gym version:0.21.0 一、保存模型 当前我们需要训练的代码如下: importgymfromstable_baselines3importPPOenv=gym.make('LunarLander-v2')env.reset()model=PPO('MlpPolicy',env,verbose=1)model.learn(total_timesteps=100000) 我们将训练步数降低为 10000 步,同时创建保存模型及日志的目录文件夹: importosmodels_...

一、stable-baselines3库是干什么的 Stable Baselines3 (SB3) is a set of reliable implementations of reinforcement learning algorithms in PyTorch. It is the next major version of Stable Baselines. 二、为什么要用公共库 简单,方便 三、stable-baselines3简单实例 importgymfromstable_baselines3importPPOfroms...
AssertionError: The algorithm only supports (<class 'gym.spaces.discrete.Discrete',) as action spaces but Discrete(5) was provided My question is the following: does Stable Baselines3 support Gymnasium? I have tried to instead use gym.spaces in order to define the action_space and observation...
