Description:

Normally, it should not be necessary to call this method in user code, because all xarray functions should either work on deferred data or load data automatically. However, this method can be necessary when working with many file objects on disk. Parameters **kwargs : dict Additional keyword arguments passed on to ``dask.array.compute``.
