Refreshing your Workspace

If you need to start from scratch, fetch the latest version of the notebook (reset the notebook), encounter an error that you can't recover from, or run into a 404 error, follow these steps:

1. Open the Notebook in the Lesson.
2. Access the File View: Once the notebook opens, click File → Open to open your workspace file browser.
3. Shut Down the Notebook: In the workspace, tick the checkbox next to your notebook file to select it. Then, click Shutdown. The icon next to the filename will change from green to gray, indicating that the notebook has been shut down.
4. Create a Backup: Select the notebook file again by ticking its checkbox, then click Duplicate. When prompted, enter a new filename that is different from the original. For example: C1M1_Assignment.ipynb (original) → C1M1_Assignment_v2.ipynb (Note: The actual notebook name will vary depending on the course.)
5. (Optional) Manage Other Files: If there are other files (such as datasets) you want to restore or refresh, tick their checkboxes. You may choose to Delete them for a fresh copy, or Duplicate/Download them individually if you wish to keep a backup before deleting.
6. Restore the Original Notebook: Find the file named C1M1_Assignment_original.ipynb (or similarly named, depending on your notebook). Select it by ticking its checkbox, then click Duplicate and confirm by clicking Yes. A new file, such as C1M1_Assignment-Copy1.ipynb, will be created. Rename this file to C1M1_Assignment.ipynb to restore the original notebook.
7. Refresh the Lesson: Return to the lesson page and refresh your browser. You should now see the latest, restored version of your notebook.
