# TTA-COCO-FasterRCNN-R50

Faster R-CNN ResNet-50-FPN trained on COCO (91-class id space), re-hosted for the
TTA-Evaluation-Harness as the two-stage detection source model (sibling of
`WNJXYK/TTA-COCO-DETR-R50`).

`model.safetensors` is the torchvision `fasterrcnn_resnet50_fpn` COCO `state_dict`
(`FasterRCNN_ResNet50_FPN_Weights.DEFAULT`, Apache-2.0). The harness loads it into
a real-`BatchNorm2d` backbone (`weights_backbone=None`, `strict=False`) so BN-based
test-time adaptation has a genuine adaptation surface. Pinned by `revision: v1.0`.
