Extracts the average gradient in the given ConditionalAccumulator.
The op blocks until sufficient (i.e., more than num_required) gradients have been accumulated. If the accumulator has already aggregated more than num_required gradients, it returns the average of the accumulated gradients. Also automatically increments the recorded global_step in the accumulator by 1, and resets the aggregate to 0.

Inherited Methods
Constants
public static final String OP_NAME
The name of this op, as known by TensorFlow core engine
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 ResourceAccumulatorTakeGradient<T> create (Scope scope, Operand<?> handle, Operand<TInt32> numRequired, Class<T> dtype)
Factory method to create a class wrapping a new ResourceAccumulatorTakeGradient operation.
Parameters
scope | current scope |
---|---|
handle | The handle to an accumulator. |
numRequired | Number of gradients required before we return an aggregate. |
dtype | The data type of accumulated gradients. Needs to correspond to the type of the accumulator. |
Returns
- a new instance of ResourceAccumulatorTakeGradient
