[2022/9/22]: We release a toolbox detrex that provides state-of-the-art Transformer-based detection algorithms. It includes DINO with better performance. Welcome to use it!

[2022/9/18]: We organize ECCV Workshop Computer Vision in the Wild (CVinW), where two challenges are hosted to evaluate the zero-shot, few-shot and full-shot performance of pre-trained vision models in downstream tasks:

$\qquad$ [Workshop] $\qquad$ [IC Challenge] $\qquad$ [OD Challenge]
[2022/8/6]: We update Swin-L model results without techniques such as O365 pre-training, large image size, and multi-scale test. We also upload the corresponding checkpoints to Google Drive. Our 5-scale model without any tricks obtains 58.5 AP on COCO val.
[2022/7/14]: We release the code with Swin-L and Convnext backbone.
[2022/7/10]: We release the code and checkpoints with Resnet-50 backbone.
[2022/6/7]: We release a unified detection and segmentation model Mask DINO that achieves the best results on all the three segmentation tasks (54.7 AP on COCO instance leaderboard, 59.5 PQ on COCO panoptic leaderboard, and 60.8 mIoU on ADE20K semantic leaderboard)! Code will be available here.
[2022/5/28] Code for DN-DETR is available here.
[2020/4/10]: Code for DAB-DETR is avaliable here.
[2022/3/8]: We reach the SOTA on MS-COCO leader board with 63.3AP!
[2022/3/9]: We build a repo Awesome Detection Transformer to present papers about transformer for detection and segmenttion. Welcome to your attention!

SOTA results


We present DINO (DETR with Improved deNoising anchOr boxes) with:

  1. State-of-the-art & end-to-end: DINO achieves 63.2 AP on COCO Val and 63.3 AP on COCO test-dev with more than ten times smaller model size and data size than previous best models.
  2. Fast-converging: With the ResNet-50 backbone, DINO with 5 scales achieves 49.4 AP in 12 epochs and 51.3 AP in 24 epochs. Our 4-scale model achieves similar performance and runs at 23 FPS.



Model Zoo

We have put our model checkpoints here [model zoo in Google Drive][model zoo in 百度网盘](提取码"DINO"), where checkpoint{x}_{y}scale.pth denotes the checkpoint of y-scale model trained for x epochs.

We use the environment same to DAB-DETR and DN-DETR to run DINO. If you have run DN-DETR or DAB-DETR, you can skip this step. We test our models under python=3.7.3,pytorch=1.9.0,cuda=11.1. Other versions might be available as well. Click the Details below for more details.

  1. Clone this repo
  1. Install Pytorch and torchvision

Follow the instruction on

# an example:
conda install -c pytorch pytorch torchvision
  1. Install other needed packages
pip install -r requirements.txt
  1. Compiling CUDA operators
cd models/dino/ops
python build install
# unit test (should see all checking is True)
cd ../../..



Please download COCO 2017 dataset and organize them as following:

  ├── train2017/
  ├── val2017/
  └── annotations/
  	├── instances_train2017.json
  	└── instances_val2017.json


1. Eval our pretrianed models

Download our DINO model checkpoint "checkpoint0011_4scale.pth" from this link and perform the command below. You can expect to get the final AP about 49.0.

bash scripts/ /path/to/your/COCODIR /path/to/your/checkpoint
2. Inference and Visualizations

For inference and visualizations, we provide a notebook as an example.

3. Train a 4-scale model for 12 epochs

We use the DINO 4-scale model trained for 12 epochs as an example to demonstrate how to evaluate and train our model.

You can also train our model on a single process:

bash scripts/ /path/to/your/COCODIR
4. Supports for Swin Transformer

To train Swin-L model, you need to first download the checkpoint of Swin-L backbone from link and specify the dir of the pre-trained backbone when running the scripts. Here is an example.

bash scripts/ /path/to/your/COCODIR /path/to/your/pretrained_backbone 
5. Distributed Run

As the training is time consuming, we suggest to train the model on multi-device.

If you plan to train the models on a cluster with Slurm, here is an example command for training:

# for DINO-4scale: 49.0
bash scripts/ /path/to/your/COCODIR

# for DINO-5scale: 49.4
bash scripts/ /path/to/your/COCODIR

Notes: The results are sensitive to the batch size. We use 16(2 images each GPU x 8 GPUs for DINO-4scale and 1 images each GPU x 16 GPUs for DINO-5scale) by default.

Or run with multi-processes on a single node:

# for DINO-4scale: 49.0
bash scripts/ /path/to/your/COCODIR
6. Training/Fine-tuning a DINO on your custom dataset

To train a DINO on a custom dataset from scratch, you need to tune two parameters in a config file:

  • Tuning the num_classes to the number of classes to detect in your dataset.
  • Tuning the parameter dn_labebook_size to ensure that dn_labebook_size >= num_classes + 1

To leverage our pre-trained models for model fine-tuning, we suggest add two more commands in a bash:

  • --pretrain_model_path /path/to/a/pretrianed/model. specify a pre-trained model.
  • --finetune_ignore label_enc.weight class_embed. ignore some inconsistent parameters.


Our model is based on DAB-DETR and DN-DETR.
