Create and use a PAI Studio node - DataWorks - Alibaba Cloud Documentation Center

Machine learning nodes are used to call tasks that are created in Platform for AI (PAI) and schedule production activities based on the node configurations.

Prerequisites

A machine learning experiment is created in PAI.

In this topic, a heart disease prediction experiment is used to describe how to load a machine learning experiment to a machine learning node in DataWorks. For more information about how to create a machine learning experiment, see Predict heart disease.

Procedure

Go to the DataStudio page.
Log on to the DataWorks console. In the left-side navigation pane, choose Data Modeling and Development > DataStudio. On the page that appears, select the desired workspace from the drop-down list and click Go to DataStudio.
On the DataStudio page, move the pointer over the icon and choose Create Node > Machine Learning > Machine Learning Platform for AI.
In the Create Node dialog box, configure the Path and Name parameters.
Click Confirm.
On the configuration tab of the node, select a machine learning experiment that you created from the Experiment drop-down list.
If you want to modify the experiment, click Edit in PAI Console to go to the experiment editing page in the PAI console.
Note
You can select a machine learning experiment from the Experiment drop-down list and modify the experiment on the experiment editing page in the PAI console only after you create a machine learning experiment in the PAI console. If the Experiment drop-down list is left empty, you need to go to the PAI console from the DataStudio page and create a machine learning experiment in the PAI console. To go to the PAI console from the DataStudio page, perform the following steps: Click the icon in the upper-left corner of the DataStudio page and choose All Products > Machine Learning > PAI.
On the configuration tab of the node, click Properties in the right-side navigation pane. On the Properties tab, configure scheduling properties for the node. For more information, see Overview.
Save and commit the node.
Important
You must configure the Rerun and Parent Nodes parameters on the Properties tab before you commit the node.
1. Click the icon in the top toolbar to save the node.
2. Click the icon in the top toolbar.
3. In the Submit dialog box, configure the Change description parameter.
4. Click Confirm.
If the workspace that you use is in standard mode, you must click Deploy in the upper-right corner of the configuration tab to deploy the node after you commit it. For more information, see Deploy nodes.
Perform O&M operations on the node. For more information, see Perform basic O&M operations on auto triggered nodes.
