MAR: MultilAbel Reference Learning

This repo contains the source code for our CVPR'19 work Unsupervised person re-identification by soft multilabel learning (the paper and the supplementary material is available). Our implementation is based on Pytorch. In the following is an instruction to use the code to train and evaluate the MAR model on the Market-1501 dataset.

Prerequisites

  1. Pytorch 1.0.0
  2. Python 3.6+
  3. Python packages: numpy, scipy, pyyaml/yaml, h5py
  4. [Optional] MATLAB, if you need to customize used datasets.

Data preparation

If you simply want to run the demo code without further modification, you might skip this step by downloading all required data from BaiduPan with password "tih8", and put all of them into /data/. Alternatively, you can find processed MSMT17 here and Market/Duke here.

  1. Pretrained model

    Please find the pretrained model (pretrained using softmax loss on MSMT17) in BaiduPan (password: tih8) or GoogleDrive. After downloading pretrained_MSMT17.pth, please put it into /data/.

  2. Target dataset

    Download the Market-1501 dataset, and unzip it into /data. After this step, you should have a folder structure:

    • data
      • Market-1501-v15.09.15
        • bounding_box_test
        • bounding_box_train
        • query

    Then run /data/construct_dataset_Market.m in MATLAB. If you prefer to use another dataset, just modify the MATLAB code accordingly. The processed Market-1501 and DukeMTMC-reID are available in BaiduPan and GoogleDrive.

  3. Auxiliary (source) dataset

    Download the MSMT17 dataset, and unzip it into /data. After this step, you should have a folder structure:

    • data
      • MSMT17_V1
        • train
        • test
        • list_train.txt
        • list_query.txt
        • list_gallery.txt

    Then run /data/construct_dataset_MSMT17.m in MATLAB. If you prefer to use another dataset, just modify the MATLAB code accordingly. Again, the processed MSMT17 is available in BaiduPan and Mega.

Run the code

Please enter the main folder, and run

python src/main.py --gpu 0,1,2,3 --save_path runs/debug

where "0,1,2,3" specifies your gpu IDs. If you are using gpus with 12G memory, you need 4 gpus to run in the default setting (batchsize=368). If you set a small batch size, please do not forget to lower the learning rate as the gradient would be stronger for a smaller batch size. Please also note that since I load the whole datasets into cpu memory to cut down IO overhead, you need at least 40G cpu memory. Hence I recommend you run it on a server.
