DistributedVariable

Abstract Value Members

abstract val distributionType: Type

Type of this distributed variable (e.g., per-device or mirrored).
abstract def get(device: String = "current")(implicit context: DistributionContext): variables.Variable

Returns the value on the specified device (defaults to the current device, if not provided.
abstract val index: Map[DeviceSpecification, variables.Variable]

Index map from devices to variables.
abstract val primaryVariable: variables.Variable

Primary variable.

Creates an op that reads the value of this variable sparsely, using the provided indices.
Creates an op that reads the value of this variable sparsely, using the provided indices.
This method should be used when there are multiple reads, or when it is desirable to read the value only after some condition is true.
indices
Indices to use for the sparse read.
name
Name for the created op.
returns
Created op.

def initializedValue(implicit context: DistributionContext): Output

Value of the initialized variable.

Value of the initialized variable. You should use this instead of the variable itself to initialize another variable with a value that depends on the value of this variable.

Example:

// Initialize `v` with random values, and then use `initializedValue` to guarantee that `v` has been initialized
// before its value is used to initialize `w`. The random tensor will only be sampled once.
val v = tf.variable("v", FLOAT32, Shape(10, 40), tf.RandomTruncatedNormalInitializer())
val w = tf.variable("w", initializer = tf.ConstantInitializer(v.initializedValue * 2.0))

val initializer: Op

Returns the initializer for this variable.
val isInitialized: Output

Op output that is true when the variable has been initialized and false otherwise.

def op(implicit context: DistributionContext): Op

Returns the op of this variable.
def read(name: String = "Read")(implicit context: DistributionContext): Output

Creates an op that reads the value of this variable.
Creates an op that reads the value of this variable.
This method should be used when there are multiple reads, or when it is desirable to read the value only after some condition is true.
The returned value may be different from that of value depending on the device being used, the control dependencies, etc.
returns
Created op.

def toProto(exportScope: String): VariableDef

Alias for toVariableDef.

Convert this object to its corresponding ProtoBuf object.
exportScope
Optional string specifying the name scope to remove. Only the ops within this name scope will be included in the resulting ProtoBuf object and the export scope will be stripped from their names to allow for easy import into new name scopes.
returns
ProtoBuf object corresponding to this object.
def value(implicit context: DistributionContext): Output

Returns a cached op which reads the last value of this partitioned variable.
Returns a cached op which reads the last value of this partitioned variable.
You can not assign a new value to the returned tensor as it is not a reference to the variable.
The returned op output will not inherit the control dependencies from the scope where the value is used, which is equivalent behavior to that of getting the value of a variable.
NOTE: You usually do not need to call this method directly, as all ops that use variables do so by internally converting them to tensors.
