We have supported:
- Float16 to save GPU memory based on APEX
- Multiple query evaluation
- Random erasing
- Visualize training curves
- Generate all figures in the paper
- Python 3.6
- GPU Memory >= 15G
- GPU Memory >= 10G (for fp16)
- NumPy
- PyTorch 1.0+
- [Optional] APEX (for fp16)
- Install PyTorch from http://pytorch.org/
- Install torchvision from the source:
git clone https://github.com/pytorch/vision
cd vision
python setup.py install
- [Optinal] You may skip it. Install APEX from the source:
git clone https://github.com/NVIDIA/apex.git
cd apex
python setup.py install --cuda_ext --cpp_ext
- Clone this repo.
git clone https://github.com/NVlabs/DG-Net.git
cd DG-Net/
Our code is tested on PyTorch 1.0.0+ and torchvision 0.2.1+ .
Download the dataset Market-1501
Preparation: put the images with the same id in one folder. You may use
python prepare-market.py # for Market-1501
Note to modify the dataset path to your own path.
We provide our trained model. You may download it from GoogleDrive or (BaiduDisk password: rqvf). You may download and move it to the outputs
.

For more details, please check the README.md
in the ./reid_eval

Please check the README.md
in the ./visual_tools
.
You may use the ./visual_tools/test_folder.py
to generate lots of images and then do the evaluation. The only thing you need to modify is the data path.

tensorflow-gpu
)
You may directly download our trained teacher model from GoogleDrive (or BaiduDisk password: rqvf).
If you want to have it trained by yourself, please check the person re-id baseline repository to train a teacher model, then copy and put it in the ./models

Setup the yaml file. Check out
configs/latest.yaml
. Change the data_root field to the path of your prepared folder-based dataset, e.g.../Market-1501/pytorch
. -
Start training
python train.py --config configs/latest.yaml
Or train with low precision (fp16)
python train.py --config configs/latest-fp16.yaml
Intermediate image outputs and model binary files are saved in outputs/latest
.
- Check the loss log
tensorboard --logdir logs/latest
We provide our generated images and make a large-scale synthetic dataset called DG-Market. This dataset consists of 128,307 images (613MB), about 10 times larger than the original Market-1501. You may download the dataset from GoogleDrive (or BaiduDisk password: qxyh).
Note the format of the camera id and the number of cameras.
For some datasets (e.g., MSMT17), there are more than 10 cameras. You need to modify the preparation and evaluation code to read the double-digit camera id.
For some vehicle re-id datasets (e.g., VeRi) having different naming rules, you also need to modify the preparation and evaluation code.

Other GAN-based methods compared in the paper: we forked the code and made some changes for evaluatation. Thank authors for their great work.
We would also like to thank to the great projects in person re-id baseline, MUNIT and DRIT.
