class_docstr: Writes protocol buffers to event files to be consumed by TensorBoard.
  
  The `FileWriter` class provides a mechanism to create an event file in a
  given directory and add summaries and events to it. The class updates the
  file contents asynchronously. This allows a training program to call methods
  to add data to the file directly from the training loop, without slowing down
  training.

docstr: Reopens the EventFileWriter.
  
  Can be called after `close()` to add more events in the same directory.
  The events will go into a new events file.
  Does nothing if the EventFileWriter was not closed.
