为什么读取不出来图片呢

import cv2 as cv
import matplotlib.pyplot as plt
import numpy as np
%matplotlib inline

img = cv2.imread("‪‪‪C:/Users/86153/Desktop/cat.jpg")
cv2.imshow ("image",img)
cv2.waitKey(0)
cv2.destroyAllWindows()

error: OpenCV(3.4.13) C:\Users\appveyor\AppData\Local\Temp\1\pip-req-build-08sz0kb3\opencv\modules\highgui\src\window.cpp:382: error: (-215:Assertion failed) size.width>0 && size.height>0 in function 'cv::imshow'

img 是否为空？路径不对？
