Need help: My notebook isn't saving not submitting

Course Q&A Deep Learning Specialization Improving Deep Neural Networks: Hyperparameter tun
1

My Jupyter notebook for the “Optimization Methods” assignment is giving me “permission denied: release/W2A1/Optimization_methods.ipynb” error. I exported the IPYNB file and completed it off of the Coursera server. I could submit it to a TA to grade offline.

Otherwise, I tried everything on coursera to reboot and restart the jupyter notebook server. It didn’t fix the system.

Thank you

Hi @Enes_Grahovac!

We are extremely sorry for the inconvenience. Several learners facing this issue. We already informed the course staff to look into the issue as soon as possible.

Your patience will be highly appreciated. Once they resolve the issue, we will inform you.

Best,
Saif

Hi everyone! Sorry for the delay.

Kindly try this:

  1. From the blank notebook, click File -> Open.
  2. Tick the running notebook.
  3. Click Shutdown then Duplicate.
  4. Rename the old notebook (any filename).
  5. Rename the duplicate with the original filename (basically, just remove the -Copy1 string).
  6. Open this newly renamed notebook.
  7. You should be able to save this and also see the submit button after a minute.

You “might see an error about checkpoints failing. I think that’s okay because that’s related to the permissions of the hidden .ipynb_checkpoints folder. That is not needed for grading as far as I know. The changes should persist in the actual notebook itself even if they see that error. I submitted the notebook and got the expected grade.”

Best,
Saif.

@saifkhanengr I am getting [ An error occurred while renaming Building_your_Deep_Neural_Network_Step_by_Step.ipynb" to “dd.ipynb”. Permission denied: release/W4A1/dd.ipynb].
I can’t make any changes in the working lab.

Hi @HIDAYA_BOUCHOUKA,

I think Cousera is trying to fix it, but just in case you are still experiencing the permission error, I have tagged you in another post about a workaround that you may try while we are waiting for a fix by Cousera.
