And now it passed, strange? No changes were made to any methods. One possibility is that there was incorrect indentation but wouldn’t the unittests.test_DoublyLinkedListFixed(DoublyLinkedListFixed) fail in this case as well?
It seems you didn’t save your solution before submitting, so the autograder received an empty doubly linked list instead of your solution. Although it works when you run it in the notebook, the notebook doesn’t save automatically. It does save periodically, but it’s recommended to always save the notebook before submitting.
I passed all test in my notebook but am getting this message when I submit my assignment for all 4 of my exercises. I am confused because it is referencing the Stack Class, which I left unedited as instructed. I also made sure to save my solutions. Is there something else that I may be missing?
After I refreshed the Notebook, I simply added my edited code to the exercise blocks. All other cells have not been modified and no external libraries have been imported. I have repeated once more to be sure. Still no luck.
Running into the same problem. For me is_palindrome_fixed and dijkstra_fixed are accepted, StackFixed and DoublyLinkedListFixed are rejected. All problems pass all tests when running in the notebook. I tried Rebooting, Updating the work space, I remove all extra cells, I saved the notebook. Makes no difference. What else can I try?
OK. Here is what worked for me. Move all existing files into a backup folder. Then go to Get Latest Version (from the ? menu item). This will replace all files so they are all original. Then I copy/pasted the fixed code into the existing cell without adding or removing any cells. Voila.
I am having issue after submitting. The code passed all the test but after submitting, I am getting this:
There was a problem compiling the code from your notebook, please check that you saved before submitting. Details:
inconsistent use of tabs and spaces in indentation (, line 122)
