class_docstr: The standalone sum metric.
  
  This utility metric is a general purpose metric that can be used to keep
  track of the sum of a sequence of values.
  
  Beware that this metric only supports summing numbers and the result is
  always a float value, even when `update` is called by passing `int` only.
