I’m done all exericices regarding assignement week3 and I passed all, but, When I submit the file 2 exercices did not work.
I probably modified some cells and for this it gives me the final errors. I not remember which and where i modified cell , Does anyone know if and how it is possible to restore the initial file to redo all the exercises from scratch with a new file?
Yeah either on the coursera environment should be a Lab refresh option or just search in google “coursera jupyter force refresh”. It will give you the required instructions
Rename your existing Jupyter Notebook within the individual notebook view
In the notebook view, add “?forceRefresh=true” to the end of your notebook URL
Reload the screen
but did not work infact i find a previous version which however has the same problems and I have not found the original version which is the one that interests me to repeat the entire exercise
I think I overwrote the original version maybe that’s why the refresh doesn’t give me back the initial version. there should be somewhere the original version and give it to me to upload … I think
I have added the original version of the assignment in your workspace.
When your assignment loads, click on File → Open..., when the workspace lands you’ll see two assignment files in there:
previous_C1_W3_Assignment.ipynb, this is the old assignment version you were working on.
C1_W3_Assignment.ipynb, this is the original assignment version.
Two things to remember:
Recently, the “Table of Contents” was added in the assignment, which is why you won’t see it in the previous version, but you’ll see it in the now original version. Other than the table of content, both of the assignments are still the same. There’s no other change.
When you press the button to “Submit” the assignment for grading, the file with the name C1_W3_Assignment.ipynb will be submitted. So please make sure, from now onwards, you are working in that file.
For me, when I finished the assignment C1_W3_Assignment.ipynb, I don’t remember the error but all the contents of the notebook disappeared, now my notebook is empty… Can you help me find my notebook please.
You will have to get a fresh copy and re-do the assignment as it seems somehow the whole assignment is deleted and I cannot state the reason for this as I wasn’t there when this happened with you.
Note that you will need to either delete or rename the existing blank notebook first or else the “Get Latest Version” procedure will not give you a new fresh copy.
Do “File → Rename” first and then click ? in the upper right border followed by “Get Latest Version”.
If those instructions are too brief, here’s a thread that goes through everything in excruciating detail.
