```
This happens because Zeppelin refers to
`matplotlib.rcParams['savefig.format']`
https://github.com/apache/zeppelin/blob/master/interpreter/lib/python/mpl_config.py#L83
which is only present in matplotlib 1.2.0
(https://github.com/matplotlib/matplotlib/blob/v1.2.0/matplotlibrc.template#L355)
and onwards.
### What type of PR is it?

* [ZEPPELIN-2827](https://issues.apache.org/jira/browse/ZEPPELIN-2827)
