Return either true_fn() if predicate pred is true else false_fn().

tf.contrib.framework.smart_cond(
    pred,
    true_fn=None,
    false_fn=None,
    name=None
)

If pred is a bool or has a constant value, we return either true_fn() or false_fn(), otherwise we use tf.cond to dynamically route to both.

Arguments:

  • pred: A scalar determining whether to return the result of true_fn or false_fn.
  • true_fn: The callable to be performed if pred is true.
  • false_fn: The callable to be performed if pred is false.
  • name: Optional name prefix when using tf.cond.

Returns:

Tensors returned by the call to either true_fn or false_fn.

Raises:

  • TypeError: If true_fn or false_fn is not callable.
