Create a case operation. See also `tf.switch_case`. The `pred_fn_pairs` parameter is a dict or list of pairs of size N. Each pair contains a boolean scalar tensor and a python callable that creates the tensors to be returned if the boolean evaluates to True. `default` is a callable gener

         default=None,

         strict=False,
