Problem with Assignment-2

when I submitted assignment 2 and clicked on the submission link the code cells are not showing as executed after question 7 and the grading system says assignment failed: try running all the code cells, but in actuality, I have executed all the cells and completed the assignment.
This occurs when I submit my assignment whereas in colab all the cells are executed end to end.

I’m including screenshots of the colab notebook and of the notebook I got to see when I clicked on the submission link of the submitted assignment.

Thanks.

Hey, save the notebook once before executing jovian.submit(). To save a notebook go to Files tab-> save.
