is there a particular reason why you want to use your own environment instead the one that comes with Houdini?

you can install python 3 in the pc,
use houdini python2 to run a python3 as a subprocess,
the python 3 can do the tensorflow and the python2 is just a runner

os.popen.subprocess(“python3 file.py -args….”)

or a vm with linux and put houdini, python, tensorflow etc… all the stuff you need, not something that i think is a great idea since the VM use a lot of Ram, that you might end up needing for houdini process.

this are just quick ideas that came to my mind.

what is the thing you required with python3 that you cant do with python2? if is any library, you can just import it to your python script, beside print() using parenthesis everything else is an internal change, (mostly working range that will become generators instead lists)

when you install python already comes with pip / easy install,
