Re: Import error using an OOT

[Cinaed Simson]

Opps - ft8_qso.conf is not a yaml file - it's just a  nonexcutable data 
file which the python code parses.

No I'm not.

The ft8_qso.conf.is a data input file - or a yaml file - it is read by 
the python code.

If there's a problem with the python code, the application will crash 
and burn regardless of the content of ft8_qso.conf.

If you change the the top line in the file

  run_response.py code

from

  #!/usr/bin/env python

to

  #!/usr/bin/env python3

it should work.

You are confusing main() in run_response.py with the ‘main’ section 
in ft8_qso.conf.
parser.get in line 36 is looking for the ‘main’ section but throws 
the NoSectionError.
Why can’t the parser see the ‘main’ section?
When I said I have run an OOT before, I meant another OOT which runs 
well in this same app. However, this is irrelevant since we are not 
talking about the same problem.

The main method is defined beginning on line 216 and called 4 times 
on lines 36-39.

And it appears the configparser is throwing the NoSectionError.

Try commenting out line 36 to see if line 37 throws the same exception.

When you said is has run before, did it run under python3.9?

I have attached the 2 files in question. Look at the beginning of 
run_response.py. It uses ConfigParser to access the ft8_qso.conf 
configuration file.
This line seems to be the problem: my_call = str(parser.get('main', 
'my_call_sign')).
But ‘main’ is a section in the ft8_qso.conf file. Why can’t it find 
‘main’?

The problem appears to be in the python code

  response.py

- there is no 'main()' method.

Type

and see if it works.

I have developed and used an OOT before without an issue. I looked 
at the previous OOT and reviewed the GNU Radio docs on OOTs 
without seeing anything different.
I am using Python 3.92 with GNU radio 3.9.4.0 on a Raspberry Pi.
I hope someone can show me the error of my ways.
