I can't "import keyring", so either that's a module that isn't in the
Python standard library, or "keyring" is some object you've
instantiated. My crystal ball says this might be something to do with
Amazon Web Services, but it's hard to be sure. Can you please help us
out here by telling us all the dependencies of your code, and also
showing us a complete runnable program?
