iteration_statistics.IterationStatistics

Class IterationStatistics

A class for storing iteration-specific metrics.

The internal format is as follows: we maintain a mapping from keys to lists.
Each list contains all the values corresponding to the given key.

For example, self.data_lists[‘train_episode_returns’] might contain the
per-episode returns achieved during this iteration.

Attributes:

• data_lists: dict mapping each metric_name (str) to a list of said
  metric across episodes.

Methods

__init__()

append

append(data_pairs)

Args:

• data_pairs: A dictionary of key-value pairs to be recorded.
