Exploring Adversarial Machine Learning - Poisoning Assessment

Hey - I’ve definitely saved the file by running the final code block, however I get an error saying missing file. Unsure why that is?
Step6: missing file; SCORE 0 of 16

Disregard. Mixed up the “Steps” from the assessor, and the labelling of the assessment labs.

Although I am unsure why I’m getting "Step5: bad data; SCORE 0 of 16 " for the poisoning assessment. As opposed to even partial marks as I did for previous labs, when my solution wasn’t 100% correct. Unless my solution for this assessment is completely wrong which might very well be the case?

This has been my worst experience taking an assessment. When graded, Step5: bad data; SCORE 0 of 16 for the poisoning assignment. Can anyone help?
