Unable to use VIRGO, need guidance

[sirsendu64]

I installed GNU Companion, osmocom, and other dependencies. Installed Virgo also, as per the direction given in the manual. I'm using Linux Mint as OS. But could not understand how to import modules and where to import them. how to use it with GNU Companion? Please give me a step-by-step guide. Python 2.7.17 is there in my system. #python -c "import virgo" shows no output on the command line. virgo is present under module list.

Please wait a moment while I gather a list of all available modules...

Yes, python -m pip shows astro-virgo 3.8.1

Terminal Output as under:-

$ python -m pip list
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.

@sirsendu64 Firstly, why not use Python 3? Also, what happens if you run python -m pip show astro-virgo?

These three python are already installed

$ python3.10 --version
Python 3.10.0
$ python3 --version
Python 3.6.9
$ python --version
Python 2.7.17

Try installing/running with the other Pythons you've got installed. Python 2 is very outdated, with slightly different syntax, so Python 3.x is always more reliable. Check with pip list for the other Pythons and see if the GNU Radio module is recognized (that's probably the right Python version to use).

[sirsendu64]

My current GNU Companion version: GNU Radio Companion 3.8.3.1,
$python -m pip list
astro-virgo 3.8.1 ,
$ python -VV
Python 2.7.17 $ python3 -VV
Python 3.6.9 (default, Jun 29 2022, 11:45:57)
[GCC 8.4.0] ;
Now when I load grc wola or grc ftf file at GNU companion it shows red color error at observation.dat file.

Please help me out in this case and also tell me how to run those python files at Linux mint

I'm pretty sure your GNU Radio version uses Python 3 and not Python 2. Also regarding the flowcharts (which I guess aren't working properly because I haven't updated Virgo for GNU Radio 3.8).

@sirsendu64 In the meantime, to fix this double click on the dev_args and obs_file blocks and set the type to String. I'll try to push an update with the fix, give me an hour (but you can try this in the meantime, and recompile (button next to "play")). You do have to rename them back though and place them in the right folder.

Give me some time, if I can push an update it'll be easier to just update and not touch anything else.

@sirsendu64 Try updating virgo with pip install astro-virgo -U and check if it works with Python 3.
