# Model Zoo

- Results are presented in the format of *<Rank-1 (mAP)>*.
- When computing model size and FLOPs, only layers that are used at test time are considered (see `torchreid.utils.compute_model_complexity`).
- Asterisk (\*) means the model is trained from scratch.
- `combineall=True` means all images in the dataset are used for model training.
