Pip does not work after upgrade to ubuntu-16.10

Question

Running a command alongwith pip gives the following error. Even the command pip -V produces the following error.
I read that the error is due to setuptoo

Answer 1

Upgrade your setuptools: wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python3

Generally sudo combined with pip is considered harmful, avoid this when your system is not already broken.
