Could a dataset be an input to another dataset ?
Yeah… I know… Strange question. 😅
Let me clarify:
I need to load and “manipulate” the pickle of a model “tagged” as ‘Production’ by MLFlow. (i.e this is therefore not for serving, in which case I could have used mlflow serving cli)
In order to so, I first need to query MLFlow’s tracking db to get the source / path of that model.
So, to rephrase my initial question
Could a pandas.SQLQueryDataSet (the model source / path) become an input to a pickle.PickleDataSet (the mode itself)
Or am I framing / approaching the problem from a wrong angle ?
Many thanks in advance
Regards

Effectively you can implement sth like a “lazy dataset”.
You can have a custom DataSet which in it’s
load Copy code
class LazyDataSet(AbstractDataSet):
# constructors and other stuff
def _load():
def lazy_loader(path):
return PickleDataSet(path).load()
return lazy_loadernode(inputs="from_sql_query", func=<extract the path you need>, outputs="path_you_need")node(inputs=["path_you_need", "lazy_dataset"], lambda path, lazy: lazy(path))marrrcin

Thx a lot @marrrcin
(though I must confess that I’m a bit jealous that I can’t, for now, come up with such solutions by myself 😜 )
Thx again 🙏🏼
