tf.contrib.framework.smart_case
Stay organized with collections

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.
