Hello, in the jupyter notebook all public test passed, but when I submit my assisgnment I get a 0/10 grade.

I will submit an issue on this so the QA team can look into it.

Hi Pedro! Can you open your notebook and save it again then resubmit? Based on the error messages, it seems the grader was grading a blank notebook. Also make sure that you are not working on a renamed notebook (e.g. C1W1_Assignment_1.ipynb). It has to be named exactly as C1W1_Assignment.ipynb which is the default name when you first opened it. Let us know how it goes. Hope it works! Thanks!

Hello Chris! Thank you for the answer but I keep getting the same error. I think my notebook is named correctly. I also opened and saved the notebook again, but still got the error.

Hi Pedro! Please check your inbox. Thanks!

Hi Pedro! It seems you are working on an old version of the notebook. The boilerplate code looks a bit different. Please get the latest version and fill in your answers. Here are the steps to refresh your notebook:

  1. Rename your current notebook.
  2. Click on the ? Help button at the upper right corner of the lab to open the Lab Help sidebar.
  3. Click on Get Latest Version

latest_version
latest_version1010×730 44.6 KB

That should open a blank version of the latest notebook. Please put your answers but be wary of changing any non-graded code (e.g. assigned URI string variables). I think it should work now with those changes. If not, feel free to let us know. Thanks!

Hello! I did these steps and still got the same error.

Even I am having the same issues…:frowning:

Hello! I did these steps and still got the same error.

Hi! Sorry for the delay. Can you post here the value of the URI variables? Thank you.

11

Hi Reevan! Welcome to Discourse! If you’re still having issues, please check your inbox. Thank you!

URI = ‘http://archive.ics.uci.edu/ml/machine-learning-databases/wine-quality/winequality-white.csv’

Hmm… That is strange. Can you rename that notebook and get a fresh one again? Then please post here the blank notebook that you got (i.e. without any of your solutions). It might be a problem with Coursera. I’ve tried several times to refresh my workspace and the URI never points to that. Thank you!

It finally worked out!! Thanks!
