tf.nest.flatten( structure, expand_composites=False )
If nest is not a sequence, tuple (or a namedtuple), dict, or an attrs class, then returns a single-element list: [nest].
In the case of dict instances, the sequence consists of the values, sorted by key to ensure deterministic behavior. This is true also for OrderedDict instances: their sequence order is ignored, the sorting order of keys is used instead. The same convention is followed in pack_sequence_as. This correctly repacks dicts and OrderedDicts after they have been flattened, and also allows flattening an OrderedDict and then repacking it back using a corresponding plain dict, or vice-versa. Dictionaries with non-sortable keys cannot be flattened.
Users must not modify any collections used in nest while this function is running.
