I have some guesses - first I would try uninstalling (pip uninstall theano), and then let pymc3 specify the version (pip install --upgrade pymc3). You could also try conda uninstall theano, then conda install -c conda-forge pymc3 if you are using conda.

[StevenLi-DS]

I tried conda install -c anaconda libpython It seems works.

My vscode no longer works due to https://github.com/Microsoft/vscode-python/issues/5258 after I installed everything from conda forge. I will try and see if conda install will give me any issues.
