SOLIDER on [Person Re-identification]

This repo provides details about how to use SOLIDER pretrained representation on person re-identification task. We modify the code from TransReID, and you can refer to the original repo for more details.

Installation and Datasets

We use python version 3.7, PyTorch version 1.7.1, CUDA 10.1 and torchvision 0.8.2. More details of installation and dataset preparation can be found in TransReID-SSL.

Prepare Pre-trained Models

You can download models from SOLIDER, or use SOLIDER to train your own models. Before training, you should convert the models first.

python convert_model.py path/to/SOLIDER/log/lup/swin_tiny/checkpoint.pth path/to/SOLIDER/log/lup/swin_tiny/checkpoint_tea.pth

Training

We utilize 1 GPU for training. Please modify the MODEL.PRETRAIN_PATH, DATASETS.ROOT_DIR and OUTPUT_DIR in the config file.

sh run.sh

Test

sh runtest.sh

Performance

Method	Model	MSMT17 (w/o RK)	Market1501 (w/o RK)	MSMT17 (with RK)	Market1501 (with RK)
SOLIDER	Swin Tiny	67.4/85.9 (Link,Log)	91.6/96.1 (Link,Log)	81.5/89.2	95.3/96.6
SOLIDER	Swin Small	76.9/90.8 (Link,Log)	93.3/96.6 (Link,Log)	86.5/91.7	95.4/96.4
SOLIDER	Swin Base	77.1/90.7 (Link,Log)	93.9/96.9 (Link,Log)	86.5/91.7	95.6/96.7

• mAP/Rank1 are used as evaluation metric, RK indicates whether re-ranking is involved.
• RK shares the same models with w/o RK.
• We use the pretrained models from SOLIDER.
• The semantic weight is set to 0.2 in these experiments.
