Wrong submission, Week 5, exercise "building your deep NN step by step"

Hello !

I was working on this exercise and I guess that I submitted it not on purpose (without finishing it), cuz I found I sumission from the 27/03/2022, with score 0.

Anyways, I would like to continue working on it, but I lost all the code I had already done.

Could you tell me if there’s any way to get back the work I had done ?

Is there any way to continue working from the failed submision ?

Thanks,

Luis

Hi @Luis_David_Alvarez_C. You are talking about DLS course1, week 4, Assignment 1. Yes, the lab has been updated lately. If you have saved your work before submission then probably you can go to File—> open–> .py file with the previous version of your work. Open it up and check whether it carries all your codes. If it is so then go to the file again—open the newly updated notebook and copy paste each of your codes by making sure, you are also working as per the newly guided instructions and inclusions in the updated lab.

It’s always safe to download a file of your work in your local computer. Let me know if that works for you. Thanks.

Yes, if the notebook was updated by the course staff, then your previous notebook gets moved aside with the date and time interpolated into the name. Also note that the file extension of the notebooks is .ipynb, not .py as @Rashmi said.

Also note that it’s not a problem to “submit” as many times as you like, even with partial scores. No harm is done by that and the system is smart enough to remember your highest score. Some people like to use partial submissions to check their work on the earlier functions in the assignment, but be aware that doesn’t always work: sometimes if there are incomplete sections later, it causes syntax errors and the grader will just throw an error and give 0 points on everything, even though you might have successfully completed some of the functions.
