ref by adding
value to it.
tf.assign_add( ref, value, use_locking=None, name=None )
This operation outputs "ref" after the update is done.
This makes it easier to chain operations that need to use the reset value.
tf.math.add, this op does not broadcast.
value must have
the same shape.
ref: A mutable
Tensor. Must be one of the following types:
half. Should be from a
Tensor. Must have the same shape and dtype as
ref. The value to be added to the variable.
use_locking: An optional
bool. Defaults to
False. If True, the addition will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention.
name: A name for the operation (optional).
Same as "ref". Returned as a convenience for operations that want to use the new value after the variable has been updated.
