Migrate

Step-by-step guides for moving an existing evaluation pipeline onto vernier. Each guide covers the API mapping, behavioural differences, and the one or two sentinel/quirk traps most likely to affect real workloads.

• From pycocotools — the upstream case; covers the COCOeval shim and patch_pycocotools drop-in.
• From faster-coco-eval — the divergent-stance case; vernier's auditable parity contract vs faster-coco-eval's opaque quirk fixes.
• From panopticapi — panoptic-quality (PQ).
• From lvis-api — long-tail / federated detection.
• From mmsegmentation — semantic segmentation.
