Re: Import error using an OOT

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

then enter

  import ft8

and see if it works.

I have created an OOT which when I incorporate it in my flowgraph shows the following error:

 

Failed to evaluate import expression 'import ft8'

 

The yaml file is:

 

id: ft8_run_response

label: ft8

category: '[ft8]'

 

templates:

  imports: import ft8

  make: ft8.run_response(${ft8_button})

  callbacks:

  - set_ft8(${ft8_button})

 

#  Make one 'parameters' list entry for every parameter you want settable from the GUI.

#     * label (label shown in the GUI)

#     * dtype (e.g. int, float, complex, byte, short, xxx_vector, ...)

#     * default

parameters:

- id: ft8_button

  label: ft8_button

  dtype: raw

  default: 0

 

#  'file_format' specifies the version of the GRC yml format used in the file

#  and should usually not be changed.

file_format: 1

 

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.
