Hi @yousef ahmed, welcome to Flyte. The error above suggests that you have a different data type passed to your code, i.e a numpy float value, but it instead expected a float value. Today, we don't support for numpy float values, hence an easy but not-so-efficient way would be to convert your numpy float values to floats. But remember this isn't the recommended way of doing things. We have numpy float support coming up soon!

fine, I'm new with Flyte. So, I followed the tutorial and this issue comes up!

Happy to help. Feel free to jump in for clarifications.

Which tutorial is it, @yousef ahmed?

the docs : https://docs.flyte.org/projects/cookbook/en/latest/auto/case_studies/feature_engineering/eda/index.html

@yousef ahmed could you please change the notebook at the end

from flytekitplugins.papermill import record_outputs
record_outputs(mae_score=mae_score)

from flytekitplugins.papermill import record_outputs
record_outputs(mae_score=float(mae_score)ç)

I tried this but didn't work, worked with me in other place "I think was notebook.py" but here not worked, in the end solved by help @Samhita Alla replace 'return mean(score) in cross_validate function to float(np.mean(score)).

Yeah this is ok

@yousef ahmed Exactly. You have converted the return type of mean(score) from being a numpy.float to a floating point type. I'm glad it worked!

yeah that worked for two notebooks also (supermarket_regression, supermarket_regression_2)
