C5_W4_A1_Transformer_Subclass_v1 inconsistent grader

I’m going to suggest is that the issue is with the auto-save feature in Coursera’s Jupyter platform.

Most likely the first time you submitted your work, the notebook had not yet been auto-saved, so it was grading your previous work. By the time you submitted it again, the auto-save had activated.
