Functions
CreateDataDescriptor(...): Constructs a DataDescriptor instance targeting a tff.DataBackend.
deserialize_computation(...): Deserializes 'tff.Computation' as a pb.Computation.
deserialize_value(...): Deserializes a value (of any type) from executor_pb2.Value.
get_context_stack(...): Returns the context stack.
local_cpp_executor_factory(...): Returns an execution context backed by C++ runtime.
merge_cardinalities(...): Merges dicts existing and to_add, checking for conflicts.
serialize_computation(...): Serializes 'tff.Computation' as a pb.Computation.
serialize_value(...): Serializes a value into executor_pb2.Value.
set_default_context(...): Places ctx at the bottom of the stack.
to_call_dominant(...): Transforms local (non-federated) computations into call-dominant form.
transform_postorder(...): Traverses comp recursively postorder and replaces its constituents.
transform_preorder(...): Walks the AST of comp preorder, calling transform on the way down.
unique_name_generator(...): Yields a new unique name that does not exist in comp.
