Introduction

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.

Methods

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. Our training logs are in [Google Drive].

12 epoch setting

24 epoch setting

36 epoch setting

Installation

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

git clone https://github.com/IDEA-Research/DINO.git
cd DINO

2. Install Pytorch and torchvision

Follow the instruction on https://pytorch.org/get-started/locally/.

# an example:
conda install -c pytorch pytorch torchvision

3. Install other needed packages

pip install -r requirements.txt

4. Compiling CUDA operators

cd models/dino/ops
python setup.py build install
# unit test (should see all checking is True)
python test.py
cd ../../..

Data

Please download COCO 2017 dataset and organize them as following:

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

Run

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/DINO_eval.sh /path/to/your/COCODIR /path/to/your/checkpoint

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

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/DINO_train.sh /path/to/your/COCODIR

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/DINO_train_submitit_swin.sh /path/to/your/COCODIR /path/to/your/pretrained_backbone 

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/DINO_train_submitit.sh /path/to/your/COCODIR

# for DINO-5scale: 49.4
bash scripts/DINO_train_submitit_5scale.sh /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/DINO_train_dist.sh /path/to/your/COCODIR

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.

Links

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