On Ubuntu 22.04, packages are usually installed at /usr/lib/python3.12. This allows for packages to access them. However, ROS 2 Jazzy runs natively on Ubuntu 24.04 (Noble Numbat), it strictly enforces [PEP 668 (Marking Python base environments as "externally managed")](https://peps.python.org/pep-0668/)
This results in packages unable to locate these dependencies and break (mostly vision and filters). An approach to use “break-system-packages” is suggested on an [OpenRobotics forum](https://discourse.openrobotics.org/t/rosdep-for-pip-is-broken-on-jazzy/38981).
Behavior: Packages can't be accessed at runtime. When run pip freeze can see that package is installed
When trying to reinstall package, can see that package is already installed in /opt/venv/ instead of /usr/lib/

When installing packages, the build logs shows that packages are installed successfully.
Extra: shapely and scikit-learn missing from uav environment, causing crashing of pose estimator and filters in UAV. Can consider adding them in pip list or apt list.
