I have installed Anaconda3-4.4.0 on Ubuntu 16.04. I can't find any variation of virtualenv, PATH hacking, or modifications to kernel.json, that stops it from using /usr/bin/python3 when creating a new notebook. I want it to use the anaconda installed version exclusively so I can have different versions of packages in the anaconda environment. I have removed my ~/.jupyter and ~/.ipython. I have tried virtual environments and everything I can think of.
What do I have to do to get it prevent it from using the system installed version of python3.
