Maybe this is a potential bug.

img = xm.io.img.load(path)
img = img[:, :, :3] # discards alpha
hw = img.shape[:2]
#############################
The pred_lvis.png has no third channel similar to grey image.
So, it should be changed to this as follows:
#############################
Img = xm.io.img.load(path
if len(img.shape) == 2:
stacked_img = np.stack((img,)*3, axis=-1)
img = stacked_img
img = img[:, :, :3] # discards alpha
hw = img.shape[:2]

Thank you for the suggestion. Although I don't recall encountering this problem, it won't hurt to adopt this change you proposed. Incorporated this in f50a06c.
