Access preflight and acquisition

CLI

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

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

Python

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

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

Loader example

This entry includes a standard DatasetSample loader.

from pathlib import Path
from eyedatahub.datasets.registry import REGISTRY

data_dir = Path('~/.eyedatahub/data').expanduser()
ds = REGISTRY.get_dataset('ravir')
samples = ds.load(data_dir, split='test')
for s in samples[:5]:
    print(s.sample_id, s.label, s.image_path)
