Some questions about your code

[vtddggg]

Thank you for sharing!!

I found that you get color_image through bluring : batch_colors = np.array([self.imageblur(ba,True) for ba in batch]) / 255.0

Bluring is a good way to get color prior when we have groundtruth images. But if I only have a line map (without groundtruth), bluring can not work because bluring a line image can not get any color informations. As your paper said, a color_predict network can predict the color from a line image. I think it is a very nice idea while I found main.py does not realize this part of functions. Maybe you have tried in guess_color.py.

Good job!!
