Libtorch operator/syntax errors in Visual Studio

C++
1

Hi recently I’ve installed Libtorch and I was able to use it in my new Visual Studio project without a problem. Currently I am trying to use Libtorch in an existing CUDA project. But I am having these strange errors when I include torch header and I couldn’t find any solution in the internet regarding to my problem. Does anyone have any idea what might be the cause of these errors?

My environment:
Windows 10
CUDA 10.1
Visual Studio 2017

There was a macro in another library which has same name as a typename in Libtorch library(which was a macro called V in my case), that’s why it was confused in compilation.
