- If True, the subtraction will be protected by a lock;
otherwise the behavior is undefined, but may exhibit less contention.public Output<T> asOutput()
Operand
Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.
