Hey guys,

This is bit of an emergency. I'm struggling to install Caffe on my ubuntu machine to proceed with my Final Year project. When I use the command make all -j8 it gives me the following error. Any help?

src/caffe/util/bbox_util.cpp: In instantiation of ‘void caffe::RboxToPolygon(const Dtype*, caffe::Polygon&) [with Dtype = float; caffe::Polygon = boost::geometry::model::polygon<boost::geometry::model::d2::point_xy<float> >]’:

src/caffe/util/bbox_util.cpp:747:64:   required from here

thanks in advance

This might or might not help you, since I can't give you a solution for that error.
But you could instead try to install caffe via "conda" with:

 conda install -c conda-forge caffe

That might be a faster solution. Also good luck with your project.

What flavor of Caffe are you using? This is not the master branch, as it does not even have anything like bbox_util.

It is a custom caffe. I'm trying this TextBoxes++
