Test cosine similarity, Test euclidean, Test_get_country, Test get_accuracy, test compute pca. All of them show the same error message: “There was an error in one or more parts of your submision. Graded error. We could not find the graders comment”
I have this error from one month ago and I cannot end the course.
You probably accidentally removed #UNQ_ comments from your notebook.
In any case, the best way for you to complete the course is to get a fresh copy (how to refresh) of your assignment and carefully complete the blocks (start code here … end code here).
Also while redoing please make sure you do not do this.
Cheers
