        i.e. server and clients are started in separate binaries independently.

    *   Example usage to create server: ```python server =
        tf.distribute.experimental.rpc.Server.create("grpc", "127.0.0.1:1234")
        @tf.function(input_signature=[ tf.TensorSpec([], tf.int32),

        tf.math.multiply(a, b)
