Ah, those are more recent than UHD 4.6. Is the environment variable XDG_DATA_HOME set on your system? What does "echo $XDG_DATA_HOME" print for you?
BTW, if the only problem is that the cal data path is misattributed, then you can set the environment variable UHD_CAL_DATA_PATH=~/.local/uhd/shrae/uhd/cal. That should do the trick. However, I would still like to figure out what caused this. --M On Mon, Apr 14, 2025 at 11:39 AM Tim Vancauwenbergh < tim.vancauwenberg...@gmail.com> wrote: > Hello Martin, > > only installed via apt, I did not specify snap. > uhd.get_lib_path() returns: /lib/x86_64-linux-gnu -> libuhd.so found here > uhd.get_pkg_path() returns: /lib > I am unable to use uhd.get_pkg_data_path() and uhd.get_module_paths() -> > uhd has no attribute > > Tim > > Op do 10 apr 2025 om 17:14 schreef Martin Braun <martin.br...@ettus.com>: > >> That was very helpful.
