TypeError("__init__() got an unexpected keyword argument 'phonemes'") with NeMo

I’m trying to run a skript based on NeMo and am stuck with this error

When trying to run the skript to test this model

So far i was unable to google the solution, i simply did
pip install nemo_toolkit[‘all’]
and
pip install pynini==2.1.5
as suggested by the NeMo installation

any hints?
