Dear Sir, Thanks for your effort on this repo. I have met some problem.Could please help ? OS: Windows 10 VS2019 I have compile detectron2 project as a statci lib successfully. But while I use the Detectron2.lib on another console project, it give error.The error imformations below:

Why the cuda function didn't compile?

Look forward your reply！

I have solved it. The problem is that i haven't compile the NetLib2.lib. And I found the rederence time is a litle long.It takes about 6 second on the forward time.

@BigPandaCPU Hi,

Did you run it on Windows 10 successfully? I used TorchScript but it did not run on Windows 10.
