#print(img1.shape)
#print(img2.shape)#convert unit8 to int numbers, then subtract, then 2D to 1D array
#subArr = np.subtract(img1[:, :, 0].tolist(), img2.tolist()).flatten()intersection = np.sum(np.logical_and(img1, img2[:, :, 0]))
union = np.sum(np.logical_or(img1, img2[:, :, 0]))#Intersection over Union
iou_score = intersection / unionprint(iou_score)

报错：

Img1 should be the .jpg file that has 3 channels

If your image is 2D, just delete one of the ,: from the code

Or just delete the [:,:,0]

If it's 2D, just img1, if it's 3D img1[:, :, 0]
