Module: tf.contrib.eager

TensorFlow Eager execution prototype.

EXPERIMENTAL: APIs here are unstable and likely to change without notice.

To use, at program startup, call tf.compat.v1.enable_eager_execution().

Modules

metrics module: Metrics namespace.

Classes

class Checkpoint: Groups trackable objects, saving and restoring them.

class Checkpointable: Manages dependencies on other objects.

class EagerVariableStore: Wrapper allowing functional layers to be used with eager execution.

class ExecutionCallback: Valid callback actions.

class GradientTape: Record operations for automatic differentiation.

class Iterator: An iterator producing tf.Tensor objects from a tf.data.Dataset.

class Network: Represents the composition of a set of Layers.

class Saver: A tf.compat.v1.train.Saver adapter for use when eager execution is enabled.

class Sequential: Represents a linear sequence of Layers or functions.

class TensorSpec: Describes a tf.Tensor.

class Variable: Variable based on resource handles.

Functions
