Hi,
I am getting an error “UNQ_C1” wasn’t found in code after I make my submission with all tests passing. As a first, I think I deleted too much from the notebook and would like to restart with the original notebook but cannot seem to get there. I think that I maybe should not have deleted anything outside the areas for the code to be updated. I realized this later. Is there a way to reset the notebook back to the original?
thanks,
Ryan
Hi Ryan, welcome to the community!
To return to a checkpoint, click on File and select Revert to Checkpoint.
Hope this helps!
In case you do not have a previous checkpoint, you’ll have to delete your notebook (via the File->Open menu), and then use “Get latest version” from the Lab Help menu (the question-mark inside a circle). This will give you a fresh copy so you can start over.
in your first grade cell where you write codes, it usually has header as UNQ_C1 which you have probably deleted. add it and submit.
but in case you have edited more than that, then you will have to get fresh copy and re-do assignment and write codes only between assigned markers ###START AND END CODE HERE###
Do not edit, delete or add anything outside these markers
