Google Cloud vision API: "Request had insufficient authentication scopes."

[Rali Tsanova via StackOverflow]

Hi I'm trying to use google's cloud vision API, specifically this example: https://cloud.google.com/vision/docs/label-tutorial#label_tutorial_1

I followed this tutorial: https://cloud.google.com/vision/docs/getting-started#set_up_a_service_account for setting up a service account but when I run my code I get: googleapiclient.errors.HttpError: https://vision.googleapis.com/$discovery/rest?version=v1 returned "Request had insufficient authentication scopes.">

Can anybody help? I can't figure out what's going on, my code is 1:1 with the tutorials.
