The official repository for PASS: Part-Aware Self-Supervised Pre-Training for Person Re-Identification ECCV2022.

Requirements

Installation

pip install -r requirements.txt

We recommend to use /torch=1.8.0 /torchvision=0.9.0 /timm=0.3.4 /cuda>11.1 /faiss-gpu=1.7.2/ A100 for training and evaluation. If you find some packages are missing, please install them manually. You can refer to DINO, TransReID and cluster-contrast-reid to install the environment of pre-training, supervised ReID and unsupervised ReID, respectively. You can also refer to TransReID-SSL to install the whole environments.

Prepare Datasets

mkdir data

Download the datasets:

• Market-1501
• MSMT17
• LUPerson. We don't have the copyright of the LUPerson dataset. Please contact authors of LUPerson to get this dataset.

Then unzip them and rename them under the directory like

Please download pre-trained models and put them into your custom file path.

ReID performance

We have reproduced the performance to verify the reproducibility. The reproduced results may have a gap of about 0.1~0.2% with the numbers in the paper.
