Why "anchors" in the "yolo-pose.cfg" file is empty?

This research project implements a real-time object detection and pose estimation method as described in the paper, Tekin et al. "Real-Time Seamless Single Shot 6D Object Pose Prediction", CVPR 2018. (https://arxiv.org/abs/1711.08848).

Why "anchors" in the "yolo-pose.cfg" file is empty? #97

I was trying to implement this amazing project on my own dataset, I found that "anchors" in the cfg/yolo-pose.cfg and cfg/yolo-pose-pre.cfg is empty in this repository, while in btekin/singleshotpose and juanmed/singleshotpose , anchors are not empty, I want to ask what's the purpose of this variable, same with YOLO? is that OK to leave anchors empty? Looking forward to your reply, thanks!

See issue 21 and search for anchor. In short: yes as far as I know anchors has the same meaning as the one in YOLO.

For single object pose estimation, we don't use anchor values, as we don't have to predict multiple 3D bounding boxes per cell. For multiple object pose estimation, though, you should have anchor boxes defined (if you are training on your own dataset, you should compute anchor values yourself using the procedure described in Section 3.2 of the paper.)
