## Installation

First install FastReID， and then put Partial Datasets in directory datasets. The whole framework of FastReID-DSR is

</div>

and the detail you can refer to
## Datasets

PartialREID---gallery: 300 images of 60 ids, query: 300 images of 60 ids

PartialiLIDS---gallery: 238 images of 119 ids, query: 238 images of 119 ids

OccludedREID---gallery: 1,000 images of 200 ids, query: 1,000 images of 200 ids

## Training and Evaluation

To train a model, run:
```bash
python3 projects/PartialReID/train_net.py --config-file <config.yaml>
```

For example, to train the re-id network with IBN-ResNet-50 Backbone
one should execute:
```bash
CUDA_VISIBLE_DEVICES='0,1,2,3' python3 projects/PartialReID/train_net.py --config-file 'projects/PartialReID/configs/partial_market.yml'
```
