Module: tf.compat.v1.data.experimental Experimental API for building input pipelines. This module contains experimental Dataset sources and transformations that can be used in conjunction with the tf.data.Dataset API. Note that the tf.data.experimental API is not subject to the same backwards compatibility guarantees as tf.data, but we will provide deprecation advice in advance of removing existing functionality. See Importing Data for an overview. Modules service module: API for using the tf.data service. Classes class AutoShardPolicy: Represents the type of auto-sharding we enable. class CheckpointInputPipelineHook: Checkpoints input pipeline state every N steps or seconds. class CsvDataset: A Dataset comprising lines from one or more CSV files. class DatasetStructure: Type specification for tf.data.Dataset. class DistributeOptions: Represents options for distributed data processing. class MapVectorizationOptions: Represents options for the MapVectorization optimization. class OptimizationOptions: Represents options for dataset optimizations. class Optional: Represents a value that may or may not be present. class OptionalStructure: Type specification for tf.experimental.Optional. class RandomDataset: A Dataset of pseudorandom values. class Reducer: A reducer is used for reducing a set of elements. class SqlDataset: A Dataset consisting of the results from a SQL query. class StatsAggregator: A stateful resource that aggregates statistics from one or more iterators. class StatsOptions: Represents options for collecting dataset stats using StatsAggregator. class Structure: Specifies a TensorFlow value type. class TFRecordWriter: Writes a dataset to a TFRecord file. class ThreadingOptions: Represents options for dataset threading.
