I am getting same error. Has there been a resolution to this?

No body is willing to help. I emailed the help center, they say check the forum. I tried all options suggested in the forum. Nothing works. Please help

Hi Ajay! Sorry to hear about your trouble with the submission. Have you tried the suggestions in this topic? These usually solve the issues in the submissions for Course 2. Please let me know. Thanks!

Hi Amit! Welcome to Discourse! As mentioned above, have you tried the suggestions in this topic? Please let me know. Thanks!

Thank you for your help. I do have a problem in Exercise 11 which is the last exercise. There was a thread which said comment out the problematic exercise and i commented the exercise 11. The exercises 1-10 have no problems. I tried all other options, no luck

Hi Ajay! Just to make sure before we look deeper:

  • Have you tried resetting your notebook and copying your old solutions into the new notebook? (Make sure to back up your old notebook and to also save your new notebook before clicking submit!)
  • And with this new notebook, did you run every cell (even those related to exercise 11) and made sure that none of them throws an error?


I resolved this by deleting some pre-populated code.
Specifically fselect folder and related data.csv creation causes issue afterwards.
That file does not get used anywhere in code so deleted it seemed fine. Make sure you comment out the code though. Dont delete the cell itself.
