CPU Only build

[Sky6596]

Hi, can you give me the instructions to build CPU only, I don't have GPU. I changed CpuOnlyBuild to True and UseCuDNN to False but when I build libcaffe in VS2015, I meet some errors like that:

Severity Code Description Project File Line Suppression State Error C2333 'caffe::ProposalLayer::Backward_gpu': error in function declaration; skipping function body (compiling source file ....\src\caffe\layers\proposal_layer.cpp) libcaffe D:\Caffe\caffe-windows\include\caffe\layers\proposal_layer.hpp 36
Severity Code Description Project File Line Suppression State Error C2333 'caffe::ProposalLayer::Backward_gpu': error in function declaration; skipping function body (compiling source file ....\src\caffe\layers\proposal_layer.cpp) libcaffe D:\Caffe\caffe-windows\include\caffe\layers\proposal_layer.hpp 36
Severity Code Description Project File Line Suppression State Error C3861 'caffe_gpu_div': identifier not found libcaffe D:\Caffe\caffe-windows\src\caffe\layers\batch_norm_layer.cpp 203

And when I build project caffe:

Severity Code Description Project File Line Suppression State Error C1083 Cannot open include file: 'pyconfig.h': No such file or directory caffe D:\Caffe\caffe-windows\windows\thirdparty\Boost\boost\python\detail\wrap_python.hpp 50

I fixed some bugs in the CPU_ONLY mode. Can you pull the latest version and try again?

I'm sorry but it still has some errors:

I use VS 2015, Anaconda2, I copied full thirdparty to windows/thirdparty, changed CpuOnlyBuild to True, UseCuDNN to false, link to MATLAB, Anaconda2. But when I build it shows errors like that. Can you continue fixing it ?

[happynear]

NCCL is a library for multi-GPU processing. You should set USE_NCCL to false if you are using CPU_ONLY mode.

[happynear]

Because NCCL is newly added, the document wasn't updated.

[Sky6596]

Sorry, I changed UseNCCL to false but I still have some errors:

I hope you can help me :(

[Sky6596]

Additionally, I changed "(CudaVersion)8.0(/CudaVersion)" to "(CudaVersion)(/CudaVersion)", removed link from "(CuDnnPath)(/CuDnnPath)", but it hasn't built successfully yet

[happynear]

I forgot to rename CommonSettings.props to CommonSettings.props.example when I submit the last modification. You may use the new CommonSettings.props.example and try again.

[happynear]

Please pull the lastest version. I tried to compile in CPU_ONLY mode by myself. Now it works.

[Sky6596]

OK, It built successfully. Thank you very much!!!

I've use the latest version. Somehow it occurs to me with the same problem at the very begining of this issue..

1>....\src\caffe\layers\infimum_loss_layer.cpp(55): error C2995: “void caffe::Layer::Forward_gpu(const std::vector<caffe::Blob,std::allocator<_Ty>> &,const std::vector<caffe::Blob,std::allocator<_Ty>> &)”: 函数模板已经定义 1>....\src\caffe\layers\infimum_loss_layer.cpp(55): error C2995: “void caffe::Layer::Backward_gpu(const std::vector<caffe::Blob,std::allocator<_Ty>> &,const std::vector<bool,std::allocator> &,const std::vector<caffe::Blob,std::allocator<_Ty>> &)”: 函数模板已经定义 1>E:\Library\caffe-windows\include\caffe/layer.hpp(343): error C2333: “caffe::Layer::Forward_gpu”: 函数声明中有错误；跳过函数体 1>E:\Library\caffe-windows\include\caffe/layer.hpp(362): error C2333: “caffe::Layer::Backward_gpu”: 函数声明中有错误；跳过函数体 1>E:\Library\caffe-windows\include\caffe/layer.hpp(343): error C2333: “caffe::Layer::Forward_gpu”: 函数声明中有错误；跳过函数体 1>E:\Library\caffe-windows\include\caffe/layer.hpp(362): error C2333: “caffe::Layer::Backward_gpu”: 函数声明中有错误；跳过函数体

[richipower]

having the same error with the latest version :(

[rb0518]

comment out the GPU_STUB code in infimum_loss_layer.cpp, i have success in CPU_ONLY

[happynear]

I tend to remove the infimum_loss_layer. Update: Removed by this commit https://github.com/happynear/caffe-windows/commit/e04a2f644ef2fb7482d8836722b766ec6a089e09 .

[TyrionChou]

the same error fatal error C1083: 无法打开源文件: “....\src\caffe\layers\fcn_data_layer.cpp”: No such file or directory

[douhaoexia]

Sorry! I have another error with the latest version in CPU_ONLY, "fatal error C1083: : “....\src\caffe\layers\fcn_data_layer.cpp”: No such file or directory". And I wonder what source files are vital and what can be removed.

[happynear]

@TyrionChou @douhaoexia , sorry I forgot to update the project file. Please try it again,

[TyrionChou]

@happynear thank you very much！

[douhaoexia]

@happynear thank you! The libcaffe and caffe have been built successful. But when I build the pycaffe , there is an error pointing to " DEFINE_BOOST_GET_POINTER(caffe::NCCL)" in "\python\caffe_caffe.cpp" . I commented out the line and no error occurred. Will what i have done affect the use of pycaffe？

[happynear]

oh, let me add a macro to prevent compiling the NCCL...
