matlab 中运行时出现错误使用 rlPredefinedEnv (line 74)

Question

rlPredefinedEnv requires a keyword for the environment type.

%% 读取环境
mdl = 'rlCartPoleSimscapeModel';
open_system(mdl)
env = rlPredefinedEnv('CartPoleSimscapeModel-Continuous');
obsInfo = getObservationInfo(env);
numObservations = obsInfo.Dimension(1);
actInfo = getActionInfo(env);

Answer 1

以下Keyword都是可选的：

Predefined keyword representing the environment name, specified as one of the following:

MATLAB Environment

'BasicGridWorld'

'CartPole-Discrete'

'CartPole-Continuous'

'DoubleIntegrator-Discrete'

'DoubleIntegrator-Continuous'

'SimplePendulumWithImage-Discrete'

'SimplePendulumWithImage-Continuous'

'WaterFallGridWorld-Stochastic'

'WaterFallGridWorld-Deterministic'

Simulink Environment

'SimplePendulumModel-Discrete'

'SimplePendulumModel-Continuous'

'CartPoleSimscapeModel-Discrete'

'CartPoleSimscapeModel-Continuous'

上述代码在我的电脑上能正常打开模型，我的软件版本为2020b，如下
