Unrecognized property 'LearningFrequency' for class 'rl.option​.rlPPOAgen​tOptions'.

2 views (last 30 days)
Hello everbody,
I'm facing the following error:
Unrecognized property 'LearningFrequency' for class 'rl.option.rlPPOAgentOptions'.
It occurs when I enter the following at the command line:
agent.AgentOptions.LearningFrequency=4;
'agent' has been defined before, as a PPO agent, and I'm using R2023b.
Did I miss something about this hyperparameter?
Thanks in advance for your help!
Nicolas

Hi Nicolas,
The error you get is due to the fact that the LearningFrequency property in the rlPPOAgentOptions class was introduced in MATLAB R2024a release. You can check the version history of the class(or any other function) in the Version History section of the documentation page: https://www.mathworks.com/help/reinforcement-learning/ref/rl.option.rlppoagentoptions.html#mw_abe4fee0-4021-4936-a3a1-5bc7c8e85cbc
Also, you can refer the release notes for R2024a for all the new updates to the Reinforcement Learning Toolbox here: https://www.mathworks.com/help/reinforcement-learning/release-notes.html
