  1. Log in to the ModelArts console. In the navigation pane on the left, choose Development Workspace > Notebook.
  2. Start or stop the target notebook instance.
    • Starting a notebook instance

      2. In the displayed dialog box, select a JupyterLab version and set auto stop as required, and click OK.
    • Stopping a notebook instance

      Only running notebook instances can be stopped.

        After a notebook instance is stopped:

        • Data in the /home/ma-user/work directory and directories dynamically mounted to /data is saved. Data in other directories will be deleted. For example, the external dependency packages installed in other directories in the development environment will be deleted. Save your development environment settings as an image. For details, see Saving a Notebook Instance.
        • The notebook instance will no longer be billed. If the instance has an EVS disk attached, the storage space will still be billed.

  2. In the notebook list, locate the target notebook instance, and choose More > Delete in the Operation column. In the displayed dialog box, confirm the information, enter DELETE, and click OK.
