Variable

public final class Variable

Holds state in the form of a tensor that persists across steps.

Outputs a ref to the tensor state so it may be read or modified. TODO(zhifengc/mrry): Adds a pointer to a more detail document about sharing states in tensorflow.

Nested Classes

class Variable.Options Optional attributes for Variable

Constants

String OP_NAME The name of this op, as known by TensorFlow core engine

Inherited Methods

Constants

public static final String OP_NAME

The name of this op, as known by TensorFlow core engine

Constant Value: "VariableV2"

Public Methods

public Output <T> asOutput ()

Returns the symbolic handle of the tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

public static Variable.Options container (String container)

Parameters
container If non-empty, this variable is placed in the given container. Otherwise, a default container is used.

public static Variable <T> create ( Scope scope, Shape shape, Class<T> dtype, Options... options)

Factory method to create a class wrapping a new Variable operation.

Parameters
scope current scope
shape The shape of the variable tensor.
dtype The type of elements in the variable tensor.
options carries optional attributes values
Returns
  • a new instance of Variable

public Output <T> ref ()

A reference to the variable tensor.

public static Variable.Options sharedName (String sharedName)

Parameters
sharedName If non-empty, this variable is named in the given bucket with this shared_name. Otherwise, the node name is used instead.
