title: Cannon uninstall pip3, but pip3 --version shows it is existing
body: <p>I installed conda and pip, also i have pip3. I installed jupyter notebook with pip, but when i started with jupyter notebook, i didnt have some packages, so i decided to uninstall pip and use jupyter from conda, because jupyter and terminal command 'python' didn't see some packages, that did have conda </p>
  
  <p>i used:
  pip uninstall pip</p>
  
  <p>but nothing changes, 'python' and jupyter notebook is still working as he worked before
  i tried to do pip3 uninstall pip3, but it says "Cannot uninstall requirement pip3, not installed"</p>
  
  <p>Help me, please, how do i delete pip at all from Linux Mint?</p>
  
  <p>pip3 --version shows "pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.6)"</p>
  
  <p>pip3 list also works</p>
  
  <p>Maybe question is really stupid, but i`m new to programming, so i really don't understand, how it works, so hoping to your understanding.
  Thanks</p>
