Thank you very much!

I am using python3.7, tensorflow==1.15, stable-baselines==2.10.0, gym==0.18.0

PPO1 requires [OpenMPI]. If OpenMPI isn’t enabled, then PPO1 isn’t imported into the stable_baselines module. Please refer to the document, https://stable-baselines.readthedocs.io/en/master/modules/ppo1.html
