Check failed: registry.count(type) == 1 (0 vs. 1) Unknown layer type: DeformableConvolution

I added cpp cu hpp and proto definition to my caffe, compile is ok. But when I ran the MNIST example, I got this error.

Ok, I have solved this problem. In the deformable_conv_layer.cpp: change

#ifdef CPU_ONLY
STUB_GPU(DeformableConvolutionLayer);
#endif
INSTANTIATE_CLASS(DeformableConvolutionLayer);
}  // namespace caffe

to

#ifdef CPU_ONLY
STUB_GPU(DeformableConvolutionLayer);
#endif
INSTANTIATE_CLASS(DeformableConvolutionLayer);
REGISTER_LAYER_CLASS(DeformableConvolution); // add register
}  // namespace caffe

this will work in old caffe version.

Sorry， I don't remember the version of caffe. But I didn't use cmake .., just make all test runtest.

thanks，I solved the same problem; the version of caffe is caffe-window
