In other words, why does A longer example: ```python import dask.array as da import xarray as xr x = da.random.randint(1, 10, size=(100, 25)) ds = xr.Dataset(dict(a=xr.DataArray(x, dims=('x', 'y')))) type(ds.a.data) dask.array.core.Array Recreate the dataset with the same array, but also redefine the dimensionsds2 = xr.Dataset(dict(a=(('x', 'y'), ds.a)) type(ds2.a.data) numpy.ndarray ``` |
