The problem about the ground truth box for learning reppoints at the initial training stage

[VT-developer]

(1)The code at the 444th line in reppoints_head.py:
(*_, bbox_gt_list_init, candidate_list_init, bbox_weights_list_init,
num_total_pos_init, num_total_neg_init) = cls_reg_targets_init
here, what does the variable "bbox_gt_list_init" represent? It is equivalent to the ground truth boxes?

(2)The same question related to the code at the 477th line in reppoints_head.py.
Is the variable "bbox_gt_list_refine" equivalent to "bbox_gt_list_init"? Is bbox_gt_list_refine same to the ground truth boxes?

Look forward to your replay. Thx.
