Seemingly Impossible Install Conditions For Tensorflow and Stable-Baselines OpenAI

I’m trying to use OpenAI stable-baselines. This requires python 3.5 or higher. I set up my virtual environment etc., installed all dependencies. No problem. Then I try running a test script and it turns out that stable-baselines does not support Tensorflow 2. I need Tensorflow 1.15. No problem. I try to install tensorflow 1.15, but can’t because it is not available in pip anymore, for python3. Ok, so I need python 2.7 to use tensorflow 1.15… but then I can’t use stable-baselines, because it needs python 3… Help!
