c++ CPU mode how to use nms

[dbrazey]

Hello,

I am writing because I have some troubles using py faster rcnn in c++.
In GPU mode, everything is ok : I can compile the library, learn using provided scripts and I can detect objects with my c++ code.

However, I am trying to use the library to detect objects only (no training) on a laptop without GPU card. In order to do this, I compile the library in CPU mode following the instructions found here :

#123

The file gpu_nms.so is not generated any more, I only get the cpu_nms.so file.
Then, when I compile my c++ code, I get the following error

/tmp/ccUNhddW.o : Dans la fonction « CFRCNN::DetectObjects(cv::Mat_) » :
FRCNN.cpp:(.text+0xcac) : référence indéfinie vers « nms(int, int_, float const_, int, int, float, int) »
collect2: error: ld returned 1 exit status

In GPU mode, the following c++ function call worked fine
#include "gpu_nms.hpp"
_nms(keep, &nbObjects_nms, sorted_pred_cls, nbRois, 5, m_nmsThreshold, 0);`

but the function _nms seems to be different in cpu_nms.so.
I didn't found any header like "cpu_nms.hpp" in the library.
How to use this function in CPU mode ?

Thank you for your help :)
