无法在Mac上使用OpenCV打开图像

Question

I am trying to open an image with OpenCV on mac with Python with this simple program:

import numpy as np
import cv2
img = cv2.imread("image.jpg", 1)
cv2.imshow("image", img)
cv2.waitKey(0)
cv2.destroyAllWindows()

But every time I run it I get this error:

   cv2.imshow("image", img)
   error: /Users/travis/build/skvark/opencv-
   python/opencv/modules/highgui/src/window.cpp:325: error: (-215) 
   size.width>0 && size.height>0 in function imshow

I have researched this question but it says that the image may be empty, but I'm pretty sure my image isn't empty as I can open it and look at it.

Answer 1

I have faced same problem couple of days and I solved my problem by giving full path of image in cv2.imread()

here's a sample

import cv2
import os

img = cv2.imread(os.path.expanduser( "~/Downloads/Pics/A.jpg"))
cv2.namedWindow("Images")
cv2.imshow('Images',img)
cv2.waitKey(1)
cv2.destroyAllWindows()
