> tfidf_test.py is failing. Full error message is given below.
> ValueError: The key coder "TupleCoder[BytesCoder, FastPrimitivesCoder]" for
> GroupByKey operation "GroupByKey" is not deterministic. This may result in
> incorrect pipeline output. This can be fixed by adding a type hint to the
> operation preceding the GroupByKey step, and for custom key classes, by
> writing a deterministic custom Coder. Please see the documentation for more
> details.
> Seems to be due to following commit (passes without that).
