title: Obj and No Obj fields in YOLOv2 darknet always 0
body: <p>I am training YOLOv2 model on custom data. It has 6 classes of data. I follow <a href="https://github.com/AlexeyAB/darknet" rel="nofollow noreferrer">AlexyAB's darknet</a> to train for custom training. The dataset I am using is <a href="https://s3-us-west-2.amazonaws.com/ai2-vision-datasets/COQE_dataset/COQE_dataset.tar.gz" rel="nofollow noreferrer">COQE dataset</a> mentioned in this <a href="https://arxiv.org/pdf/1701.02718.pdf" rel="nofollow noreferrer">paper</a>.</p>
  
  <p>The problem I am facing is whenever I start training the Obj and No-Obj attribute goes to zero.</p>
  
  <p>In the cfg file, my batch=64, subdivisions=8, filters=55, classes=6, everything else is similar to yolo-voc.vfg</p>
