UserWarning when renaming DataArray coordinates

[mgorfer]

I have code which renames a DataArray and also coordinates in that DataArray

        out = da_pressure_levels_monthly.rename(alt_var_name).rename(
            **{
                "pressure": pres_var_name,
                "latitude_bins": lat_var_name,
                "time": time_var_name,
            }
        )

Recently, I am getting the UserWarning
UserWarning: rename 'time' to 'time' does not create an index anymore. Try using swap_dims instead or use set_index after rename to create an indexed coordinate.

I don't want to create an index, just renaming is okay in my use case. Is there anything I should change in my code?
Or anything I can do to silence the warning if things are looking good in my code?

Dear everyone,
I want to bump this and ask for the best approach for my UserWarning.

Hi @mgorfer, since all you want is just renaming, you can safely ignore this warning, which will be dropped eventually.

Thank you for your reply!
Then I will just leave it at this and wait for the warning to be dropped.
