/Objectness.cpp:304 not enough training sample for r[0] = 2. P = 0, N = 6760

Hi bittnt,
Thanks a lot for this code.
I ran this algorithm on my dataset and I got the error which has troubled me for a long time.
The error report is :
Warning /home/bnnt/software/Objectness-master/Src/Objectness.cpp:304 not enough training sample for r[0] = 2. P = 0, N = 6760
xp.size = 0 xN.size = 6760
OpenCV Error: Assertion failed (!fixedSize() || ((Mat*)obj)->size.operator()() == Size(_cols, _rows)) in create, file /home/bnnt/opencv-3.1.0/modules/core/src/matrix.cpp, line 2232
terminate called after throwing an instance of 'cv::Exception'
what(): /home/bnnt/opencv-3.1.0/modules/core/src/matrix.cpp:2232: error: (-215) !fixedSize() || ((Mat*)obj)->size.operator()() == Size(_cols, _rows) in function create

I find there no positive samples in "xP".
Do you know how to fix it?
Thanks a lot.
