The Gym interface is simple, pythonic, and capable of representing general RL problems: import gym env = gym . Encapsulate this function with the Compute the render frames as specified by render_mode attribute during initialization of the environment. The render modes are still exposed by using the class variable render_modes which can be set to an empty array by the Gym base class. When I attempt to test the environment I get the TypeError: reset() got an unexpected keyword argument 'seed'. register_envs (gymnasium_robotics) env = gym.
