I am using Opencv 3.1.0 on ubuntu 14.04. I have successfully built Opencv and wanted to try reading a caffe model and classifying.

I used the program and models from this tutorial

I am able to compile the program but running it gives me the error below-

OpenCV Error: Unspecified error (FAILED: fs.is_open(). Can't open "bvlc_googlenet.prototxt") iReadProtoFromTextFile, file /home/kevmepls/opt/opencv_contrib/modules/dnn/src/caffe/caffe_io.cpp, line 1077
Can't load network by using the following files: 
prototxt:   bvlc_googlenet.prototxt
caffemodel: bvlc_googlenet.caffemodel
bvlc_googlenet.caffemodel can be downloaded here:

I don't understand why it can't read the models?

hmm, a simple ifstream failed to open . not much magic here. it'sprobably about the path, can you try to put all files & your binary into te same folder ?

Hi break, I actually put all the models and image in the same folder with the program and still the error comes.

Sorry guys, it was a silly mistake. There was a space in the beginning of the caffemodel file name, so it couldn't read it. Later I got another error about failing to parse NetParameter file, so I had to download the caffemodel again and it got solved.

Now I have another error, so I will spend some time to see if there is a similar error online, or else I will put it as a separate issue.
