I'm sorry you are running into issues here. would you please try
df = gl.SFrame.from_sql(session, "select * from apstats.radios limit 10", dbapi_module=cassandra)
df = gl.SFrame.from_sql(session, "select * from apstats.radios limit 10", dbapi_module=cassandra.cluster)
This may help us find the necessary connection object. Our
from_sql expects the database object to follow a particular standard, and it looks like it may not be the case for the cassandra package.
Let me know if that helps!
