# LibreRTMDets

RTMDet-S COCO detector, repackaged for the [LibreYOLO](https://github.com/LibreYOLO/libreyolo) framework.

## Source

Derived from [https://github.com/open-mmlab/mmdetection](https://github.com/open-mmlab/mmdetection) at commit `cfd5d3a985b0249de009b67d04f37263e11cdf3d` and upstream checkpoint:
`https://download.openmmlab.com/mmdetection/v3.0/rtmdet/rtmdet_s_8xb32-300e_coco/rtmdet_s_8xb32-300e_coco_20220905_161602-387a891e.pth`.

## Modifications

EMA weights were selected from the upstream checkpoint. `data_preprocessor.*` and batch-tracking buffers were omitted, `bbox_head.` keys were renamed to `head.`, and the loaded state dict was saved with LibreYOLO checkpoint metadata schema v1.0. Learned model parameters are otherwise preserved.

## Validation

This file was validated locally with LibreYOLO checkpoint metadata schema v1.0, loaded through `LibreYOLO`, and evaluated on `coco128.yaml` with `workers=0`, `batch=8`, `conf=0.001`, `iou=0.6`.
