It's apparently a linking issue:

patchelf --add-needed /lib/x86_64-linux-gnu/libudev.so.1 neoradio2.cpython-37m-x86_64-linux-gnu.so

Fixed it.

Maybe installing neoradio2 in a conda environment was the root cause of the issue?

Please try building from latest.

pip install git+https://github.com/intrepidcs/libneoradio2

@scollis Please note I haven't had time to officially test on a raspberry pi yet. I plan on getting to it after the conference is over and I'm back at home.

Thanks @drebbe-intrepid ! Let me know if you want a new issue opened narrowed to RPi. FYI I reinstalled the github code and still get the same error.

Yes please do, I don't have a raspberry pi with me on this trip so it will have to wait until I get home.
