Access preflight and acquisition
- CLI
- Python
# Read-only preflight
eyehub download coph100 --data-dir ./data --dry-run --json
# Explicit transfer, only when preflight reports supported behavior
eyehub download coph100 --data-dir ./data
from eyedatahub.acquisition import preflight_dataset
from eyedatahub.datasets.registry import REGISTRY
ds = REGISTRY.get_dataset('coph100')
print(preflight_dataset(ds, './data')) # no transfer
