        This method wraps the provided summary in an `Event` protocol buffer
        and adds it to the event file.
        You can pass the result of evaluating any summary op, using
        [`Session.run()`](client.md#Session.run) or
        [`Tensor.eval()`](framework.md#Tensor.eval), to this
        function. Alternatively, you can pass a `tf.Summary` protocol
        buffer that you populate with your own data. The latter is
        commonly done to report evaluation results in event files.
        Args:
          summary: A `Summary` protocol buffer, optionally serialized as a string.
          global_step: Number. Optional global step value to record with the
            summary.
