This is a known problem with Coursera’s lab environment.
It’s been reported, hopefully they will fix it soon.
Could you please let me know when this issue is resolved, thank you.
We will inform you.
I also have the same problem in week 4 of the course " Neural Networks and Deep Learning"
Could you please fix it?
Hi everyone! Sorry for the delay.
Kindly try this:
- From the blank notebook, click
File -> Open.
- Tick the running notebook.
- Rename the old notebook (any filename).
- Rename the duplicate with the original filename (basically, just remove the
- Open this newly renamed notebook.
- 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.”
Duplicate does not work. Says permission denied. I think the issue is that we don’t have write permissions in the directory.
Yes, as @pkumar13 stated, it gives the permission error as we want to duplicate the file. I think if you grant permission to the .ipynb file, the problem will be fixed and there would be no need to duplicate the file and do the rest of the steps.
We informed the course staff about Duplicate failed. We are extremely sorry for the inconvenience.
