Bad request error when submitting labs in Russian version of “Convolutional Neural Networks” (schema not found)

Course Q&A Deep Learning Specialization Convolutional Neural Networks
,
1

Hello,

I am taking the Russian‑language version of the course “Convolutional Neural Networks” by DeepLearning.AI on Coursera (URL looks like …/convolutional-neural-networks-ru).

When I try to submit any Jupyter Notebook assignment using the Submit button in the lab environment, I consistently get the following error message:

Bad request: {‘errorCode’: None, ‘message’: "Could not find schemas with name(s): ‘convolutional-neural-networks~qO8ng’. ", ‘details’: None}

This error appears immediately after pressing Submit, even for the original, untouched notebook, so it does not seem to be related to my code changes in the graded cells.

I have already tried the usual troubleshooting steps:

  • Restarting the kernel and using “Restart & Clear Output”, then running all cells again before submitting.

  • Using “Get latest version” / reopening the lab to get a fresh copy of the notebook.

  • Making sure I did not rename the notebook file and that I only edited the cells marked with ### START CODE HERE ###.

  • Trying another browser.

The error message stays the same and still complains about missing schema convolutional-neural-networks~qO8ng.

I also contacted Coursera support, but they could not provide a technical fix and mentioned that it may be related to changes in the course configuration or grader setup. From the error text it looks like the grader is trying to use a schema that does not exist or is not correctly linked to my version of the course.

Could you please help with one of the following:

  1. Re‑assign my enrollment to a working schema for this course, or

  2. Move my enrollment from the Russian‑language version to the corresponding English‑language version of “Convolutional Neural Networks” where the autograder is correctly configured, while preserving my progress and payment?

My goal is to continue the specialization and be able to submit the programming assignments normally. Right now, the course is blocked for me at the point of lab submission.

If you need any additional information (screenshots, my Coursera profile email, exact course URL, etc.), I will be happy to provide it.

Thank you in advance for your help.

Best regards,
Artem Semkin

Hello @Mubsi,

It seems to be the same problem as this one. Is there anything you can do about it?

Cheers,
