Answer 1

This error means that you are loading an empty image. As specified in the error, the image must have a width > 0 and a height > 0.

Here, I was able to open an image with exactly the same code.

Possible causes of error:

• The image does not exist in the directory. Vale checks again and try something like: cv2.imread("C:\\path\\to\\image.png") or cv2.imread("C:/path/to/image.png"));

• The image extension may be wrong. Remember, .jpg is other than .jpeg

• You may not have direct access to the image folder.
