Failed to run MSBuild.exe - caffe

Question

I am trying to install CAFFE for Python 3.5 in windows 10. I follow the instructions in https://github.com/BVLC/caffe/tree/windows, and set With_Ninja=0; I get the following error when executing "scripts\build_win.cmd" in command prompt. (I am running visual studio 15 2017)
c:\projects\caffe>scripts\build_win.cmd

Answer 1

your version of VS doesn't match with the required version. See:
I am running visual studio 15 2017
and,
INFO: CMAKE_GENERATOR = "Visual Studio 14 2015 Win64"
Now, you should change your version to VS 15 but as I recall VS 15 won't support "caffe" and/or will be buggy. Therefore, you should get VS 14 (Visual Studio 2015).
In fact, you don't even need to install the whole thing, install MSBuild.exe (a.k.a Build Tools) for 2015 version, add the path of .exe to system variables if it's not done automatically. The path should probably be C:\Program Files (x86)\MSBuild\14.0\Bin and that should be enough to fix the issue.
P.S. Additionally, change
INFO: PYTHON_VERSION = 2
to,
INFO: PYTHON_VERSION = 3
because you are using Python 3.5
P.P.S. If you didn't follow the instructions for GPU support, you're gonna need to go back and do or change
INFO: CPU_ONLY = 0
to,
INFO: CPU_ONLY = 1
Good luck.
