Use linux based pytorch model in windows c++ code

C++
1

I am looking forward to the best way to use my linux based pytorch model to the c++ program in windows.
Can someone please guide me to the best options?

You can follow the export to C++ tutorial, the export format is the same on Windows and Linux, so you can make the step Python on Linux to C++ on Windows.

Best regards

Thanks, I tried following the tutorial as it is but i am facing issues in building the application via cmake.

This is my error report:

So here I must admit that I know next to zero about building things for windows, but if you have the 2010 build tools installed (have you?), you might need to include them into the PATH.
To me, this seems to be something around how to build general things on Windows more than PyTorch specific.
