Converts a fallback tensor to a bool 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

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.
