For the first warning, we have, out = "aten/src/Aten/Conf.h" at line 533
we have ":aten_src_ATen_config", at line 595
is this where causing the duplication to occur?

This is my first time joining an open source project as a student, will be appreciated if you could give some hints on it.

aten_src_ATen_config is probably the legitimate rule, and its the other rule that's causing the problem. Maybe try putting an exclude on the glob in aten_headers.
