Python • Bookworm python lgpio module version question

I am running Bookworm on raspberry pi 4. When I run pip list for system-wide packages is see lgpio ver 0.2.2.0.

pi@desktop-pi:~ $ pip list | grep lgpio
lgpio 0.2.2.0
pi@desktop-pi:~ $

I then created a virtual environment called test3 and installed RPi.GPIO and gpiozero.

lgpio didn't get installed. So I ran pip install lgpio and got a different version

(test3) pi@desktop-pi:~ $ pip install lgpio

When I use gpiozero to define a button, I get this warning
(test3) pi@desktop-pi:~ $ python

When I look at devices.py, it is blank.

Why is lgpio in the virtual environment a different version than in the site wide environment? Any ideas?

Thanks
