Is it "light" version? I've noticied it uses less memory than original implementation, thus wondering.

In the original repository https://github.com/taki0112/UGATIT
there is remark at almost bottom of page:
"If the memory of gpu is not sufficient, set --light to True
But it may not perform well
paper version is --light to False
"
So I am wondering which version is implemented in there, light or not?
It uses as much memory as light version; I hope it is not "light".
