inf bbox loss when using cal_giou_3d ( but the iou is right)

[YuQiao0303]

Hi author, Thank you for your nice work. I encountered a case where I get bbox_iou of 0.7304, but bbox_loss: -inf.

After that it's: CUDA kernel failed : invalid configuration argument.

Should I modify giou_loss = 1. - iou3d + (v_c - u3d) / v_c as giou_loss = 1. - iou3d + (v_c - u3d) / (v_c + 1e-14)?

Thank you!
