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")
artifact = db.Artifact.get("ViMUTdOhwg3SMDQc") # stem uid: Lamin resolves it to the latest version
sdata = artifact.load() # cache, then load into memory

# sddb client: download the .zarr into data/
sddb-cli download ViMUTdOhwg3SMDQc0000 --dest data/
# or lamin: cache the dataset and print its local path
lamin load https://lamin.ai/scverse/spatialdata-db/artifact/ViMUTdOhwg3SMDQc
