InputRejected: Importing set_benchmark from zipline.api raised an ImportError. No modules or attributes with a similar name were found. Last warning! One more import error and your account will be suspended for security reasons until a human can talk to you.  

(N.B. I'm happy to talk to a human about why I'm trying to use your documented functions in your environment. /snark)

Without it I simply get a "set_benchmark" global name not found.
