Reinforcement Learning Episode Manager

After training has finished, If I close the "Reinforcement Learning Episode Manager" window, how do I reopen it ??

[Mike Croucher]

In MATLAB 2021a and above you can use the inspectTrainingResult function to do this as follows

trainingStats = train(agent,env,trainOpts);
inspectTrainingResult(trainingStats)

Hi Ahmad,

It is not possible to reopen the Episode Manager after closing it. The graphical window is triggered only when you run a function like train. The windows is destroyed once you close it. If you want to access specific training variables like EpisodeReward, TrainingSteps, you can get them in the workspace as output arguments.

Hope this helps.

To add to this answer, starting in R2020b, there is a method you can use to recreate the Episode Manager graph using the output arguments mentioned above

rlPlotTrainingResults(stats)

Thanks for the info! any news on when R2020b will roll out ?

Hello!

The following line doesn't work for me:

rlPlotTrainingResults(trainingStats)

I get the follwing error:

Unrecognized function or variable
'rlPlotTrainingResults'.

I would prefer using it instead of inspectTrainingResult() function, since I would like to plot it in a live script (and not open it in a new window).

Any Idea, please?
