Hi all, I'm on ubuntu17.04 and I installed caffe-cuda. This package simplifies the installation of caffe, which is cool! But when I start to use caffe, I received "unknown engine" error message. F0816 16:03:41.772136 15446 layer_factory.cpp:69] Layer conv0 has unknown engine. *** Check failure stack trace: *** @ 0x7ff4d11585ad google::LogMessage::Fail() @ 0x7ff4d115a413 google::LogMessage::SendToLog() @ 0x7ff4d115813b google::LogMessage::Flush() @ 0x7ff4d115adfe google::LogMessageFatal::~LogMessageFatal() @ 0x7ff4d16981b1 caffe::GetConvolutionLayer<>() @ 0x7ff4d1707daf caffe::LayerRegistry<>::CreateLayer() @ 0x7ff4d1724655 caffe::Net<>::Init() @ 0x7ff4d17239de caffe::Net<>::Net() @ 0x7ff4d173d68f caffe::Solver<>::InitTrainNet() @ 0x7ff4d173ccc6 caffe::Solver<>::Init() @ 0x7ff4d173c949 caffe::Solver<>::Solver() @ 0x7ff4d1747913 caffe::SGDSolver<>::SGDSolver() @ 0x7ff4d174cadf caffe::Creator_AdamSolver<>() @ 0x556fd90de00a caffe::SolverRegistry<>::CreateSolver() @ 0x556fd90dae4b train() @ 0x556fd90dd8a9 main @ 0x7ff4cf6503f1 __libc_start_main @ 0x556fd90d99da _start @ (nil) (unknown) If I turn off the switch "engine: CUDNN" in prototxt file, caffe works perfectly..... I mean, it still use cuda, just not cudnn libraries.... Then I checked the CUDNN installation. (the existence of libcudnn files and cudnn.h) They are well placed in /usr/local/include and /usr/local/lib, which can not be missed anyway. Now as caffe is installed with apt, I have little knowledge about the links and configurations. I cannot even find the Makefile.config...... So why is cudnn not found?? How can I configure the caffe installed by apt system?? Best regards, Xin
