First try uninstalling pip from your system explicitly. Note that when you were attempting to upgrade pip, it was already attempting to do so (from trace above):

attempted_uninstalling_pip

Here, were just going to do it explicitly.

First try:

  1. pip uninstall pip

if that doesn’t work:

  1. Try uninstalling pip manually from its current location. On my Windows based system, it is located here: C:\users\your_username\AppData\Local\pip

Then re-install pip
