Hello all,
I've been having some issues with gnuradio 3.10 and still haven't
figured it out yet. I'd really appreciate it if anyone could help me
or have any pointers that I can follow.
For your reference, I have an Ubuntu 22 virtual machine running on
VMware and installed gnuradio (as well as other dependencies) from the
instructions at https://wiki.gnuradio.org/index.php/InstallingGR (I
tried both installation methods via apt and via ppa but no luck).
The error message I have is:
-----------------------------------------------------------------
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3/dist-packages/gnuradio/uhd/__init__.py", line
73, in find_devices
return __builtins__['map'](to_pythonized_dev_addr,
uhd_python.find_devices_raw(*args, **kwargs))
AttributeError: module 'gnuradio.uhd.uhd_python' has no attribute
'find_devices_raw'. Did you mean: 'find_devices'?
-----------------------------------------------------------------
Steps to reproduce:
1. Install gnuradio 3.10
2. From the command line, launch python3 by typing "python3"
- >>> from gnuradio import uhd
- >>> print(uhd.find_devices())
That's where the error occurs.
The content of
'/usr/lib/python3/dist-packages/gnuradio/uhd/__init__.py' can also be
found at

Note that I don't have this issue with Ubuntu 20, which uses
gruradio 3.8 and SWIG instead of PyBind11. So instead of 'uhd_python',
it'll be 'uhd_swig' from the above error message. The code with
gnuradio 3.8 can also be found at
https://github.com/gnuradio/gnuradio/blob/maint-3.8/gr-uhd/python/uhd/__init__.py
Thank you all in advance!!

Ubuntu 20 has a much-older version of Gnu Radio AND a much-older (3.15)
version of UHD.
Near as I can tell, gr-uhd doesn't expose find_devices() in gr-uhd,
which is a wrapper for UHD specifically for Gnu Radio.
