Is there a way to create arrays and datasets with unnamed dimensions?

No. Xarray's data model requires all dimensions to have a name.

Xarray allows you to create DataArrays without specifying dimensions:

python import xarray as xr import numpy as np da = xr.DataArray(np.zeros((4, 5)))

Xarray will choose dimension names in this case (dim_0, dim_1, etc.)

This doesn't work with creating Datasets, because you have to specify all variables' dimensions in the Dataset constructor.

I imagine that unnamed dimensions would break lots of internal Xarray logic.
