The code I wrote with hand tracking module and mediapipe gives an error

Question

I was making the sound off/on video when I closed my hand, but I got an error in the first code, what is the reason?

I get the following error:

raceback (most recent call last):
  File "c:\Users\yegen\Desktop\ses denemeeeeee\sesdeneme2.py", line 15, in <module>    
    detector = htm.handDetector(detectionCon=0.5)

And this is my code:

import cv2
import time
import numpy as np 
import handtrackingmodule as htm
import math


###############################
wCam, hCam = 640, 480
###############################
cap = cv2.VideoCapture(0)
cap.set(3, wCam)
cap.set(4, hCam)

detector = htm.handDetector(detectionCon=0.5)

while True:
    success, img = cap.read()
    img = detector.findHands(img)
    
    cv2.imshow("İmg", img)
    cv2.waitKey(1)

Answer 1

Try this

import cv2
import time
import numpy as np 
import handtrackingmodule as htm
import math


###############################
wCam, hCam = 640, 480
###############################
cap = cv2.VideoCapture(0,cv2.CAP_DSHOW)
cap.set(3, wCam)
cap.set(4, hCam)

detector = htm.handDetector(detectionCon=0.5)

while True:
    success, img = cap.read()
    img = detector.findHands(img)
    
    cv2.imshow("İmg", img)
    cv2.waitKey(1)

cv2.destroyAllWindows()
