I saw the session on pre-installing the libraries.. 

--https://www.databricks.com/dataaisummit/session/goodbye-cluster-wait-time-hello-lightning-fast-rpy...

I implemented the steps to create a python file in "root/.ipython/profile_default/startup/" and that is executing fine and adding the path in sys.path.

But still import fails on libraries. 

If I do append in sys.path specifically in notebook that works. Can someone help me out in resolving this issue.
