Getting Caffe installed

[Ian Ono]

Hi,

I'm trying to install Caffe (CPU only) on windows 7 platform following https://github.com/BVLC/caffe/tree/windows.  I have CMake and Visual Studio 2017 installed.  When I run the build_win.cmd I get the following errors:
The system cannot find the path specified.
CMake Error: CMake was unable to find a build program corresponding to "Ninja". CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.
CMake Error:  CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error:  CMAKE_CXX_COMPILER not set, after EnableLanguage
ERROR:  Configure failed

So which path needs to be set (or how can I find out which path)
What is Ninja?  Do I really need it?  If not how do I get around it.
How do I set my compilers (or is that a path problem)?

Hi Ian,
I am having similar problems - trying to install Caffe.
I think however you need to use Visual Studio 2015 and not 2017. You will see the prebuilt binaries are only for python 3.5 and visual studio 2015 - but i could be wrong.

re. ninja,
maybe first try to set WITH_NINJA=0 in build_win.cmd - this will prevent Ninja from being used - see below.

Using the Ninja generator

You can choose to use the Ninja generator instead of Visual Studio for faster builds. To do so, change the option set WITH_NINJA=1 in the build_win.cmd script. To install Ninja you can download the executable from github or install it via conda:

Hi,

I thought I read some where that Visual Studio 2017 is only a problem if you want to run CUDA with it.  I had thought by running CPU only I could get around that.  Anyhow I am trying to get my hands on a copy of VS 2015.

Thanks for your help.  I hope your problems gets solved.
