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](https://us1.discourse-cdn.com/flex002/uploads/python1/original/3X/8/0/80458f6cf06a55b1cebb05d5e5b698549498c768.png) 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
