Using the Machine Learning Libraries in SAP HANA Cloud

Chief partner engineer, Philip MUGGLESTONE just updated his SAP HANA Cloud playlist on the SAP HANA Academy YouTube channel with a new video covering the machine learning libraries native to SAP HANA Cloud

  • PAL  – Predictive Analysis Library
  • APL – Automated Predictive Library

In this blog, you will find the video embedded with some additional information and resources.

You can watch the video tutorial in just under 12 minutes. What you get back is

  • Understand the prerequisites
  • Getting started with PAL
  • Getting started with APL

For those less familiar with the machine learning libraries: PAL is a native (built-in) application function library (AFL) for SAP HANA. APL bundles the algorithms of SAP Predictive Analytics which goes back to KXEN InfiniteInsight, acquired by SAP in 2013. Both AFLs can be used for linear regression and other common algorithms.

To continue your machine learning journey on SAP HANA Cloud, the following blog post is highly recommended:

Prerequisites

As with the SAP HANA platform edition (on-premises), we need to enable the script server process. Currently, this currently requires a service request on component HAN-CLS-HC (as documented). In addition, we need to create an SAP HANA Cloud instance with a minimum of 3 vCPUs. Scaling an existing SAP HANA Cloud instance up from 2 to 3 vCPUs currently also requires a service request and this can be combined.

The SAP HANA Cloud trial instance is fixed a 2 vCPUs and does not support AFLs (time of writing).

      Great intro Denis, note the ScriptServer can now be enabled with the Cloud Platform Cockpit UI.

      Thanks, Christophe!

      For the reader,

      Self-service to enable the scriptserver service for PAL is available as of the QRC 03 release. As this requires 3 virtual CPUs, this is currently not available for the trial environment

      Hi Denys,

       

      Is there any plan to provide scriptserver activation for hana cloud trial instances?, as you said it's necessary to execute pal, apl, flowgraphs...

      Thanks.

      Regards.

      Jorge Porca.

      Hi Jorge,

      I have not seen any information indicating that a 3 vPCU configuration for SAP HANA Cloud will be made avaiable anytime soon but these things can change of course.

      You can follow the SAP HANA Cloud tag (blogs and Q&A) for the latest updates. Should this be made avialable there will be announcements, for sure.

      Thanks for your response Denis,

      Trial instances already have the option for 3 vCPU since Cristhmas aprox., so I hope that scriptserver option will be available soon.

      In the meanwhile I will follow your advice about the SAP HANA Cloud tag.

      Kind Regards.

      Jorge.

      Hi Denys, you are right. I have checked with a new trial account.

      Thanks.
