matlab crashes when trying to train deep re-inforcement learning

[Afshin Samani]

Hi,

I setup a customized environment for reinforcement learning based on a simple model I had constructed in opensim.
I made a matlab file attached to this query to use the reinforcement learning toolbox made available in matlab.
When I try to train the agent, matlab consistently crashes and no error massages is generated so I have no idea what to fix.
I see the first data point in the training plot and then crash stops the progress of the training.
I attached my model in opensim and the code I used to setting up the environment and training it.

Here are the matlab crash files:

Could anyone try and see if you reproduce the same error? if so, any suggestion for fixing the problem?

Best regards,
Afshin
