Error making a prediction in C++

[Sebastian Sierra]

Hi, I am working doing predictions in C++ using the following code

#include <glog/logging.h>
...
#include "caffe/caffe.hpp"
  using namespace caffe;

int main(int argc, char** argv) {
  Net<float> caffe_test_net(argv[1]);

  caffe_test_net.CopyTrainedLayersFrom(argv[2]);

  float loss;

  const vector<Blob<float>*>& result =  caffe_test_net.ForwardPrefilled(&loss);

 const float* argmaxs = result[0]->cpu_data();

  for (int i = 0; i < result[0]->num(); ++i) {

   LOG(INFO) << " Image: "<< i << " class:" << argmaxs[i];

  }

return 0;
}

This was based mainly on a Github thread 499. However this was done with a previous version of Caffe and therefore I am getting the following errors while compiling with actual version in master:

/tmp/ccxqR1yE.o: In function `main':

prediction.cpp:(.text+0x64): undefined reference to `caffe::Net<float>::Net(std::string const&)'

prediction.cpp:(.text+0x2a8): undefined reference to `google::LogMessage::~LogMessage()'

collect2: error: ld returned 1 exit status

I wanted to know if there is a mistake in my syntaxis or what should I change?

Thanks in advance.

I also encounter this error. Could you tell me how to write Makefile?

Did you link caffe library and glog in compiling?

[Caffe User]

Hello. I am having the same problem with running .cpp file. 

If you figured out, could you help me? Did you make makefile for this?

Thank you! 

[ikki Chung]

Maybe you can try this steps.

c++ prediction example with caffe

The base idea is to create you code on caffe master directories.

Here us Makefile which I use to compile C++ code, which use Caffe. You have to change directories pointing to Caffe include/lib

Hello,

I am having problem compiling c++ code outside of caffe (inside the caffe main directories works fine!). I wrote my own Makefile and since that didn't seem to work, I even tried the one Bartosz provided. I keep getting these does not name a type errors (attached below). I have a feeling this has to do with the Makefile. Is there something I am supposed to be doing that I am not? Any help would be deeply appreciated.

Thanks!

Dear Caffe User, 

Hello. I am attaching my cpp file and makefile. I hope these helps!

Were you able to compile "make all" and "make test" successfully? 

Also, please make sure your bashrc file includes correct caffe version! 

 

Best Regards,

Dong Ki Kim

Hi Dong,

Thanks for sharing the files. I created my workspace outside caffe's master directory and ran a similar program. The execution stops at 'memory_data_layer->AddMatVector(imageVector,labelVector);'. The error msg I get is :

F0324 16:27:18.655103 26477 data_transformer.cpp:228] Check failed: img_height == data_mean_.height() (323 vs. 256)
*** Check failure stack trace: ***
Aborted (core dumped)

I am a new caffe and learning CNN. If you understand the error, I'd greatly appreciate your help.

Thank you :)

Hello Shravani.

I think the error is saying that your input image height dimension (which is 323) does not equal to data mean height dimension (which is 256). 

If you are using imagenet data mean file, I believe the data mean file has a dimension of 256x256. Thus, I believe the imagenet CNN accepts 256x256 images (height 256) as input image. 

If you re-size your input image to 256x256 then the error message should go away. 

Best,

Dong Ki Kim

Thanks for the quick response.

I though the model definition we used crops the images to 227 (but the error shows 323). If I am wrong, please correct me. Could you guide me on how to resize the input images.
transform_param
  {
    crop_size: 227
    mirror: false
    mean_file: "caffeMasterDir/data/ilsvrc12/imagenet_mean.binaryproto"
  }

I have used the mean file provided in  ..caffeMasterDir/data/ilsvrc12/imagenet_mean.binaryproto.

For the statement net.CopyTrainedLayersFrom("/home/dkkim930122/caffe-cudnn/examples/imagenet/caffe_reference_imagenet_model");  in your program, I instead used net.CopyTrainedLayersFrom("caffeMasterDir/models/bvlc_reference_caffenet/bvlc_reference_caffenet.caffemodel");  .

I have downloaded bvlc_reference_caffenet.caffemodel from Model zoo.

I think there could be many answers to this, but I personally use gimp program or use my personal program written in Python to re-size images to 256x256 BEFORE using Caffe. AFTER resizing input image to 256x256, I use Caffe. 

Hope this helps!

[Vasant Srinivasan]

You could also use cv::size from opencv.

Ohh! so we manually resize the images! I thought there is a way to mention in the model definition (prototxt) file that the input images are to be cropped. what does the parameter crop-size:227 do?

I resized and it works well. The image fish-bike.jpg got mapped to class 770. Is there a way I could extract the real name of the class (like 'fish') . Could you point me to the file that has (label num - label name) information.

Thanks so much guys!!

Dear Dong Ki Kim, 

 

Hello. I'm the new in caffe, and I see your code and rewrite it.  As follows.

   But I got an error .


error: 'class caffe::MemoryDataLayer<float>' has no member named 'AddMatVector'   

memory_data_layer->AddMatVector(imageVector,labelVector);
                        ^      

    File not found: /home/server/test/mainwindow.cpp

I confirmed the function(AddMatVector) in the file , memory_data_layer.hpp.

   
 

could you help me? 

 

If my description is not clear enough, I will make it clearly. Thank you.
