It is not irregular for books about fast paced languages or libraries to become outdated quickly, but this book was both outdated and full of errata. There is a Github repo of iPython Notebooks to help, but I discovered that the further I went in the book the less accurate even these became to the point where I had to give up following along to the examples because they were so bad.
Instead of reading this book, read the manuals and documentation on scikit learn's website - they are more thorough, up to date, and maybe a little less dry.
