fatal error: opencv2/core/core.hpp caffe framework installation

Question

I'm trying to install Caffe framework with this script: https://gist.github.com/jetsonhacks/acf63b993b44e1fb9528 and I'm getting opencv2/core/core.hpp error.

CXX src/caffe/layers/data_layer.cpp
src/caffe/layers/data_layer.cpp:2:33: 
 fatal error: opencv2/core/core.hpp: No such file or directory
#include <opencv2/core/core.hpp>
                             ^
compilation terminated.
make: *** [.build_release/src/caffe/layers/data_layer.o] Error 1

In the documentation, OpenCV is optional. But that error tells me not. Does such include have nothing to do with OpenCV installation?

Answer 1

Installing opencv for python is not sufficient. You also need to do

sudo apt-get install libopencv-dev

Answer 2

I faced the same problem and solved it just by installing OpenCV. You will find other similar errors, unless you have installed all prerequisites.
