sota of reid model

Primary LanguagePython

ReID_baseline

Baseline model (with bottleneck) for person ReID (using softmax and triplet loss). This is PyTorch version, mxnet version has a better result and more SOTA methods.

We support

  • multi-GPU training
  • easy dataset preparation
  • end-to-end training and evaluation

Get Started

  1. cd to folder where you want to download this repo

  2. Run git clone https://github.com/L1aoXingyu/reid_baseline.git

  3. Install dependencies:

  4. Prepare dataset

    Create a directory to store reid datasets under this repo via

    cd reid_baseline
    mkdir data
    1. Download dataset to data/ from http://www.liangzheng.org/Project/project_reid.html
    2. Extract dataset and rename to market1501. The data structure would like:
    market1501/
        bounding_box_test/
        bounding_box_train/
    
  5. Prepare pretrained model if you don't have

    from torchvision import models
    models.resnet50(pretrained=True)

    Then it will automatically download model in ~.torch/models/, you should set this path in config.py

Train

You can run

bash scripts/train_triplet_softmax.sh

in reid_baseline folder if you want to train with softmax and triplet loss. You can find others train scripts in scripts.
