Hello , I was setting up the datahub with these commands , and after setting up I am getting these following errors .

python -m pip install --upgrade pip wheel setuptools
python -m pip uninstall datahub acryl-datahub || true  # sanity check - ok if it fails
python -m pip install --upgrade acryl-datahub

When I check the version datahub --version it is sending this error . Anything I am missing here ?

RuntimeError: no validator found for <class 'datahub.ingestion.source.kafka_connect.KafkaConnectLineage'>, see `arbitrary_types_allowed` in Config

What version of python are you using?

python --version
Python 3.8.10

hmm so one thing that’s odd -

python --version

reports 3.8, but the paths in the traceback reference python 3.7
