Access preflight and acquisition
- CLI
- Python
# This route requires upstream human action; no transfer starts.
eyehub download retouch --data-dir ./data --dry-run --json
# Follow the official instructions shown by preflight.
from eyedatahub.acquisition import preflight_dataset
from eyedatahub.datasets.registry import REGISTRY
ds = REGISTRY.get_dataset('retouch')
print(preflight_dataset(ds, './data')) # returns manual_access_blocked
