I'm using the official example scripts/configs for the officially supported tasks/models/datasets.
main branch https://github.com/open-mmlab/mmdetection3d
The definition of DIoU loss:
And the distance between box_pred center and box_gt center in mmdet3d is implemented as follows: link
I think here should be:
r2 = ((box3d1[..., :3] - box3d2[..., :3])**2).sum(dim=-1)
If I have any misconceptions, please kindly point them out. I would appreciate a detailed response.

It seems to be a mistake. We will try to re-train the model with the correct loss, thanks for your report!
