Description

I thought the setup_id is unique for each flow + parameter configuration?

With https://www.openml.org/api/v1/xml/setup/list/setup/1 I would expect that I get only one single hyperparameter configuration that refers to one single flow. However, there are many different flows listed.

Also https://www.openml.org/api/v1/xml/setup/list/flow/56 gives me hyperparameter configurations for many different flows? Although I requested only the setups for flow 56.

Did something change? Because I think this issue did not appear some time ago.

Research direction

Start by comparing the responses from /api/v1/xml/setup/list/setup/1 and /api/v1/xml/setup/list/flow/56, then trace how setup_id and flow filters are handled. Done means each endpoint returns only the setup configurations matching the requested setup or flow, with the observed behavior clarified or corrected.
