Tried last commit.
I installed jupyter, IPython, ipykernel, grpcio in my conda environment and
i configured my python interpreter like

And then i'm getting `No module named py4j.java_gateway` error on first
`%python.ipython` execution

And second execution, `z` is not available.

Looks like py4j library is not in python path. @zjffdu Do you have any idea
on this?
