Re: uhd.find_devices() - AttributeError

[Marcus Müller]

Hi Trung Trieu,

I can reproduce this, by running `podman run --rm -it ubuntu:22.04`, and in 
there

apt update; apt install -y gnuradio;
python3 -c 'from gnuradio import uhd;uhd.find_devices()'

so you're not alone!

The honest truth is that this line has been there since GNU Radio 3.4.2 , and as you can 
see, nobody remembered to remove it when it became dysfunctional. Oops!

For you, I'd have a workaround. Try this:

from gnuradio import uhd
from uhd import find as find_devices

find_devices("")

Best regards,
Marcus
