The example the doc build doesn't like: ```python ds = xr.tutorial.load_dataset("rasm") ds.to_zarr("rasm.zarr", mode="w") import zarr

zgroup = zarr.open("rasm.zarr") print(zgroup.tree()) dict(zgroup["Tair"].attrs) `` I'll need to look into therasm` dataset to figure out why there is a warning now.
