I tried what you said at the windows command prompt. It went through some stuff and said " you are using pip version 8.1.2, however 9.0.1 is available. You should consider upgrading via the 'python - m pip install --upgrade pip' command.

I thought that was what I just did. -- but it apparently did not work
