tf.contrib.training.multiply_gradients
Multiply specified gradients.
tf.contrib.training.multiply_gradients(
grads_and_vars, gradient_multipliers
)
| Args |
|---|
grads_and_vars | A list of gradient to variable pairs (tuples). |
gradient_multipliers | A map from either Variables or Variable op names to the coefficient by which the associated gradient should be scaled. |
| Returns |
|---|
| The updated list of gradient to variable pairs. |
| Raises |
|---|
ValueError | If grads_and_vars is not a list or if gradient_multipliers is empty or None or if gradient_multipliers is not a dictionary. |
