Reference runtime environment? python + tensorflow/pytorch

Is there a reference runtime environment for RLlib? Like a reproducible one from auto testing. I’m trying to isolate a problem and seems to be difference between between Ray version and tensorflow/pytorch. Having known working cases would help a lot.

Edit: to elaborate, I have code written in Ray 1.4 but doesn’t run in Ray 1.6 or 1.7. Unfortunately, I couldn’t reproduce the same runtime I had in 1.4.
