Unable to submit week2 assignment

Seems like I have the same error.

I have already tried the following:

  1. Reset to the Original Version
  2. Saved the notebook as suggested in a previous reply.
  3. Saved the training model, states “Model saved to trained_student_model.pth”
  4. All the unit tests show passed.

I have tried about 9-10 times already

ii will send! you DM, please send me your notebook there.

Hello learners,

This looks like an environment issue faced by few learners for grader submission. Unfortunately, as it is weekend, staff will look upon this issue soon and report back.

I have shared all your necessary details with staff. So appreciate you all to raise this issue and understanding to resolve this concern.

For now I am closing this topic, until staff can respond back with what they found with your copy or environment. Kindly wait for their response on this topic by Monday.

Regards

Hi @picnic, @AIKen, @pallavichakraborty

I have reset the environment and checked, everything seems to be working now. Hopefully, it will work for you as well.

Note: These instructions only apply to students taking the course on DeepLearning.AI’s Learning Platform.

Please do the following:

  • Open the C1 M2 Assignment

  • Restore your environment: I would recommend doing this to make sure you have the latest environment, and my other recommendation would be to attempt the assignment from scratch instead of using your old solutions/notebook.

    Once your assignment opens, click on the three dots on the right side of the panel, and then click “Restore Original Version”

  • Wait for your workspace to reset and open again. And then attempt the assignment again.

  • This assignment (which should be attempted in the notebook named C1M2_Assignment.ipynb), along with the notebook also needs the trained model for grading, so make sure you have ran every cell up to “Submission Note” markdown to ensure the train model has been saved in your workspace.

  • The click on “Submit”.

If the problem still remains even after following all of the steps above, let me know.

Best,
Mubsi

Was able to submit today. I restored the original version and copy-pasted from a backup.
