upgrade pybind11 to a version >=2.12.0

Numpy 2 introduced binary incompatibility with respect to numpy 1.. This breaks my code which relies on pybind11.
The latest version of pybind11 promises to fix that such that modules will work with both numpy 1 and 2.
Would be nice to see this improvement arrive for the ROS2 community.
Thanks!

Thanks for the report! The vendor package tracks the version of python3-pybind11 in Ubuntu. It looks like the next ubuntu LTS release will have a version greater than 2.12.0. I would expect ROS L-turtle will be the first with pybind11 >= 2.12.0 because ROS Kilted still targets Ubuntu Noble.

What is the recommended way for me to work around this?
Thanks!

I assume if you're using numpy 2 you probably installed it with pip. If you're using Ubuntu, I'd recommend using using the system package python3-numpy which is still verison 1.
