@fpcoutinho oh no, did you edited the metadata at a cell level or did you edit it for the whole notebook? That error message is due to a parameter at the notebook level that controls the current version of the assignment so that it is aligned with the latest grader version (we have this since sometimes coursera fails to show the latest version of the assignment). I believe in your case it it better to get a fresh copy of the notebook. If you want a fresh copy of the notebook you can do so by following this steps:
- Click on the Jupyter logo in the upper left corner of the screen (this will take you to the jupyter filesystem)
- There select the C3_W1_Assignment.ipynb file and click the shutdown button
- Select it again and click the rename button and rename the file
- Now click on Coursera’s Help button in the upper right corner of the screen and click the “Get Latest Version” button
This will bring you a blank C3_W1_Assignment.ipynb file, which you can add your changes to and then submit for grading.
@simplyjaga, happy to help! You can follow the previous steps to get a fresh notebook since updating metadata for several cells can be annoying.
