Week 4 assignment fail despite showing 99.9% in the lab

The grade score was 67%.
The accuracy was reported as 93%.

The jupyter notebook is opened in Google colab. I’m doing this course via coursera, so there may be a difference if there are other ways to be on this course?

I’ll send a screenshot perhaps when I try again later.

Anyway my point is, the model accuracy is reported differently in the notebook for some reason, so I’ve no baseline to check whether I’m doing it better or worse if I can’t tie the model accuracy back to whatever the grader process is doing. I’ve passed the other three assignments in this first module, so it was fine previously.
