variable interpolation failing on diffrerent structure

[sebastian-bearing]

good morning, i was wondering some help if posible on understanding why these is not working, i have the following project structure

 ├── config/
 │   ├── parsers/
 │   │   ├── parser_1.yaml
 │   │   └── ....
 │   ├── config_1.yaml
 │   └── ....
 ├── common_steps.py
 ├── main.py
 └──  utils.py

some snip of the code:

config_1

---
defaults:
    - _self_
    - /parsers/parser_1
parameters:
    algo: 7

parser_1

---
_target_: utils.make_pipeline
_recursive_: False
steps_config:
  - load:
      _target_: common_steps.F1
  - transform:
      _target_: common_steps.F2
      algo: ${parameters.algo}

main

@hydra.main(version_base="1.1", config_path="config", config_name=end_settings)
def my_app(cfg: DictConfig) -> None:
    print(OmegaConf.to_yaml(cfg))
my_app()

the end result of outputs/../../.hydra/config.yaml is:

parameters:
  algo: 7
parsers:
  _target_: utils.make_pipeline
  _recursive_: false
  steps_config:
  - load:
      _target_: common_steps.F1
  - transform:
      _target_: common_steps.F2
      algo: ${parameters.algo}

i don't get why the ${parameters.algo} is not overriding mi desire output is:

parameters:
  algo: 7
parsers:
  _target_: utils.make_pipeline
  _recursive_: false
  steps_config:
  - load:
      _target_: common_steps.F1
  - transform:
      _target_: common_steps.F2
      algo: 7

thanks in advance and i really appreciate any help

Not sure I understand the problem, is it just that you should add resolve=True when calling to_yaml()?

thanks a lot i was not aware these parameter

OmegaConf interpolations are evaluated on access. When you convert to yaml, by default the interpolation "pointer" is preserved.
