ucr-ccreid's Introduction

UCR

Implementation of paper "Unsupervised Lifelong Person Re-identification via Contrastive Rehearsal".

Installation

conda create -n env_ucr python=3.6
source activate env_ucr 
pip install numpy torch==1.4.0 torchvision==0.5.0 h5py six Pillow scipy sklearn metric-learn tqdm faiss-gpu==1.6.3
python setup.py develop

Prepare Datasets

cd examples && mkdir data

Download the raw datasets Market-1501, Cuhk-Sysu, MSMT17, VIPeR, PRID2011, GRID, iLIDS, CUHK01, CUHK02, SenseReID, CUHK03 and 3DPeS, and then unzip them under the directory like
