OpenUnReID is an open-source PyTorch-based codebase for both unsupervised learning (USL) and unsupervised domain adaptation (UDA) in the context of object re-ID tasks. It provides strong baselines and multiple state-of-the-art methods with highly refactored codes for both pseudo-label-based and domain-translation-based frameworks. It works with Python >=3.5 and PyTorch >=1.1.
We are actively updating this repo, and more methods will be supported soon. Contributions are welcome.
- Distributed training & testing with multiple GPUs and multiple machines.
- High flexibility on various combinations of datasets, backbones, losses, etc.
- GPU-based pseudo-label generation and k-reciprocal re-ranking with quite high speed.
- Plug-and-play domain-specific BatchNorms for any backbones, sync BN is also supported.
- Mixed precision training is supported, achieving higher efficiency.
- A strong cluster baseline, providing high extensibility on designing new methods.
- State-of-the-art methods and performances for both USL and UDA problems on object re-ID.

Some parts of openunreid are learned from torchreid and fastreid. We would like to thank for their projects, which have boosted the research of supervised re-ID a lot. We hope that OpenUnReID could well benefit the research community of unsupervised re-ID by providing strong baselines and state-of-the-art methods.
This project is developed by Yixiao Ge (@yxgeee), Tong Xiao (@Cysu), Zhiwei Zhang (@zwzhang121).
