module 'dataikuapi' has no attribute 'DSSClient' when trying to connect from outside DSS python

AttributeError: module 'dataikuapi' has no attribute 'DSSClient'

using the above code im trying to simply test connecting to DSS instance from python.

Python is on my local PC and DSS is on AWS.

Installed libraries dataiku-internal-client.tar.gz and dataiku-api-client.

However get error

import dataikuapi

host = "https://hereisurl"
apiKey = "hereiskey"

client = dataikuapi.DSSClient(host, apiKey)

Gone through all guides and cant fathom out what im doing wrong!

TIA
