python - python中opencv的imread（）不适用于任何图像

Question

我正在尝试使用 opencv 的 imread() 函数读取图像，从而尝试显示我阅读的内容。但它无法读取任何内容。

import cv
import sys

# Get user supplied values
imagePath = sys.argv[1]
cascPath = sys.argv[2]

# Create the haar cascade
faceCascade = cv2.CascadeClassifier(cascPath)

# Read the image
image = cv2.imread(imagePath)
cv2.imshow("Image read", image)

那是我在 python 中的代码，我正在使用命令提示符执行，因此：

C:\> C:\Python27\python.exe C:\Users\Divy\Desktop\FaceDetectmaster\face_detect.py C:\\Users\\Divy\\Deskop\\FaceDetect-master\\abba.png C:\\Users\\Divy\\Desktop\
\FaceDetect-master\\haarcascade_frontalface_default.xml
