Hello,

I seem to have encountered the same issue here, I am wondering how you resolved this issue? Thank you very much!

I am using python3.7, tensorflow==1.15, stable-baselines==2.10.0, gym==0.18.0 /usr/local/lib/python3.7/site-packages/sklearn/utils/validation.py:37: DeprecationWarning: distutils Version classes are deprecated. Use packaging.version instead. LARGE_SPARSE_SUPPORTED = LooseVersion(scipy_version) >= '0.14.0' WARNING: Logging before flag parsing goes to stderr.

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
