Get Notebook Differences
Important
Custom IAM policies that allow Amazon SageMaker Studio or Amazon SageMaker Studio Classic to create Amazon SageMaker resources must also grant permissions to add tags to those resources. The permission to add tags to resources is required because Studio and Studio Classic automatically tag any resources they create. If an IAM policy allows Studio and Studio Classic to create resources but does not allow tagging, "AccessDenied" errors can occur when trying to create resources. For more information, see Provide permissions for tagging SageMaker resources.
Amazon Managed Policies for Amazon SageMaker that give permissions to create SageMaker resources already include permissions to add tags while creating those resources.

As of November 30, 2023, the previous Amazon SageMaker Studio experience is now named Amazon SageMaker Studio Classic. The following section is specific to using the Studio Classic application. For information about using the updated Studio experience, see Amazon SageMaker Studio.
You can display the difference between the current notebook and the last checkpoint or the last Git commit using the Amazon SageMaker UI.
The following screenshot shows the menu from a Studio Classic notebook.
Get the Difference Between the Last Checkpoint
When you create a notebook, a hidden checkpoint file that matches the notebook is created. You can view changes between the notebook and the checkpoint file or revert the notebook to match the checkpoint file.
By default, a notebook is auto-saved every 120 seconds and also when you close the
notebook. However, the checkpoint file isn't updated to match the notebook. To save the
notebook and update the checkpoint file to match, you must choose the Save
notebook and create checkpoint icon (
) on the left of the notebook menu or use the Ctrl + S
keyboard shortcut.
To view the changes between the notebook and the checkpoint file, choose the
Checkpoint diff icon (
) in the center of the notebook menu.
To revert the notebook to the checkpoint file, from the main Studio Classic menu, choose File then Revert Notebook to Checkpoint.
Get the Difference Between the Last Commit
If a notebook is opened from a Git repository, you can view the difference between the notebook and the last Git commit.
To view the changes in the notebook from the last Git commit, choose the Git
diff icon (
) in the center of the notebook menu.
