Dear community,
I am currently trying to submit the programming assignment for week4 on the first Neural Network and Deep learning course. I always get the following error message:
I did a bunch of stuff to resolve this issue:
- Cache cleaning
- Different browsers
- Checked that the browsers are set to English
- Clicked on “get latest version” after renaming the workbook and copying everything in the new version
- Rebooted the server
- Deleted the files and restarted everything from scratch
- Asked coursera support but they couldn’t help and referred to this community.
The code is running without errors and I also get the expected results. The only mismatch I see is the name of the file “Building_your_Deep_Neural_Network_Step_by_Step_v8a.ipynb”, the name it is looking for in the error message and the version that is reported in the file under “Updates of the Assignment”:
If you were working on a previous version
- The current notebook filename is version “4a”.
- You can find your work in the file directory as version “4”.
- To see the file directory, click on the Coursera logo at the top left of the notebook.
I have looked for a version 4a but in my directory it is starting with 5. I also tried to rename v8a to v4a just to check.
I encountered the same problems also with the assignments in week 2 and 3. As they were not needed for the grade, I first went through the course, but now it is still not working for week 4.
The course’s name is actually in German (Neurnale Netze und Deep Learning) but except for the title and the test questions, everything is in English. I don’t know if there might be a file mismatch.
Maybe someone has some more ideas how I can fix the issue?
Thanks a lot!
That is apparently not the standard version of this course on Coursera. The assignment file has not had that name since 2021. In the current “official” Coursera version of the course, the name of that notebook should be:
Building_your_Deep_Neural_Network_Step_by_Step.ipynb
Here’s a screenshot of what I see when I click “File → Open” in that assignment. Note that I have a couple of copies of the assignment file in addition to the graded one.
I don’t know what to tell you about the state of that course, since I do not have access to it. Are you taking this through your university instead of directly on Coursera? Why did you chose that version instead of the standard one?
Thanks for your reply!
I am taking this course through my company. They provided the link to the “German” version (which is in English most of the time anyway).
I guess this version was not updated properly…
Yes, if you had the same problem with the Week 2 and Week 3 assignments, it sounds like something is amiss with that version. You might ask your IT folks at your company (or whoever it is that gave you that link) to contact Coursera.
If they are using the 2021 version of DLS, you’ll be missing out on a lot of new material as you proceed through the 5 courses. In Course 1, they didn’t make that many changes in 2021, but in Courses 2, 4 and 5 there were pretty significant updates, including both new material and the fact that they switched from TensorFlow v1 which only supports “graph execution mode” to TF v2 which has “eager mode”. That’s a pretty big deal, so you really want to be on the current versions of the courses.
Thanks a lot for your help, I really appreciate it! I guess I’ll need to retake the course then if I have missed all the new stuff
For Course 1, there isn’t any meaningful difference between the pre-2021 and post-2021 versions. But if you plan to go on and take the rest of the DLS courses (highly recommended!), then there are pretty important additions to DLS Course 2, 4 and 5 even beyond the fact that they switch to TF v2. If your company is sponsoring you to take these courses, then maybe they will support having you enroll in the Coursera version or the version that is provided directly by DeepLearning.AI.
