HANA_ML PAL error - SAP DI (Trial edition)

100 Views Last edit Dec 14, 2020 at 02:43 PM 2 rev

My team is using SAP Data Intelligence (trial edition), we are working on house price prediction using HANA ML Training operator. We followed SAP Data Intelligence: Deploy your first HANA ML pipelines blog.

We are getting error in HANA_ML Training operator stating "Graph failure: operator.com.sap.ml.hana.training:hanamltraining1: Error while executing callback registered on port(s) ['trigger']: PAL is not installed" . We have installed "hana-ml==1.0.8" but it states PAL is not installed.

Please let me know how to fix this error.

FYI : We have deployed DI Trial edition in Google Cloud Platform.

I have attached screenshots of error message, HANA_ML Configuration and HANA_ML Script.

Error Message : (Output ports and respective input ports are properly connected)

HANA_ML operator configuration :

HANA_ML - Script Editor :

Kind regards,

Raevanth Kumar
