RL agent error using simulink

i got this error anyone has idea what is the problem ?

• 'C:\Program Files\MATLAB\R2020a\toolbox\rl\rl\simulink\+rl\+simulink\+blocks\AgentWrapper.m' at line 154
• 'C:\Program Files\MATLAB\R2020a\toolbox\rl\rl\simulink\+rl\+simulink\+blocks\AgentWrapper.m' at line 203

• Undefined function 'getActionInfo' for input arguments of type 'double'.

this occurs when i run simulation on the simulink using RLagent and i create envirnoment (Model Workspace)

老哥，你问题解决了吗？（如果解决了，怎么弄的？）

如果没解决，你的matlab版本是不是低了，换成2021a试一下，我在2021a中可以成功运行这个车-杆仿真了。

Looks like when you call getActionInfo, instead of passing an environment or agent object as an argument, you are passing a double.

Please refer to this page for examples.
