Re: Problem with 3.10.12.0

Marcus,

I upgraded to GNU Radio 3.10.12.0.

Python 3.13.5 came along with it.

I am using Debian 13 (Trixie) on my RPi.

I used sudo apt install.

I hope this is enough info to help.

Jim

Hey Jim,
don't know how you've installed Pybind and your Python! As said, it looks
like your update
of Python happened without the other libraries, and here, Pybind, getting
rebuilt/updated
as well. I don't know your operating systems and installation methods, so
it's impossible
for me to advise!

Best,
Marcus
