I am on a Jetson nano, and I need to run ROS humble under a version of Python more recent than the 3.8 version in Ubuntu 20.04's APT repo. As such, I installed python 3.11.6 through pyenv, and built ROS2 humble from source. When I run my ros package (built with ament_python), however, my python scripts execute with the system's native python 3.8, even though pyenv still shows 3.11.6 as active, and if I run "python3" in the terminal, I get a 3.11.6 cli.

What is the best way of rectifying this? Is there a way to specify that a particular Python interpreter should be used?

Thanks!

I assume I will have to re-build from source, because ros2 seems to have built with python 3.8 for some packages, and 3.11 for others- when I do so, should I completely remove the native python3.8? Is that even safe to do on a Jetson nano?

Thanks!
