Do you have a paid enrollment (or financial aid) in the course? ---

That’s fine, it would give you access to the course. Do you actually have the financial aid, or have you only applied for it? ---

Check out this: > [@How to Get a Clean Copy of an Assignment Notebook](https://community.deeplearning.ai/t/how-to-get-a-clean-copy-of-an-assignment-notebook/73): > > If you want to restore the original unmodified state of any of the notebooks or the other files associated with any of the assignments, you can use the “Lab Help” menu of Coursera Labs to do that. The first thing to do is to rename the existing notebook, because this procedure will not overwrite existing files. You need to move the current version of the notebook aside or delete it. The advantage of renaming is that you can later copy any completed work as desired to the fresh copy of the noteb… ---

I am also seeing the same 404 error on that page. @chris.favila, can you explore if the MLS C1 W3 lab (logistic regression) is still available? ---

Hi! Unfortunately, I can’t reproduce the issue. It’s working fine for me even after getting a new copy of the lab. Can you try again now? It might be a temporary bug. Thanks. ---

By any chance, were you already working on the notebook then renamed it afterwards? If so, please click on the jupyter icon above the 404 to open the file tree and select the renamed ipynb file. Please revert it to the original name before submitting to avoid possible bugs with the grader. Alternatively, click the hamburger button on the upper right and select Help → Get Latest Version → Update Lab to get a fresh copy of the notebook. Hope this helps. ---

I’m also getting a 404 error. The lab hasn’t been updated December 2022. I did not rename the notebook file - or at least I don’t remember doing so. But it’s possible since I was testing a student’s notebook four months ago. What is a “hamburger button”? ======= Update: I used “get latest version” tool via the “circle-with-the-question-mark” button, and now I have a copy of the notebook again. ---

If you get the 404 shown earlier in this thread, have you tried the “Get a Clean Copy” procedure that is described on the earlier posts on this thread? Please do that and then let us know whether that fixes the problem for you or not. ---

Yes, I saw your other thread(s). Sorry, but I’m not a mentor for MLS, so we’ll need to wait for someone who knows that assignment to respond. ---
