The "dataiku" module is an internal one, which is designed to work while within DSS. Note that DSS already includes Jupyter notebook, so you don't need to have an external Jupyter.
If you want to control DSS from an external system, you can use the public API and its Python client (the "dataikuapi" package). See http://doc.dataiku.com/dss/4.0/api/public/client-python/
Do you know if the internal module works when writing a plugin? I am trying to use the dataiku module in the development of a plugin and am getting the following error:
File "/dataiku-dss-4.0.7/python/dataiku/__init__.py", line 85, in api_client [2017/09/21-15:24:10.746] [Exec-4512] [INFO] [dku.utils] - raise Exception("API Ticket not available") [2017/09/21-15:24:10.746] [Exec-4512] [INFO] [dku.utils] - Exception: API Ticket not available
