I meant why are you using an embedded application with a virtual environment? What sort of application do you have that requires users to configure a virtual environment, rather than providing its own set of libraries?

The embedding scenarios I'm aware of almost always want privacy/isolation from whatever a user has installed/configured, so that they can work reliably even when users modify other parts of their own system. I'm trying to understand what scenario (other than "I am an interactive Python shell") would want to automatically pick up the configuration rather than having its own configuration files/settings.
