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 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.
