756415834 MDU6SXNzdWU3NTY0MTU4MzQ= 4647 DataArray transpose inconsistent with Dataset Ellipsis usage 15331990 closed 0     7 2020-12-03T17:52:16Z 2021-01-05T23:45:03Z 2021-01-05T23:45:03Z CONTRIBUTOR      

This works: import xarray as xr ds = xr.tutorial.open_dataset('air_temperature') ds.transpose('not_existing_dim', 'lat', 'lon', 'time', ...)

This doesn't (subset air): import xarray as xr ds = xr.tutorial.open_dataset('air_temperature') ds['air'].transpose('not_existing_dim', 'lat', 'lon', 'time', ...)

The error message is a bit inaccurate too since I do have Ellipsis included; might be related to two calls of: dims = tuple(utils.infix_dims(dims, self.dims)) ```

ValueError: ('not_existing_dim', 'lat', 'lon', 'time') must be a permuted list of ('time', 'lat', 'lon'), unless ... is included

Traceback ...
