This operation outputs "ref" after the update is done.
This makes it easier to chain operations that need to use the reset value.
Args
ref
A mutable Tensor. Must be one of the following types: float32, float64, int32, uint8, int16, int8, complex64, int64, qint8, quint8, qint32, bfloat16, uint16, complex128, half, uint32, uint64.
Should be from a Variable node.
value
A Tensor. Must have the same type 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.
