I’m using the train function to run a Reinforcement Learning training using a PPO agent, with a rlSimulinkEnv object defining the environment.
Regarding the rlTrainingOptions, I’m using the default option for "SimulationStorageType", which is "memory". So I expect (if I understand correctly) that all the simulation data should be saved to RAM, not to disk, whenever possible. However I noticed that Simulink is actually saving the simulation data into .dmr files stored in my TEMPDIR.
I also tried to disable the Simulink logging to TEMPDIR directly from the Simulink Data Inspector, setting the Record Mode to "View during simulation only". However, as soon as I start the Reinforcement Learning Training, the simulation data are still saved as .dmr files in my TEMPDIR.
Is there a way to actually avoid saving .dmr files to TEMPDIR when training in a Simulink environment, and instead using only RAM to store the simulation data as long as the Matlab session is active?
