Ok,
One more question, I am getting an error when I force ipython
%mansop.ipyspark
print("Hello world!")

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
Manuel

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?
