+# RTMPose-tiny (COCO 17-keypoint) — acaua mirror (pure-PyTorch port)
+
+This is a **pure-PyTorch port** of [RTMPose-tiny](https://github.com/open-mmlab/mmpose/tree/main/projects/rtmpose) hosted under `CondadosAI/` for use with the [acaua](https://github.com/CondadosAI/acaua) computer vision library.
+
+The architecture has been re-implemented in pure PyTorch under `acaua.adapters.rtmpose` — no `mmcv`, no `mmengine`, no `mmpose`, no `trust_remote_code`. The weights in this mirror are converted from the upstream `.pth` checkpoint to safetensors with the acaua adapter's state_dict key naming, and load cleanly via `load_state_dict(strict=True)` into our nn.Module tree.
+
+RTMPose is a **top-down** model: it consumes a person bounding box and predicts COCO 17-keypoint pose. The acaua adapter bundles [`CondadosAI/rtmdet_t_coco`](https://huggingface.co/CondadosAI/rtmdet_t_coco) as the person detector, giving you a single-call `predict(image)` API that returns boxes + keypoints together.

+## Usage
+
+```python
+import acaua
+import supervision as sv
+
+model = acaua.Model.from_pretrained("CondadosAI/rtmpose_t_coco")
+result = model.predict("photo.jpg")
+
+# `result` is a PoseResult: boxes (from RTMDet), keypoints (from RTMPose).
+kp = result.to_supervision()  # supervision.KeyPoints
+sv.EdgeAnnotator(edges=model.skeleton).annotate(scene, kp)
+```

+Redistributed under Apache-2.0, consistent with both the upstream code (mmpose / mmdetection, both Apache-2.0 by OpenMMLab) and the upstream weights declaration. The acaua adapter is a derivative work of the upstream PyTorch implementations — see [`NOTICE`](./NOTICE) for the required attribution chain (code AND weights).
