This topic shows you how to manage Data Science Workshop (DSW) instances. You can start, stop, and delete DSW instances.

Prerequisites

  • If you want to manage DSW instances as a RAM user, you must first use your Alibaba Cloud account to authorize the RAM user. For more information, see Authorization.
  • A DSW instance is created. For more information, see Create instances.

Go to DSW

  1. Log on to the PAI console.
  2. In the left-side navigation pane, choose Model Training > DSW-Notebook Service.

Stop an instance

  1. Click DSW-Notebook Service.
  2. On the Notebook Models page, find the instance that you want to stop, and click Stop in the Actions column.
  3. In the dialog box that appears, select a stop method.
    You can use the following methods to support DSW instances:
    • Stop after Saving Environment: We recommend that you select this method if you have modified the default environment, for example, a software package or a pip package is installed.
    • Stop without Saving: Generally, you can select Stop without Saving if you do not modify the default environment.
    After the instance is stopped, the status in the Status column changes to Stopped. If the instance is a pay-as-you-go instance, the system stops charging you for the instance. Make sure that the status of the DSW instances that are not in use is Stopped. Otherwise, the system continues to charge you for the instances.

Start an instance

You can manually start an instance that is in the Stopped state.

  1. Click DSW-Notebook Service.
  2. On the Notebook Models page, find the instance that you want to start, and click Start in the Actions column.
    After the instance is started, the status in the Status column changes to Running. If the instance is a pay-as-you-go instance, the system starts to charge you for the instance. We recommend that you stop DSW instances after you complete model training. Otherwise, the system continues to charge you for the instances.

Delete an instance

You can delete instances that are not in use. After an instance is deleted, its data cannot be recovered.

  1. Click DSW-Notebook Service.
  2. On the Notebook Models page, find the instance that you want to delete, and click Delete in the Actions column.
  3. In the Delete message, click OK.
