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
Public Methods
public Output <T> asOutput ()
Returns the symbolic handle of a 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 <Integer> 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
