# Detectron2 COCO checkpoints (unmodified mirror)

These are unmodified copies of two checkpoints from Meta's
[Detectron2 model zoo](https://github.com/facebookresearch/detectron2/blob/main/MODEL_ZOO.md). They
are mirrored here so that AmalgamationAI can download them with its other models. Upstream only
publishes them on `dl.fbaipublicfiles.com`.

| File | Model | Source | SHA-256 |
|------|-------|--------|---------|
| `model_final_f10217.pkl` | Mask R-CNN R50-FPN 3x (COCO instance segmentation) | <https://dl.fbaipublicfiles.com/detectron2/COCO-InstanceSegmentation/mask_rcnn_R_50_FPN_3x/137849600/model_final_f10217.pkl> | `9a737e290372f1f70994ebcbd89d8004dbb3ae30a605fd915a190fa4a782dd66` |
| `model_final_a6e10b.pkl` | Keypoint R-CNN R50-FPN 3x (COCO person keypoints) | <https://dl.fbaipublicfiles.com/detectron2/COCO-Keypoints/keypoint_rcnn_R_50_FPN_3x/137849621/model_final_a6e10b.pkl> | `48cc65c6f9ff63dabe64bf6082eb257d8515b42b31f0e44ff43cf9470f5107e4` |

They load with the matching `COCO-InstanceSegmentation/mask_rcnn_R_50_FPN_3x.yaml` and
`COCO-Keypoints/keypoint_rcnn_R_50_FPN_3x.yaml` configs. The model zoo is released under the
