Seemingly missing ipython module trying to use jupyter notebook with anaconda

问题

When opening a jupyter notebook, I get the following errors. Any idea how to fix this? I'm running on ubuntu 16.04 with Anaconda 2. Tried uninstalling and reinstalling ipython and tried doing that through both pip and conda. Didn't help.

Uninstalling Anaconda2 and installing Anaconda3 instead fixed this issue.
