Installation

We use python 3.7 and pytorch=0.4

Data preparation

All experiments are done on MARS, as it is the largest dataset available to date for video-based person reID. Please follow deep-person-reid to prepare the data. The instructions are copied here:

1. Create a directory named mars/ under data/.
2. Download dataset to data/mars/ from http://www.liangzheng.com.cn/Project/project_mars.html.
3. Extract bbox_train.zip and bbox_test.zip.
4. Download split information from https://github.com/liangzheng06/MARS-evaluation/tree/master/info and put info/ in data/mars (we want to follow the standard split in [8]). The data structure would look like:

mars/
    bbox_test/
    bbox_train/
    info/

Usage

To train the model, please run

sh run_hypergraphsage_part.sh

Performance

Normaly the model achieves 85.8% mAP and 89.5% rank-1 accuracy. According to my training log, the best model achieves 86.2% mAP and 90.0% top-1 accuracy. This may need adjustion in hyperparameters.
