So I am confused because it says that ipython prerequisites are meet but still
fails to start iphython interpreter
So what is involved in the process to start ipython interpreter from zeppelin
point of view?

It might be due other reason, you can set the interpreter log level to be DEBUG
to get more info.
Add following into log4j.properties
log4j.logger.org.apache.zeppelin.interpreter=DEBUG

Based on the error message, you are still using python instead of ipython. It
is hard to tell what's wrong.
One suggestion is to try 0.8.2 which is the latest release.

Try this
%pyspark
%matplotlib inline
import matplotlib.pyplot as plt
plt.figure()
plt.plot([1, 2, 3])

Another example:
%pyspark
import matplotlib.pyplot as plt
plt.plot([1, 2, 3])
z.show(plt)
plt.close()
<module 'matplotlib.pyplot' from
'/home/mansop/anaconda2/lib/python2.7/site-packages/matplotlib/pyplot.pyc'>
According to documentation
https://zeppelin.apache.org/docs/0.8.0/interpreter/python.html#matplotlib-integration
Am I right assuming that I can use z.show in %pyspark?
Thank you

Subject: can't plot
Dear Zeppelin user community,
I am running Zeppelin 0.8.0 and I am not able to print a plot using pyspark
interpreter:
This is my notebook:
%pyspark
import matplotlib.pyplot as plt
plt.figure()
plt.plot([1, 2, 3])
And this is the output:
[<matplotlib.lines.Line2D object at 0x7fd34321c450>]
Any idea?
