Compilation error

Hey I am impressed by your results and want to try your edge detection code. I am getting this error while doing make all for hed. No error when i install original Caffe.

I am facing the same problem, so can you tell me please how did you solve it ?

[ShubhamAgarwal12]

Since my PC do not have any GPU, I commented the line that was throwing the error. It then worked fine.

[samouha]

Which line do you mean please ?

[ShubhamAgarwal12]

STUB_GPU_BACKWARD(SigmoidCrossEntropyLossLayer, Backward);

in "src/caffe/layers/sigmoid_cross_entropy_loss_layer.cpp".

I'm using caffe in cpu only mode. when i do make all in hed-master, it is throwing up the following error.

src/caffe/layers/sigmoid_cross_entropy_loss_layer.cpp:120:1: error: no ‘void caffe::SigmoidCrossEntropyLossLayer::Backward_gpu(const std::vector<caffe::Blob>&, const std::vector&, const std::vector<caffe::Blob>&)’ member function declared in class ‘caffe::SigmoidCrossEntropyLossLayer’
Makefile:518: recipe for target '.build_debug/src/caffe/layers/sigmoid_cross_entropy_loss_layer.o' failed
make: *** [.build_debug/src/caffe/layers/sigmoid_cross_entropy_loss_layer.o] Error 1
Any help is appreciated

In src/caffe/layers/sigmoid_cross_entropy_loss_layer.cpp try removing lines:

#ifdef CPU_ONLY STUB_GPU_BACKWARD(SigmoidCrossEntropyWeightedLossLayer, Backward); #endif

it may helps.
