//"""Update 'ref' by adding 'value' to it.

//

// 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`, `int64`, `int32`, `uint8`, `uint16`, `int16`,

// `int8`, `complex64`, `complex128`, `qint8`, `quint8`, `qint32`, `half`.

// 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.

// name: A name for the operation (optional).

//

// Returns:

// Same as "ref". Returned as a convenience for operations that want

// to use the new value after the variable has been updated.
