I have a problem with the grader even when all tests are passed it gives zero grading raising the following type error Unsupported operand types for None type and float at cell #12
Noted: all the notebook cells run without errors, all the tests passed, the notebook saved and finally submitted the notebook.
Can you share your lab ID with me ? I’ll take an in depth look at your notebook. When you are in your assignment, you’ll see a “Help” icon on the top right, when you’ll click on it the panel will open and your lab ID will be shown at the bottom.
