], lmList2[12], img)  # with draw
        # length, info = detector.findDistance(lmList1[8], lmList2[8])  # with draw

# Display
cv2.imshow("Image", img)
if cv2.waitKey(1) == ord('q'):
    break

cap.release() cv2.destroyAllWindows()
