Hi, when i Modified the backbone network to resnet50, and download it's pretrained model from Net, the model does not converge, when I put the res101（download from your ‘readme’） back on, it works again，I dont know why，hope for your reply。

Hi, I don't know which part you modify.

But one possiblity is that the pretrained model you use have totally different image preprocessing pipelines, esp the normalization steps. we normalize the image using: https://github.com/WangYueFt/detr3d/blob/main/projects/configs/detr3d/detr3d_res101_gridmask.py#L14

Need the backbone ResNet50 be pretrained on nuScenes with FCOS3D network to reproduce the reported NDS (0.373) in the paper?
