class_docstr: Interface for defining the components of an offline RL agent.
  
  Implementations of this interface contain a complete specification of a
  concrete offline RL agent. An instance of this class can be used to build an
  offline RL agent that operates either locally or in a distributed setup.

docstr: Create an actor instance to be used for evaluation.
  
  Args:
