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.
