I do not have a recipe ready for using with org mode, and maybe you have 
already tried the following instruments:

1. Besides system-wide site-packages directory, there is similar ones 
for users, used by e.g. `pip install` (unless it is disabled accordingly 
to some recommendations).

2. It seems that *recommended* and more flexible way is per-project 
(per-version) virtual environments: venv in python3, similar thing were 
called virtualenv in python2: 
https://docs.python.org/3/tutorial/venv.html Maybe there is a convenient 
way to choose and switch venv's directly from emacs. In simple cases 
venv could be activated before starting emacs.

3. The Hitchhiker's Guide to Python have a couple of related sections. 
They might be a bit outdated but could be a source for convincing 
arguments to use venv's or for some usage patterns.
