Build from source (Windows OS, Anaconda environment)

Can someone please point me to a step-by-step guide for building Pytorch from source in Windows OS and
the Anaconda environment? All the guides I’m finding are either out of date or not clear enough for me to understand. Thanks.

Edit: I should mention that I have already successfully installed Pytorch via the conda route, but I need to have the most up to date (unreleased) version of Pytorch so I wish to build from source.

Could you please check -

I followed the steps in the guide, but my build ultimately failed with the following errors:

c:\users\wagne134\anaconda3\include\pyconfig.h(59): fatal error C1083: Cannot open include file: ‘io.h’: No such file or directory
error: command ‘C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\VC\Tools\MSVC\14.11.25503\bin\HostX64\x64\cl.exe’ failed with exit status 2

Could you give me the result of the following command?

echo %INCLUDE%
echo %LIB%

I’m afraid that you didn’t install the MSVC 14.11 toolset.
