Grant the permissions that are required to use iTAG - Platform For AI

The first time you use iTAG of Machine Learning Platform for AI (PAI), you must grant the Object Storage Service (OSS) access permissions to the service-linked role of iTAG. iTAG provides personnel roles for labeling operations, such as administrator, labeling team leader, or labeling worker. You can assign relevant roles to the RAM users you use to manage operation permissions. This topic describes how to grant permissions to an operation account, the permissions of the three labeling roles, and how to assign these roles to a RAM user.

Authorize the operation account

iTAG is an intelligent data labeling platform that supports multiple data types, such as image, text, video, and audio, as well as multimodal labeling. You may need to activate and authorize the following cloud services when you use iTAG.

PAI module: iTAG

Log on to the PAI console.
On the Workspace Details page of the workspace, add a RAM user as a member of the workspace. For more information, see Manage the members of a workspace.
When you add a RAM user as a workspace member, select a workspace role for the RAM user based on the iTAG role that you want to assign to the RAM user. The following table describes the mappings between the two types of roles.
