Converts a tensor to a scalar predicate.
tf.raw_ops.ToBool(
input, name=None
)
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.
