ModuleNotFoundError: No module named 'twilio'

Hi. Thought I would have a play with Twilio. Have installed Twilio. Copy and pasted one of their quickstart programs. In the program the from twilio.rest is underlined in red. So I ran anyway and got the Module Not Found Error. I am waiting for a reply on Github Twilio, but thought I would try here in case its an IDE conflict somehow.

In the terminal :

twilio --version

returns:

twilio-cli/2.0.1 win32-x64 node-v10.16.3

pip3 install twilio --upgrade

returns:
