Python script using the spark library at Bluemix

I am trying to write python script to call spark library at Bluemix platform. Would you mind advise the flow?

I have created Apache Spark Analytic Service at Bluemix, and open a iPython Notebook. However, I can't install new python package using !pip install <package>

And suppose I have solved this issue, I would like that it works like an application that I can make it continuously at background. Is it possible?

Also, you can do it another way:

First find home dir: print os.environ["HOME"] Then install module to this directory: !pip install <package> -t 'your home directory'

Append path to directory:

 import sys, os

Finally import module: import <package>
