Github user agoodm commented on the issue: https://github.com/apache/zeppelin/pull/1632 To be honest, I don't see it being that big of a deal. Both profiles take about 5 minutes each which I think is fairly short, since up until recently we were spending 4 minutes just installing the R dependencies for all of the other profiles. Additionally, this would make it much easier to test everything for both python 2 and 3, which can be quite a pain to do manually with conda / virtualenv (eg, fiddling with the PATH before running tests for each case). Also, matplotlib and pandas are most likely used for a large percentage of python / pyspark use cases in Zeppelin, so I think having that integration tested would be really useful.
