Hi, what's the difference between these two pretrained backbones?

[tyxsspa]

I found two backbones that used in config, one is v2-99 fcos3d_vovnet_imgbackbone-remapped.pth and another is dd3d_det_final.pth , and dd3d is used for nuScenes TEST, I wonder what's the difference? Thanks~!

fcos3d_vovnet_imgbackbone-remapped.pth is first pretrained on DDAD15M dataset and further trained on nuScenes train set with FCOS3D.

dd3d_det_final.pth is first pretrained on DDAD15M dataset and further trained on nuScenes trainval set with DD3D.

The 'dd3d_det_final.pth' may have overfitted of the val set, the result will be inflated. So if you report the result on val set，you must use the 'fcos3d_vovnet_imgbackbone-remapped.pth'.

Got it, thanks!
