Cannot replicate a LGBM model

Fidan

Hi, I have trained a LGBM model with visual ML and now I am trying to replicate this model in a local environment using the parameters estimated through model training. I cannot get the identical probabilities. Is it somehow possible to locally replicate a model built on Dataiku?

Hi Fidan,

I hope that you are doing well.

Would you mind providing some more context here. Have you exported your trained model or are you attempting to recreate the model locally manually?

You can export the trained model following our doc:

https://doc.dataiku.com/dss/latest/machine-learning/models-export.html#export-to-python

You have multiple options outlined above which will cover your usecase. This will allow you to best match the pattern you see in visual ML

Note that the generated notebook from jupyter notebook model export process is for educational and explanatory purposes only. In particular, this notebook does not reproduce all preprocessing capabilities of DSS, and is only a best-effort approximation of the model trained in DSS.

(see: https://doc.dataiku.com/dss/latest/machine-learning/models-export.html#export-to-jupyter-notebook )

If you are already taking this route and exporting the model this will be the closest you could get to the behavior seen on visual ML.

Let me know if you have any further questions or inquiries here.

Best,

Yasmine
