The In this work, we introduce Robust Gymnasium, a unified modular benchmark designed for robust RL that supports a wide variety of disruptions across all key RL components—agents’ In using Gymnasium environments with reinforcement learning code, a common problem observed is how time limits are incorrectly handled. For example, this previous blog used FrozenLake environment to test a TD-lerning method. Gymnasium's main feature is a set of abstractions that allow for wide interoperability between environments and training algorithms, making it easier for researchers to develop and test RL algorithms. Gymnasium is an open-source library providing an API for reinforcement learning environments. Introduction. The environment’s observation_space and action_space should have type Space[ObsType] and Space[ActType], see a space’s 0x00 前言. If you are running this in Google Colab, run: %%bash pip3 install gymnasium Training RL agents can be a noisy process, so restarting training can produce better results if convergence is not observed. Getting into reinforcement learning (RL), and making custom environments for your problems can be a daunting task. For more information, see Gymnasium’s Compatibility With Gym documentation. , 2016), the predecessor to Gymnasium, remains a widely used library in RL research.
