TypeError: create_int(): incompatible function arguments

Question

I've Been Recently Learning Computer Vision using python, and when making a hand detector project, I encountered this error :-

Traceback (most recent call last):

And I tried Very Much Debugging it, But Not Successfull :(, So Please Help me, Here's The Code That I've Written:-

import cv2
import mediapipe as mp
import time

class handDetector():
    def __init__(self, mode=False, maxHands = 2, detectionCon=0.5, trackCon = 0.5):
        self.mode = mode
        self.maxHands = maxHands
        self.detectionCon = detectionCon
        self.trackCon = trackCon

        self.mpHands = mp.solutions.hands
        self.hands = self.mpHands.Hands(self.mode, self.maxHands, self.detectionCon, 
                                        self.trackCon)
        self.mpDraw = mp.solutions.drawing_utils

def findHands(self, img, draw=True):
    imgRGB = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
    results = self.hands.process(imgRGB)
    # print(results.multi_hand_landmarks)

    if results.multi_hand_landmarks:
        for handLms in results.multi_hand_landmarks:
            if draw:
                self.mpDraw.draw_landmarks(img, handLms, self.mpHands.HAND_CONNECTIONS)
    return img

            # for id, lm in enumerate(handLms.landmark):
            #     # print(id, lm)
            #     h, w, c = img.shape
            #     cx, cy = int(lm.x*w), int(lm.y*h)
            #     print(id, cx, cy)
            #     # if id == 4:
            #     cv2.circle(img, (cx, cy), 15, (255,0,255), cv2.FILLED)



def main():
    pTime = 0
    cTime = 0
    cap = cv2.VideoCapture(0)
    detector = handDetector()

while True:
    success, img = cap.read()
    img = detector.findHands(img)
    
    cTime = time.time()
    fps = 1/(cTime-pTime)
    pTime = cTime

    cv2.putText(img, str(int(fps)),(10, 70), cv2.FONT_HERSHEY_COMPLEX, 3, (255,0,255),3)

    cv2.imshow("Image", img)
    cv2.waitKey(1)








if __name__ == "__main__":
    main()

I've Tried Making A Class of Hand Detector, Which Does the same thing to detect hand but we can also use it in our other files, That's why I've written this code, and encountered this issue!

Answer 1

In the def __init__(), at the code:

self.hands = self.mpHands.Hands(self.mode, self.maxHands, self.detectionCon, self.trackCon)

try adding model complexity for the third parameter in the Hands() as below:

self.hands = self.mpHands.Hands(self.mode, self.maxHands, self.modelComplex, self.detectionCon, self.trackCon)

So a total of five parameters in the self.mpHands.Hands()

Here is my full code that works for me:

class handDetector():
    def __init__(self, mode=False, maxHands=1, modelComplexity=1, detectionCon=0.5, trackCon=0.5):
        self.mode = mode
        self.maxHands = maxHands
        self.modelComplex = modelComplexity
        self.detectionCon = detectionCon
        self.trackCon = trackCon

        self.mpHands = mp.solutions.hands
        self.hands = self.mpHands.Hands(self.mode, self.maxHands, self.modelComplex, 
                                        self.detectionCon, self.trackCon)
