after installing conda env: conda env create -f environment.yml , and cmake .. -DCMAKE_INSTALL_PREFIX=/home/ubuntu16-sdr2/anaconda3/envs/gr310/ in gr310 env
gnuradio 3.8.2.0 is still running:

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

lahc1 · 2022-09-01T12:47:59Z

Hi @tapparelj,
yes it seems a conda path problem, but I am not able to solve it.
I installed gnuradio 3.8.2 using conda.

any suggestions?

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.

tapparelj · 2022-09-06T13:52:22Z

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 ?

lahc1 · 2022-09-06T16:12:04Z

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.

tapparelj · 2022-09-07T07:28:57Z

Hi,
When you speak about the PC itself, just to be sure, its OS is Ubuntu?

lahc1 · 2022-09-07T07:32:34Z

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.

tapparelj · 2022-09-07T07:40:53Z

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

lahc1 · 2022-09-07T07:58:21Z

after setting the path to: export PATH=/home/ubuntu16-sdr2/anaconda3/envs/gr310/bin:$PATH
GNURadio is running but with version 3.8.2.

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

lahc1 · 2022-09-07T09:53:46Z

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:

(gr310) ubuntu16-sdr@ubuntu16sdr-OptiPlex-7070:~/Downloads/gr-lora_sdr/examples$ ./lora_TX.py 
[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.

tapparelj · 2022-09-07T12:51:41Z

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

lahc1 · 2022-09-07T13:33:38Z

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 ?

tapparelj · 2022-09-08T07:18:53Z

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.
