ToBool

public final class ToBool

Converts a tensor to a scalar predicate.

Converts a tensor to a scalar predicate with the following rules:

- For 0D tensors, truthiness is determined by comparing against a "zero" value. For numerical types it is the obvious zero. For strings it is the empty string.

- For >0D tensors, truthiness is determined by looking at the number of elements. If has zero elements, then the result is false. Otherwise the result is true.

This matches the behavior of If and While for determining if a tensor counts as true/false for a branch condition.

Inherited Methods

Public Methods

public Output <Boolean> 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 ToBool create ( Scope scope, Operand <T> input)

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

Parameters
scope current scope
Returns
  • a new instance of ToBool

public Output <Boolean> output ()
