Why not use rotate_nms_gpu?

[godspeed1989]

Hi,
I notice function rotate_nms() in box_torch_ops.py
You use rotate_nms_cc instead of rotate_nms_gpu

second.pytorch/second/pytorch/core/box_torch_ops.py

Line 485 in fb28d7b

ret = np.array(rotate_nms_cc(dets_np, iou_threshold), dtype=np.int64)

My question is why not use faster GPU version NMS?

Thanks in advance.

1. after filter boxes by score threshold, lots of boxes are filtered and can't get significant speed increase with gpu rnms.
2. the gpu version is a little unstable.

Thanks a lot
