changing autocommit

Hello guyz, 
    I am having a trouble with autocommit, the problem is: 
    I want that autocommit be alway on. Then i did a function called 
    atomic_start, that turn autocommit off and make the next commands a 
    transaction, so when i call atmic_commit, it commits,
    self.connection.commit. But i see that i cant change autocommit after i
    have activate a cursor, see: 

    AttributeError: Can't change autocommit when a cursor is active.

    Any suggestion?

Cheers,
