报错：OpenCV打不开文件

打不开相关文件
AttributeError: module 'cv2.cv2' has no attribute 'Sobe1'
有分析贴说是opencv-python、opencv-contrib-python版本问题
重新下载安装同一版本后依然无法运行

以下是源代码

#coding: utf-8
#sample5-3.py

import cv2


try:
    img = cv2.imread(r'C:\Users\www09\Desktop\LIYIAKNG1\sample06.png', cv2.IMREAD_GRAYSCALE)
    if img is None:
        raise FileNotFoundError('ファイルが見つかりません')

    cv2.imshow('sample01', img)

    ret, th = cv2.threshold(img, 127, 255, cv2.THRESH_BINARY)
    cv2.imshow('sample02', th)

    ada1 = cv2.adaptiveThreshold(img, 255, cv2.ADAPTIVE_THRESH_MEAN_C, cv2.THRESH_BINARY, 11, 2)
    cv2.imshow('sampleo03', ada1)

    ada2 = cv2.adaptiveThreshold(img, 255, cv2.ADAPTIVE_THRESH_GAUSSIAN_C, cv2.THRESH_BINARY, 11, 2)
    cv2.imshow('sampleo04', ada2)







    cv2.waitKey(0)
    cv2.destroyAllwindows()

except FileNotFoundError as e:
    print(e)
