# The CCPG Benchmark
A Cloth-Changing Benchmark for Person re-identification and Gait Recognition (CCPG).
The original dataset can be found [here](https://github.com/BNU-IVC/CCPG). The original dataset is not publicly available. You need to request access to the dataset in order to download it.
## Data Pretreatment
```python
python datasets/CCPG/organize_ccpg.py --sil_path 'CCPG/CCPG_D_MASK_FACE_SHOE' --rgb_path 'CCPG/CCPG_G_SIL' --output_path 'CCPG/CCPG-end2end-pkl'
```
## Train
### GatiBase model:
`CUDA_VISIBLE_DEVICES=0,1,2,3 python -m torch.distributed.launch --nproc_per_node=4 opengait/main.py --cfgs ./configs/gaitbase/gaitbase_ccpg.yaml --phase train`
