Does this mean that the current best pre trained model available on pytorch is Faster R-CNN ResNet-50 FPN version 2 with mAP of 46.7 surpassing the previous best FCOS ResNet-50 FPN of 39.2?

Could you please provide the link to the code and the pre-trained of Faster R-CNN ResNet-50 FPN version 2

@santhoshnumberone Yes but keep in mind that the FCOS was not retrained. It's likely we can do better with it as well if we review the training recipe but that will be reviewed on the future.

The description of this PR gives you all this info. Use the latest main of TorchVision.

@datumbox off the topic

Can't wait to see this DINO: DETR with Improved DeNoising Anchor Boxes for End-to-End Object Detection paper retrained by you in future

@santhoshnumberone We have a dedicated issue for getting such requests at #2707

I strongly recommend commenting the same thing there so that you get visibility and consider it on the future. Having this discussion here is likely to be forgotten/lost.

Hi @datumbox, I'm trying to reproduce this result (fasterrcnn_resnet50_fpn_v2, mAP=46.7) with torchvision 0.19.1. I have two questions:

1. Here (Add FasterRCNN improved weights #5763 (comment)) you mention using run_with_submitit.py, but this script doesn’t seem to be included. Should I substitute it with train.py instead?

2. I’m training on a single machine with 8xV100 GPUs, whereas your configuration uses 4 nodes with 2 GPUs each. How should I adjust the hyperparameters, particularly the learning rate and batch size? The default values in train.py (

Thank you for your help and clarification.
