Assuming you want to access the cloud vision API locally since on App Engine it should "just work".

To authenticate using a service account JSON keyfile you need to point to it using an environment variable:

$ export GOOGLE_APPLICATION_CREDENTIALS="/path/to/keyfile.json"

You can also authenticate using the Google Cloud SDK if it's available

$ gcloud beta auth application-default login
