Layout Analysis
D-FINE Stage-2 B2 layout model with 12 classes. Detects page regions; text recognition and reading order are handled by OXR.
Files
last.pth: inference-only model weights (no optimizer or training state).metadata.json: model identity, architecture, preprocessing, class IDs, checkpoint size and SHA-256 (schema version 1).
model_version is a public release version (major.minor.patch), not a
training-run identifier.
Usage
Use the LA inference service in the OXR code repository at
services/layout_analyze/. Mount this directory into the service and set
MODEL_PATH to the mounted last.pth path.
The matching LA service reads metadata.json next to the checkpoint at startup
and validates its supported architecture, preprocessing, class IDs and weight
integrity. Both files must be mounted. MODEL_METADATA_PATH can override the
metadata path. Unsupported metadata or a mismatched checkpoint fails startup.
This is not a Transformers AutoModel configuration. Device, precision and
CUDA Graph settings are selected by the service, not by the model metadata.
Checkpoint verification:
shasum -a 256 layout_analysis/last.pth
