PPO/SAC Baselines for MetaDrive

Hello everyone, I’m working on a research problem for which I need single agent ppo/sac Baselines to compare against. From my own research I could only find implementations on multi agents or safe RL envs. Also the metadrive’s own implementation is just importing already existing weights and not training which just has ppo. Is there any implementation Baselines for me to compare against, maybe from some paper which I can refer to. Any help would be appreciated! Thanks.
