Perhaps you have copied the UNQ_C1 cell in another cell! In any case if you reset the assignment you should have a clear start again.

If you continu to experient the same pb, delete the notebook, and then, click to help “button” to reload a new notebook…

The “AI Discussions” forum is not the place to ask questions about a specific course.

I have moved the thread to the correct forum topic.

There’s nothing duplicated there are 2 exercises
With comments UNQ_C1,UNQC2 there is no cell have the same comment ، in fact i don’t know what can i do

Another issue to check: Did you perhaps rename your notebook ipynb file?
Or do you have two copies of that notebook file?

[Aboeid25]

i renamed this path only, i also tried kernel restart , update lab , reboot server but it didn’t work , if you have a way to reset this all please tell me

@Aboeid25

i renamed this path only,

That is a problem. Please put it back the way it was originally. “joyvan” is the folder name of the DLAI developer for this assignment, somehow it got baked into the grader as well.

Unfortunately I couldn’t do this, is there no way to restart the assignment from the beginning with re-downloading the lab files?

I’m not sure I understand what you mean when you say “I renamed this path only…”

Here is what my lab shows when I look at the Lab Files tab (I’m only showing the path and folders, not the individual files).

Does yours look different? What have you changed specifically?
