Needs pip install lamindb and network access to the Lamin database, which is limited during the alpha. If it fails, use the Client tab.
import lamindb as ln
db = ln.DB("scverse/spatialdata-db")

sdata = artifact.load() # cache, then load into memory
group = artifact.open() # stream without downloading

# sddb client: download the .zarr into data/
