Are you sure you posted to the right project. I don't find anything called colorize.lua here.

I have downloaded all the file and as well as ImageNet model when
Usage is:
th colorize.lua <input_image> <output_image> colornet_imagenet.t7
and i got this errors

But this is not siggraph2016_colorization, this is neural_style.
