How to change setting for object which is inside another obejct?

[dvstter]

I have solved this problem in another not so quite beautiful method. So my question is that is there any more formal method?

my directory is like this:

--config
    |-cfg.yaml
    --encoder
        |-resnet50.yaml
        |-resnet151.yaml

Any resnet50/151.yaml just like this:

_target_: xxx.Resnet
parameter1: 10

And in my cfg.yaml, I have this:

defaults：
    - encoder: resnet50
agent:
    _target_: xxx.xxxAgent
    encoder: ${encoder}

Yeah, I defined the encoder object in the global vision, then I quoted this object in agent object's field. In fact I only need that appears in the agent object's field. So is there any better or more formal method to resolve this?

I have recently started using Hydra and I am pretty interested in this pattern. As a starting idea, I would create the following folder tree

config
| - cfg.yaml
| - agent
    | - default.yaml
    | - encoder
        | - resnet50.yaml
        | - resnet151.yaml

default.yaml contains

defaults:
  - encoder: null
_target__: xxx.xxxAgent

if you need the encoder name, you may define a field in resnet50.yaml or resnet151.yaml
