Thanks @shoyer

I also noticed that the .sel method is working wrong too after the selection, python In [9]: ds.isel(xy=ds['x'] < 4).sel(x=5) # should be KeyError Out[9]: <xarray.DataArray (y: 0)> array([], dtype=int64) Coordinates: * y (y) int64 Probably better to call pd.MultiIndex.remove_unused_levels() after each selection. I'll send a fix.
