Model ZOO

We provide a set of baseline results and trained models available for download:

Name	Backbone	epochs	AP (Reproduced / Reported)	download
Deformable-DETR	R50	100	69.3 / 68.8	model
Deformable-DETR	R101	100	69.9 / 70.0	model
Deformable-DETR	Swin Large	100	73.3 / 73.1	model
H-Deformable-DETR	R50	100	70.9	model
H-Deformable-DETR	R101	100	71.0	model
H-Deformable-DETR	Swin Large	100	74.9	model

• We use 8 V-100 GPUs and batch_size = 8 for all experiments.
• We tune the droppath of Swin Large backbone from 0.3 to 0.5 for experiments of baseline and our method.

Installation

We test our models under python=3.7.10,pytorch=1.10.1,cuda=10.2. Other versions might be available as well.

Please follow get_started.md to install the repo.

Run

To train a model using 8 cards

bash ./tools/dist_train.sh <config_path> 8

To eval a model using 8 cards

bash ./tools/dist_test.sh  <config_path> <checkpoint_path> 8 --eval keypoints
