Access preflight and acquisition

CLI

# This route requires upstream human action; no transfer starts.
eyehub download nd_iris_0405 --data-dir ./data --dry-run --json
# Follow the official instructions shown by preflight.

Python

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

ds = REGISTRY.get_dataset('nd_iris_0405')
print(preflight_dataset(ds, './data'))  # returns manual_access_blocked
