Hello everyone ! I have some question regarding kedro pipeline for forecasting solution. is there a way to run kedro sub-pipeline inside a loop so that it generates the forecast. catch output of one iteration is input for other iteration. Please let me know.

Not really, since that would violate the requirement that the Kedro pipeline is a DAG. I'd perhaps use an orchestrator (e.g. Prefect, Airflow, Kubeflow Pipelines, whatever) to orchestrate modular subpipelines if want looping functionality.

inst there any way in kedro to do that ?

Not really? A Kedro pipeline must be a DAG. You can dynamically construct unrolled loops, but it's not really a supported use case/isn't ideal for many reasons (but you can see https://github.com/kedro-org/kedro/issues/1993 and other related issues).

Would it be possible to not loop the node but to put the loop inside the node?

that is doable. but i wont be able to visualize the process
