Pipeline

framework

Installation

conda create -n clipreid python=3.8
conda activate clipreid
conda install pytorch==1.8.0 torchvision==0.9.0 torchaudio==0.8.0 cudatoolkit=10.2 -c pytorch
pip install yacs
pip install timm
pip install scikit-image
pip install tqdm
pip install ftfy
pip install regex

Prepare Dataset

Download the datasets (Market-1501, MSMT17, DukeMTMC-reID, Occluded-Duke, VehicleID, VeRi-776), and then unzip them to your_dataset_dir.

Training

For example, if you want to run CNN-based CLIP-ReID-baseline for the Market-1501, you need to modify the bottom of configs/person/cnn_base.yml to

DATASETS:
   NAMES: ('market1501')
   ROOT_DIR: ('your_dataset_dir')
OUTPUT_DIR: 'your_output_dir'

then run 

CUDA_VISIBLE_DEVICES=0 python train.py --config_file configs/person/cnn_base.yml

if you want to run ViT-based CLIP-ReID for MSMT17, you need to modify the bottom of configs/person/vit_clipreid.yml to

DATASETS:
   NAMES: ('msmt17')
   ROOT_DIR: ('your_dataset_dir')
OUTPUT_DIR: 'your_output_dir'

then run 

CUDA_VISIBLE_DEVICES=0 python train_clipreid.py --config_file configs/person/vit_clipreid.yml

if you want to run ViT-based CLIP-ReID+SIE+OLP for MSMT17, run:

CUDA_VISIBLE_DEVICES=0 python train_clipreid.py --config_file configs/person/vit_clipreid.yml  MODEL.SIE_CAMERA True MODEL.SIE_COE 1.0 MODEL.STRIDE_SIZE '[12, 12]'

Evaluation

For example, if you want to test ViT-based CLIP-ReID for MSMT17

CUDA_VISIBLE_DEVICES=0 python test_clipreid.py --config_file configs/person/vit_clipreid.yml TEST.WEIGHT 'your_trained_checkpoints_path/ViT-B-16_60.pth'

Note that all results listed above are without re-ranking.

With re-ranking, ViT-CLIP-ReID-SIE-OLP achieves 86.7% mAP and 91.1% R1 on MSMT17.
