I was trying to run this example:
https://www.mathworks.com/help/robotics/ug/avoid-obstacles-using-reinforcement-learning-for-mobile-robots.html
and I am running with the following error after random of episodes. For example the following error occures after 173 successfull episode:
Error using rl.train.SeriesTrainer/run
An error occurred while running the simulation for model 'exampleHelperAvoidObstaclesMobileRobot' with the following RL agent blocks:
