Dataset Layout

COSINE uses simple relative paths so the same checkout can run on a workstation, a cluster, or a NAS. Datasets can be real directories or symlinks.

Task Mapping

Task Code default Notes
FSS COCO-20i datasets/fss/COCO2014 Used by --benchmark coco.
FSS LVIS-92i datasets/fss/LVIS Used by --benchmark lvis.
FSS Pascal-5i datasets/fss/VOC2012 Used by --benchmark pascal.
RefCOCO / RefCOCO+ / RefCOCOg datasets/refer_seg Used by tools/eval_referseg*.py.
DAVIS 2017 datasets/vos/DAVIS/2017 Used by tools/eval_vos_ms.py --dataset D17.
YouTube-VOS 2019 datasets/vos/Youtube-VOS2019 Used by tools/eval_vos_ms.py --dataset Y19.
FSOD COCO/LVIS inference_fsod/datasets/... Detectron2-style configs use coco, coco2017, lvis, and lvissplit.

Validation

After preparing datasets and weights, run:

bash scripts/check_required_assets.sh

This only checks the expected filesystem layout. It does not verify dataset integrity or benchmark annotations.
