The official repository for Self-paced Contrastive Learning with Hybrid Memory for Domain Adaptive Object Re-ID, which is accepted by NeurIPS-2020. SpCL achieves state-of-the-art performances on both unsupervised domain adaptation tasks and unsupervised learning tasks for object re-ID, including person re-ID and vehicle re-ID.
[2020-10-13] All trained models for the camera-ready version have been updated, see Trained Models for details.
[2020-09-25] SpCL has been accepted by NeurIPS on the condition that experiments on DukeMTMC-reID dataset should be removed, since the dataset has been taken down and should no longer be used.
[2020-07-01] We did the code refactoring to support distributed training, stronger performances and more features. Please see OpenUnReID.

cd SpCL
python setup.py developcd examples && mkdir dataDownload the person datasets Market-1501, MSMT17, PersonX, and the vehicle datasets VehicleID, VeRi-776, VehicleX. Then unzip them under the directory like

When training with the backbone of IBN-ResNet, you need to download the ImageNet-pretrained model from this link and save it under the path of logs/pretrained/.
mkdir logs && cd logs
mkdir pretrainedThe file tree should be
SpCL/logs
└── pretrained
└── resnet50_ibn_a.pth.tar
ImageNet-pretrained models for ResNet-50 will be automatically downloaded in the python script.
We utilize 4 GTX-1080TI GPUs for training. Note that
- The training for
SpCLis end-to-end, which means that no source-domain pre-training is required. - use
--iters 400(default) for Market-1501 and PersonX datasets, and--iters 800for MSMT17, VeRi-776, VehicleID and VehicleX datasets; - use
--width 128 --height 256(default) for person datasets, and--height 224 --width 224for vehicle datasets; - use
-a resnet50(default) for the backbone of ResNet-50, and-a resnet_ibn50afor the backbone of IBN-ResNet.

-d veri --logs-dir logs/spcl_usl/veri_resnet50We utilize 1 GTX-1080TI GPU for testing. Note that
- use
--width 128 --height 256(default) for person datasets, and--height 224 --width 224for vehicle datasets; - use
--dsbnfor domain adaptive models, and add--test-sourceif you want to test on the source domain; - use
-a resnet50(default) for the backbone of ResNet-50, and-a resnet_ibn50afor the backbone of IBN-ResNet.
To evaluate the domain adaptive model on the target-domain dataset, run:
CUDA_VISIBLE_DEVICES=0 \
python examples/test.py --dsbn \
-d $DATASET --resume $PATH_OF_MODELTo evaluate the domain adaptive model on the source-domain dataset, run:
CUDA_VISIBLE_DEVICES=0 \
