tf.contrib.training.multiply_gradients(
grads_and_vars,
gradient_multipliers
)
Defined in tensorflow/contrib/training/python/training/training.py
.
Multiply specified gradients.
Args:
grads_and_vars
: A list of gradient to variable pairs (tuples).gradient_multipliers
: A map from eitherVariables
orVariable
op names to the coefficient by which the associated gradient should be scaled.
Returns:
The updated list of gradient to variable pairs.
Raises:
ValueError
: Ifgrads_and_vars
is not a list or ifgradient_multipliers
is empty or None or ifgradient_multipliers
is not a dictionary.
