Run a recipe from a scenerio

Erlebacher

I am writing a recipe to retrain a custom model created in a Python recipe. This recipe creates a pickle file that contains the model, which is then read by a downstream model that performs predictions. I know how to build a dataset from a scenario, but a pickle file is not a dataset. How can I force the recipe that creates the model to run? Thanks.

Hi @Erlebacher
,

Our approach in this situation is to write the pickle file to a DSS Folder and then build the Folder (which is one of the Build options).

Hi @Erlebacher

Scenarios can also build models. If you add a "Build / Train" step to your scenario, there will be an option to choose a model to build:

This should run the recipe that creates the model.

Be sure to set the Build mode to "Build only this dataset" or "Force-rebuild dataset and dependencies" if you want the model to be built every time the scenario is run.

Thanks,

Hi @ZachM
,

When you say `model`, are you referring to a model as defined by Dataiku, created through the lab interface? I simply have a Python recipe that creates a model that is saved in a pickle file. I solved the problem by creating a Dataset with the contents ('Successful update', along with date/time). I have the scenario clear the data set and run it. This works fine.

Hi @Erlebacher

Sorry, I was talking about a Dataiku model. I didn't realize you were using a Python recipe.

Your solution sounds good!

Thanks,
