Cannot import tensorflow in IPyhon3 - python-3.x

Question

I am just pasting the output of my bash shell which could be quite explicit. Running IPython:
petrux#orion:~/Projects/dket$ ipython
Python 3.5.2 (default, Nov 17 2016, 17:05:23)
Type 'copyright', 'credits' or 'license' for more information
IPython 6.0.0 -- An enhanced Interactive Python. Type '?' for help.

I am running Ubuntu 16.04 as OS.
Thanks in advance.
