dm_env: The DeepMind RL Environment API

This package describes an interface for Python reinforcement learning (RL) environments. It consists of the following core components:

• dm_env.Environment: An abstract base class for RL environments.
• dm_env.TimeStep: A container class representing the outputs of the environment on each time step (transition).
• dm_env.specs: A module containing primitives that are used to describe the format of the actions consumed by an environment, as well as the observations, rewards, and discounts it returns.
• dm_env.test_utils: Tools for testing whether concrete environment implementations conform to the dm_env.Environment interface.

Please see the documentation here for more information about the semantics of the environment interface and how to use it. The examples subdirectory also contains illustrative examples of RL environments implemented using the dm_env interface.
