tf.contrib.framework.smart_case

Like tf.case, except attempts to statically evaluate predicates.

tf.contrib.framework.smart_case(
    pred_fn_pairs, default=None, exclusive=False, name='smart_case'
)

If any predicate in pred_fn_pairs is a bool or has a constant value, the associated callable will be called or omitted depending on its value. Otherwise this functions like tf.case.

Args
pred_fn_pairs	Dict or list of pairs of a boolean scalar tensor and a callable which returns a list of tensors.
default	Optional callable that returns a list of tensors.
exclusive	True iff at most one predicate is allowed to evaluate to True.
name	A name for this operation (optional).

Returns
The tensors returned by the first pair whose predicate evaluated to True, or those returned by default if none does.

Raises
TypeError	If pred_fn_pairs is not a list/dictionary.
TypeError	If pred_fn_pairs is a list but does not contain 2-tuples.
TypeError	If fns[i] is not callable for any i, or default is not callable.
