Notes

Three sub-archives (BinRushed, Magrabi, MESSIDOR). The MESSIDOR sub-archive is large; if download fails, try the Academic Torrents mirror (infohash eb9dd9216a1c9a622250ad70a400204e7531196d).

Access preflight and acquisition

CLI

# Read-only preflight
eyehub download riga --data-dir ./data --dry-run --json

# Explicit transfer, only when preflight reports supported behavior
eyehub download riga --data-dir ./data

Python

from eyedatahub.acquisition import preflight_dataset
from eyedatahub.datasets.registry import REGISTRY

ds = REGISTRY.get_dataset('riga')
print(preflight_dataset(ds, './data'))  # no transfer
