How to export ExDark in Yolov3 format for training? #19

I noticed that the bounding boxes were all in pixel values, so I was wondering if there's any way to export/change the ground truth boxes from that to the yolov3 notation other than going into every txt file and manually changing it?

Yolov3 notation

object class x value of center of ground truth/image width y value of center of ground truth/image height height of ground truth/image width width of ground truth/image width

Example: 1 0.716797 0.395833 0.216406 0.147222
