Hi!  
I want to optimize the hyper-parameter of my projects.  
How to apply Bayesian optimization to RL?  
Is automatic parameter tuning possible?

Hey @Xim_Lee , could you ask this question on the “tune” forum here? Ray comes with a library called “Tune” and it’s actually recommended to run all RLlib workloads via tune. And yes, tune offers different hyperparameter search algos, including Bayes-opt. 🙂
