Heya,

I’m struggling to get the expected test numbers on the Book Recommendation Machine Learning Challenge .

I deleted all ratings from users with less than 200 ratings and all ratings from books with less than 100 ratings. Then I pass the remaining ratings into a csr_matrix where I replace missing values with 0. When I pass this into my NearestNeighbour-fit, I’m getting other results though. It gives me recommendations, but except for 2 books, they are not the expected ones and the distances are off by magnitudes. Could it be that the dataset changed as well?

These are the recommendations and distances I get for the test:

```
[
"Where the Heart Is (Oprah's Book Club (Paperback))",
[
['The Surgeon', 61.286213],
['Unspeakable', 61.522354],
['The Perks of Being a Wallflower', 61.579216],
['Gap Creek: The Story Of A Marriage', 61.676575],
['The Weight of Water', 61.75759]
]
]
```

Down below is the link to my google colab, would be thankful for any feedback
