Yes, the source files are not included in the distributions. So that’s normal. Just download / clone the repo and point that for VS.
Thanks!
I included the repo in directory by going to the project properties, but here are the errors I get. Any idea why?

This error appears when using Microsoft Visual Studio 2019 x64 instead of Ninja.
When trying Ninja, the error is same. It says it can not find c:\w\1\s\windows\pytorch\torch\csrc\api\src\data\datasets\mnist.cpp. Is there anything wrong with the initials of the path: c:\w\1\s\windows\? This path doesn’t exist, right?
Oh! Finally done. Looks like there was a problem with path to the source repo of PyTorch.
Thanks @peterjc123 for your patience! 
I’m having the same problems. What were the exact steps you took to fix this.
I have both the repo and the libtorch downloaded but I’m not sure how to point one to the other.
Thanks,
dave
