I learned the very hard way not to mess with the python version the system depends on.
If you absolutely must then build it separately and link (or use) that exactly like blender does with their binaries. Campbell (one of the core blender devs) used to love to bump the python version as soon as it was released and if you wanted to do any dev work you’d have to run another python environment until the distro version caught up. Being as I liked to use the fedora libs as a sort of sanity check this was a bit of a hassle to say the least.

That's not much of an issue on Nix. You can just override Python for your particular (machine learning) package set. The rest of the system will continue to use Python unmodified.
