environment:

OS: win 10

IDE: Visual Studio 2013

opencv: 3.1 master from https://github.com/Itseez/opencv

opencv_contrib: from https://github.com/Itseez/opencv_contrib

graphic card: nvidia GeForce 610M

CUDA: tool kit v7.5 & cudnn is install

what I have done:

  1. build the dll & lib by http://docs.opencv.org/3.1.0/de/d25/tutorial_dnn_build.html and success

  2. use the sample code (from http://docs.opencv.org/3.1.0/d5/de7/tutorial_dnn_googlenet.html)with the caffe model & prototxt (download in current folder) and build success

Question: once I run my code. it will fail during import caffe model file

please point me out what wrong, thanks a lot....

the error is bellow:

[libprotobuf ERROR D:\openCV_root\opencv_contrib\modules\dnn\3rdparty\protobuf\src\google\protobuf\text_format.cc:245] Error parsing text-format caffe.NetParameter: 6:15: Message type "caffe.LayerParameter" has no field named "input_param".

OpenCV Error: Unspecified error (FAILED: ReadProtoFromTextFile(param_file, param).Failed to parse NetParameter file: ./bvlc_googlenet.prototxt) in cv::dnn::ReadNetParamsFromTextFileOrDie, file D:\openCV_root\opencv_contrib\modules\dnn\src\caffe\caffe_io.cpp, line 1101

I fine the root cause from " github.com/BVLC/caffe/issues/3846 " I should change to "old definition" after fix this, I will fail at " net.forward(); " the error msg is below: OpenCV Error: Assertion failed (input.dims() == 4 && (input.type() == CV_32F || input.type() == CV_64F)) in cv::dnn::ConvolutionLayerImpl::allocate, file D:\openCV_root\opencv_contrib\modules\dnn\src\layers\convolution_layer.cpp, line 89 - Chi-Fang Hsieh

build opencv and opencv_contrib with the tag 3.1.0 works for opencv dnn

The DNN importer doesn't support some constructs of the caffe prototxt file. Nevertheless, you can modify and use it.

Link to issue on github.
Link to modified prototxt.
