Config documentation

[an3252sv]

Hi!
Where can I find the documentation for all config parameters that the method get_cfg() returns?
This page https://detectron2.readthedocs.io/en/latest/modules/config.html#yaml-config-references lists a lot of parameters, but they don't correspond to the output from get_cfg().

The method get_cfg() returns the following:

Maybe you could start with the configs in a specific model https://github.com/facebookresearch/detectron2/tree/main/configs

[an3252sv]

Thanks for your reply, but I could not find any documentation under configs, only config-files.

[zhanghang1989]

I usually read through the code directly, for example:

https://github.com/facebookresearch/detectron2/blob/main/detectron2/modeling/meta_arch/rcnn.py#L77
