# LibreRTDETRv2r101

RT-DETRv2 ResNet-101_vd COCO detector, repackaged for the [LibreYOLO](https://github.com/LibreYOLO/libreyolo) framework.

## Source

Derived from [https://github.com/lyuwenyu/RT-DETR](https://github.com/lyuwenyu/RT-DETR) at commit `a21d516aca15da57e65f35c47659c7535ad2b6b3` and upstream checkpoint:
`https://github.com/lyuwenyu/storage/releases/download/v0.1/rtdetrv2_r101vd_6x_coco_from_paddle.pth`.

The ResNet_vd backbone lineage traces to PaddleClas. Both projects are Apache-2.0 licensed.

## Modifications

EMA weights were unwrapped, `encoder.input_proj` keys were remapped from named submodules to LibreYOLO's sequential layout where required, and the checkpoint was saved with LibreYOLO metadata schema v1.0. Learned tensors are unchanged apart from layout-compatible key names.

## 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`.
