I have tried to upload the task several times but it keeps having the same errors, i have tried to reset the kernel but it does nothing and I have check the list of requierements to give a programation task but it doesn’t have any error in my opinion. I am also trying to reset the notebook but I can’t because on the list of steps i am not able to do step 3:

  1. Open the notebook from the classroom.
  2. After the notebook opens up, click File → Open
  3. When your workspace opens, tick the check box before your notebook file. After it is selected, press Shutdown. The icon beside the filename should turn from green to gray.
  4. Tick the checkbox again and this time choose Rename and enter any filename other than the original. For example, C1_W1_Assignment.ipynb (original) → C1_W1_Assignment_v2.ipynb
  5. (Optional) Tick the checkbox of any other file that you want to get a fresh copy of (e.g. dataset files that you might have manipulated irreversibly). Then click Delete . You can also opt to Rename or Download each file individually in case you want to keep them before deleting.
  6. Click on the Help button on the top right of the page.
  7. Click the Get latest version button.
  8. Click the Update Lab button. The page will refresh and you should now see the latest version of the notebook.
