使用手势的虚拟鼠标

Question

# Imports

import cv2
import mediapipe as mp
import pyautogui
import math
from enum import IntEnum
from ctypes import cast, POINTER
from comtypes import CLSCTX_ALL
from pycaw.pycaw import AudioUtilities, IAudioEndpointVolume
from google.protobuf.json_format import MessageToDict
import screen_brightness_control as sbcontrol

pyautogui.FAILSAFE = False
mp_drawing = mp.solutions.drawing_utils
mp_hands = mp.solutions.hands
smoothing = 10

在虚拟鼠标代码中，除亮度控制和音量控制外，一切正常，代码中没有错误，任何人都可以帮助我修复它。当我运行这段代码时，捏合手势没有执行。
