class_docstr: YOLO BBox coder.
  
  Following `YOLO <https://arxiv.org/abs/1506.02640>`_, this coder divide
  image into grids, and encode bbox (x1, y1, x2, y2) into (cx, cy, dw, dh).
  cx, cy in [0., 1.], denotes relative center position w.r.t the center of
  bboxes. dw, dh are the same as :obj:`DeltaXYWHBBoxCoder`.
  
  Args:
      eps (float): Min value of cx, cy when encoding.
code: def __init__(self, eps=1e-6):
      super(BaseBBoxCoder, self).__init__()
      self.eps = eps
