I’ve been working on hand gesture controlled led brightness on Arduino. And i get this error in python code.

TypeError: create_int(): incompatible function arguments. The following argument types are supported:
    1. (arg0: int) -> mediapipe.python._framework_bindings.packet.Packet

Invoked with: 0.8

and this is the code that i wrote

import serial
import cvzone
import math
import cv2
from cvzone.HandTrackingModule import HandDetector
serialcomm = serial.Serial('COM7', 9600)
serialcomm.timeout = 1
cap=cv2.VideoCapture(0) 
detector = HandDetector(detectionCon=0.8, maxHands=1)
l=[]
while True:
    success,img =cap.read()
    img=cv2.resize(img,(500, 500))
    img=detector.findHands(img)
    l,box = detector.findPosition(img,draw=False)
    if l:
        #f=detector.fingersUp()
        x1=l[4][0]
        y1=l[4][1]
        x2=l[8][0]
        y2=l[8][1]
        cv2.circle(img,(x1,y1),7,(0,255,255),1)
        cv2.circle(img,(x2,y2),7,(0,255,255),1)
        cv2.line(img,(x1,y1),(x2,y2),(0,255,0),2)
        d=int(math.sqrt(math.pow(x2 - x1, 2)+math.pow(y2 - y1, 2) * 1.0))
        d=int((d/110)*255)
        e='n'
        if 0<d<256:
            cv2.putText(img,str(d),(20,30),cv2.FONT_HERSHEY_COMPLEX,.7,(255,255,255),1)     
            serialcomm.write(str(d).encode())
            serialcomm.write(e.encode())
                     
    cv2.imshow('Image',img)  
    if cv2.waitKey(20) & 0xFF == 27:
        break        
cv2.destroyAllWindows()

and there is full error
