PyTorch Person Re-identification Models

We collected some ReID models from open-source projects and provided a unified interface to access them. We retrained these models on three datasets: Market1501, DukeMTMCReID, and MSMT17 using the original open-source code and can automatically load these trained model weights at runtime. For specific usage examples, see test.py.

Highlights

We rewrite a CUDA-accelerated version of the ReID evaluation code, which has a huge speedup compared to the previous numpy version. For details, see reid_models/evaluate/eval_function.py.
For each third-party ReID project, we provide a way to dynamically register the model, as seen reid_models/modeling/third_party_models/FastReID/__init__.py. We will expand more models in the future.
We provide some useful visualization, training and testing tools, as seen in tools
We provide an efficient pre-training code for the ImageNet1k dataset, based on the accelerate library, as see in tools/imagenet_pretrain.py
