Module: tff.framework

Libraries for extending the TensorFlow Federated core library.


class CachingExecutor: The caching executor only performs caching.

class CardinalityCarrying: Asbtract interface for objects that carry information about cardinality.

class ComputationBuildingBlock: The abstract base class for abstractions in the TFF's internal language.

class Context: Represents the interface to the context that the API executes against.

class ContextStack: An interface to a context stack for the API to run against.

class DataBackend: Abstract interface for data backends.

class DataExecutor: The data executor is responsible for the data building block.

class EagerTFExecutor: The eager executor only runs TensorFlow, synchronously, in eager mode.

class ExecutionContext: Represents an execution context backed by an executor_base.Executor.

class Executor: Represents the abstract interface that all executors must implement.

class ExecutorFactory: Interface defining executor factories.

class ExecutorService: A wrapper around a target executor that makes it into a gRPC service.

class ExecutorValue: Represents the abstract interface for values embedded within executors.

class FederatedComposingStrategy: A strategy for composing federated types and intrinsics in disjoint scopes.

class Ingestable: Abstract interface for objects able to ingest themselves in an executor.

class ReferenceResolvingExecutor: The lambda executor handles lambda expressions and related abstractions.

class RemoteExecutor: The remote executor is a local proxy for a remote executor instance.

class ResourceManagingExecutorFactory: Implementation of executor factory holding an executor per cardinality.

class SizeInfo: Structure for size information from SizingExecutorFactory.get_size_info().

class SizingExecutorFactory: A executor factory holding an executor per cardinality.

class TFParser: Callable taking subset of TFF AST constructs to CompiledComputations.

class ThreadDelegatingExecutor: The concurrent executor delegates work to a separate thread.

class TransformingExecutor: This executor transforms computations prior to executing them.
