Web: This is because in gymnasium, a single video frame is generated at each call of env.step (action). However, in highway-env, the policy typically runs at a low-level frequency (e.g. 1 Hz) so that a long action ( e.g. change lane) actually corresponds to several (typically, 15) simulation frames. WebPPO policy loss vs. value function loss. I have been training PPO from SB3 lately on a custom environment. I am not having good results yet, and while looking at the tensorboard graphs, I observed that the loss graph looks exactly like the value function loss. It turned out that the policy loss is way smaller than the value function loss. the play on one
