WebJul 4, 2024 · After some amount of training on a custom Multi-agent environment using RLlib's (1.4.0) PPO network, I found that my continuous actions turn into nan (explodes?) which is probably caused by a bad gradient update which in turn depends on the loss/objective function.. As I understand it, PPO's loss function relies on three terms: WebMar 13, 2024 · 1 Answer. If your action space is continuous, entropy can be negative, because differential entropy can be negative. Ideally, you want the entropy to be decreasing slowly and smoothly over the course of training, as the agent trades exploration in favor of exploitation. With regards to the vf_* metrics, it's helpful to know what they mean. raakaruokosokeri
