i'm using mask image as gray scale. is there any idea to change input mask as grayscale?

[DLbeginner]

the original code is for rgb mask images.

but i'm using grayscale mask images as grayscale.

do i need to convert mask image or read images as grayscale?

You should be able to follow the n_classes == 1 code path where masks have one channel in [0, 1]
