Check out this tutorial demonstrating Python interoperability in Swift.
This function is intended to set the Python version before any references to the global PythonInterface called Python -
it cannot be used to switch Python versions dynamically.

A good way to get a taste of Swift for Tensorflow language and tools is to set it up with Jupyter with the fastai Swift notebooks. I wanted a quick setup, which the Mac install experience currently not, so instead I installed the release binaries in a Ubuntu container via Docker. The setup process for this scenario is not well documented, so here it is for you / future me.
What we're about to do is install the S4TF 0.4 release and the fastai v3 Swift notebooks on Ubuntu 18.04. Generally we follow the swift-jupyter docker file, but install cpu-only release versions of the packages.
Below are some of the references I looked at:
