Is it assumed that there is only one object in each cell?

Thanks for sharing the codes. I am little confused about the way to generate the ground truth labels. Hope you could help me point out what I might misunderstand. Thanks.

When generating training labels in https://github.com/leeyoshinari/YOLO_v2/blob/aa9bf78ecf461a1a3924e466024f8417d23197aa/pascal_voc.py#L61-L76, won't the labels be overwritten if two objects in the same cell? If that is the case, does that mean the first object can not be used for training?

YOLOv2假定了每个cell至多含有一个grounth truth，而在实际上基本不会出现多于1个的情况。
