Introduction

This is the PyTorch implementation for Adaptive Graph Representation Learning for Video Person Re-identification.

Get started

git clone https://github.com/weleen/AGRL.pytorch /path/to/save
pip install -r requirements.txt
cd torchreid/metrics/rank_cylib && make

Dataset

create dataset directory

mkdir data

Prepare datasets:

    ├── prid_2011.zip
    ├── splits_prid2011.json
    └── train_test_splits_prid.mat

pose.json is obtained by running AlphaPose, we put the files on Baidu Netdisk (code: luxr) and Google Driver(only pose.json, please download the model from Baidu Netdisk).

More details could be found in DATASETS.md.

Train

bash scripts/train_vidreid_xent_htri_vmgn_mars.sh

To use multiple GPUs, you can set --gpu-devices 0,1,2,3.

Note: To resume training, you can use --resume path/to/model to load a checkpoint from which saved model weights and start_epoch will be used. Learning rate needs to be initialized carefully. If you just wanna load a pretrained model by discarding layers that do not match in size (e.g. classification layer), use --load-weights path/to/model instead.

Please refer to the code for more details.

Test

create a directory to store model weights mkdir saved-models/ beforehand. Then, run the following command to test

bash scripts/test_vidreid_xent_htri_vmgn_mars.sh

All the model weights are available.

Model

All the results tested with 4 TITAN X GPU and 64GB memory.
