title: Calling scikit-learn functions from C++
body: <p>Is there way to call scikit-learn's functions from c++? I have the rest of most my code in C++ with opencv. I would like to be able use the classifiers scikit-learn provides. As far as I understand, there's no easy  way - I need to use boost::python or swig. I also came across this project (<a href="https://github.com/spillai/numpy-opencv-converter" rel="nofollow">https://github.com/spillai/numpy-opencv-converter</a>) which shows interop between numpy arrays &lt;==> cv::Mat objects, but I know only how to use to call C++ code from my python script, not the other way around.</p>
