Importazione di errore:caricare una DLL non riuscita:Il modulo specifico potrebbe non essere trovato

Sto cercando di eseguire handtracking programma del modulo,ma ottengo questo errore dll durante il tentativo di importare handtracking modulo

Il codice del programma:

import cv2

from cvzone.HandTrackingModule import HandDetector

detector=HandDetector(detectionCon=0.8)

cap =cv2.VideoCapture(0)

cap.set(3,1080)

cap.set(4,720)

while True:
    
   sucess,img=cap.read()
   img=detector.findHands(img) 
         
   lmlist,bboxinfo=detector.findPosition(img)
   
   cv2.imshow('video',img)
   
   cv2.waitKey(1)

Errore che ricevo:
