Plugin: Julia | Dataiku

SofiaPedraza

Hi, I had installed the plugin in DataIku to create and execute Julia recipes the same way you would use any other code recipes. It makes that a Julia kernel also becomes available for Jupyter notebooks.

I am using the Dataiku dataset reading package, where it doesn't seem to recognize entered datasets. The code used is:

using Dataiku, DataFrames
import Dataiku: get_dataframe

df = get_dataframe(dataset"PROJECTKEY.myDataset")

It ran into this error

UndefVarError: isnothing not defined

Can you please let me know on how I can overcome this issue ?

Thank you in advance for your return,

Best regards.

Hi @SofiaPedraza
,

Could you confirm the version of Julia that you have installed?

julia -v

You may want to try updating Julia to the latest (or a more recent version), stop DSS, then from the DSS data directory rerun the Julia integration using the below command:

./bin/dssadmin install-julia-integration
