Solve the following python programming problem given the following code:
def install_cache(cache_name = 'cache', backend = None, expire_after = None, allowable_codes = (200,), allowable_methods = ('GET',), session_factory = CachedSession, **backend_options) : 
    '
    Installs cache for all ``Requests`` requests by monkey-patching ``Session``

    Parameters are the same as in :class:`CachedSession`. Additional parameters:

    :param session_factory: Session factory. It must be class which inherits :class:`CachedSession` (default)
    ' 
    if backend : 
        backend = backends.create_backend (backend, allowable_codes, backend_options) 
class _ConfiguredCachedSession (session_factory) : 
        def __init__(self) : 
            super (_ConfiguredCachedSession, self).__init__ (cache_name = cache_name, backend = backend, expire_after = expire_after, allowable_codes = allowable_codes, allowable_methods = allowable_methods, ** backend_options) 
_patch_session_factory (_ConfiguredCachedSession) 

    
    

    Fix the buggy line: backend = backends.create_backend (backend, allowable_codes, backend_options)

#Here is Python program to fix the buggy line: backend = backends.

backend = backends.create_backend (backend, cache_name, backend_options)
