@zhaoweicai detectiondatalayer is unkown layer ,我编译的时候看到它编译detection_data_layer.cpp,当我在layer_factory.cpp加入INSTANTIATE_CLASS(DetectionDataLayer); REGISTER_LAYER_CLASS(DetectionData);,编译的时候再次报错CXX/LD -o .build_release/tools/upgrade_net_proto_text.bin .build_release/lib/libcaffe.so: undefined reference to caffe::DetectionDataLayer<double>::ShuffleMixAspectGroupList()' .build_release/lib/libcaffe.so: undefined reference to caffe::DetectionDataLayer<float>::ShuffleList()' .build_release/lib/libcaffe.so: undefined reference to caffe::DetectionDataLayer<double>::~DetectionDataLayer()' .build_release/lib/libcaffe.so: undefined reference to caffe::DetectionDataLayer<double>::PrefetchRand()'请问是什么原因呢?是opencv的版本吗??

This layer requires OpenCV. Have you turned off OpenCV?
