tf.contrib.framework.smart_case(
pred_fn_pairs,
default=None,
exclusive=False,
name='smart_case'
)
Defined in tensorflow/python/framework/smart_cond.py
.
Like tf.case, except attempts to statically evaluate predicates.
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 toTrue
.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
: Ifpred_fn_pairs
is not a list/dictionary.TypeError
: Ifpred_fn_pairs
is a list but does not contain 2-tuples.TypeError
: Iffns[i]
is not callable for any i, ordefault
is not callable.
