Hey all, This can be done in catalog.yml to access data through namespace, how can I do this in parameters.yml???

"{namespace}.data_fro":
    type: xyz
    filepath: "path/to/data/{namespace}/month.csv"

This feature is newly added with the purpose to simplify

catalog.yml

which is often huge and verbose. How do you want to use it for parameters?

I have parameters defined which I want to use in every pipeline they are static. If I give namespace to my pipelines, it automatically gets added to params:namespace.model.

If you want to use the same parameters in every pipeline then use

from kedro.pipeline.modular_pipeline import pipeline
pipeline(
   parameters={"params:model_options": "params:model_options"},
   #... rest of the args
)

Keys in dict are names of the parameters within the “namespaced” piepline, values are parameters “from root” = parameters.yml

Agree with @marrrcin, it seems like you just want to escape from the namespace

@marrrcin works like a charm, but why does it work??

The

parameters=

in the modular pipeline’s constructor maps the parameters from the “un-namespaced” ones to the “namespaced” ones

Nice thank you so much

You can also have things like:

parameters={"params:name_that_you_use_in_the_namespaced_pipeline": "params:other_name"},

This is exactly how the args for pipeline works. I guess the symmetry of the arguments between node and pipeline is confusing because they are doing different thing. How can we improve this docs to make it clearer? https://docs.kedro.org/en/stable/nodes_and_pipelines/modular_pipelines.html#using-the-modular-pipeline-wrapper-to-provide-overrides
