Hello @lahc1,
It seems the some paths to the older version of gnuradio are still remaining after the activation of the new conda environment. Can you answer to the following questions:
- How did you installed gnuradio 3.8.2? with conda, pybombs, apt, from source, or any other way?
- While in the environment gr310
- Do the result
conda list | grep "gnuradio"only mention versions 3.10.3.0? - What is the result of
gnuradio-config-info -v --prefix? - What is the result of
echo $PATH
- Do the result
from gr-lora_sdr.

Hi @tapparelj,
yes it seems a conda path problem, but I am not able to solve it.

Hi,
It seems that there is an issue with the overall installation if you can't launch gnuradio-companion. Can you try duplicating the conda environment again and when building the lora_sdr module, do not specify the prefix (it will install in the current conda environment if any is active)?

Hi, I have done this but still stuck with same issues. I even deleted all the environment then install again and still stuck. any recommendation? thanks
gnuradio 3.8.2 is working fine in a separate conda environment.

Hi,
The argument 0 of Gtk.StyleContext.add_provider_for_screen( is uspposed to be your screen.
- Do you have a peculiar setup for your display?
- What is the output of
echo $DISPLAY?- if there is not output can you try to run
export DISPLAY=:0?
- if there is not output can you try to run

hi,
that is not an issue, terminal is trying to launch Xming. I tried it also on the PC itself and got same output of Gnuradio.

Hi,
When you speak about the PC itself, just to be sure, its OS is Ubuntu?
from gr-lora_sdr.
lahc1
commented on August 9, 2024
yes, it is Ubuntu 18.
could it be that the base or other conda environments are conflicting with gr310 env?
because on base and one other env GNURadio 3.8.2 is installed.

Can you try to set the path /home/ubuntu16-sdr2/anaconda3/envs/gr310/bin in the very beginning of $PATH to be sure it uses those binaries first?
export PATH=/home/ubuntu16-sdr2/anaconda3/envs/gr310/bin:$PATH

Do you have anything in echo $PYTHONPATH and echo $LD_LIBRARY_PATH ?
If not you can try to set them
export PYTHONPATH=/home/ubuntu16-sdr2/anaconda3/envs/gr310/lib/python3.10/dist-packages:$PYTHONPATH
and
export LD_LIBRARY_PATH=/home/ubuntu16-sdr2/anaconda3/envs/gr310/lib:$LD_LIBRARY_PATH

I already set echo $PYTHONPATH and echo $LD_LIBRARY_PATH as you mentioned. It is still not working.

I have another problem with UHD, it got updated to version 4.2.0. But the version I need is 3.15 because the USRPs are also flashed with UHD3.15:

[INFO] [UHD] linux; GNU C++ version 10.3.0; Boost_107400; UHD_4.2.0.HEAD-release

any suggestion how to switch back to UHD3.15?
thanks.

Can't you just conda remove uhd and conda install -c conda-forge uhd=3.15 ?

commented on August 9, 2024
it worked, now I have UHD 3.15.0. But uhd_usrp_sink is missing from GNURadio. I tried sudo ldconfig, it didn't help.
is there any way to make UHD 3.15 compatible with GNURadio 3.10.3 ?

commented on August 9, 2024
Hi,
is gnuradio-uhd still listed by conda list | grep "gnuradio" ? If not you can try to install it with conda install gnuradio-uhd and see if it tries to override your UHD installation. Else you might try to build gr-uhd from source (https://github.com/gnuradio/gnuradio/tree/main/gr-uhd).
In any case, I'm not aware of which version of UHD is compatible or not with gnuradio 3.10 but reflashing your USRP might be the easiest way to go.
