LibreFasterRCNNl

LibreFasterRCNNl

Modernized Faster R-CNN (ResNet-50 FPN v2 enhanced-recipe variant), repackaged for LibreYOLO. This is a torchvision COCO recipe, not the original 2015 VGG16 architecture.

from libreyolo import LibreYOLO

model = LibreYOLO("LibreFasterRCNNl.pt")
results = model.predict("image.jpg")

Modifications

Checkpoint metadata was added for LibreYOLO's v1.0 schema. Learned tensors and state-dict keys are unchanged. The native LibreYOLO graph loads the official state dict strictly and has exact eager parity at the RPN head, RoI predictor, and final detections. See weights/convert_faster_rcnn_weights.py in the LibreYOLO source repository.
