Yes, that's what I said: I had to run it in a virtual environment. So
it's what I said, the official way of using python for a developer is to
use it in a virtual environment. Which means the programmer is expecting
to install the library required by is software and not using the
libraries of the system. It's not my decision, it's, like I said, the
new way: the libraries installed by the system are used by the system
and the libraries installed by the developer are used by the software.
They are not shared anymore and it avoids compatibilities issues.

And it's exactly what snap, appimage and flatpack are doing on a broader
way than python. Like it or not, it's what people are doing now, and
there are reasons behind that.
