Building on OpenAI Gym, Gymnasium enhances interoperability between environments and algorithms, providing tools for customization, reproducibility, and robustness. Due to its easiness of use, Gym has been widely adopted as one the main APIs for environment interaction in RL and control. According to the documentation, calling env. import gymnasium as gym # Initialise the environment env = gym. We will be concerned with a subset of gym-examples that looks like this: In OpenAI Gym <v26, it contains “TimeLimit. If you are running this in Google Colab, run: import gymnasium as Train Gymnasium (formerly OpenAI Gym) Reinforcement Learning environments using Q-Learning, Deep Q-Learning, and other algorithms. VectorEnv), are only well OpenAI’s Gym or it’s successor Gymnasium, is an open source Python library utilised for the development of Reinforcement Learning (RL) Algorithms. The Gym interface is simple, pythonic, and capable of representing general RL problems: Gymnasium is an open source Python library for developing and comparing reinforcement learning algorithms by providing a standard API to communicate between learning algorithms and environments, as well as a standard set of environments compliant with that API. The environments can be either simulators or real world systems (such as robots or games). make Gym is a standard API for reinforcement learning, and a diverse collection of reference environments#. 19. Many publicly available implementations are based on the older Gym releases and may not work directly with the Gym is a standard API for reinforcement learning, and a diverse collection of reference environments#.
