property name
class torch.monitor.Stat
Stat is used to compute summary statistics in a performant way over
   fixed intervals. Stat logs the statistics as an Event once every
   "window_size" duration. When the window closes the stats are logged
   via the event handlers as a "torch.monitor.Stat" event.
"window_size" should be set to something relatively high to avoid a
   huge number of events being logged. Ex: 60s. Stat uses millisecond
   precision.
If "max_samples" is set, the stat will cap the number of samples
   per window by discarding add calls once "max_samples" adds have
   occurred. If it's not set, all "add" calls during the window will
