To readers of “Programming Machine Learning”: the code in the book runs on old-ish versions of Python and its libraries. If you have trouble running the examples, look for updated code and installation instructions on this GitHub repo. I made a number of small tweaks to the code so that it runs on recent versions of Python, NumPy, etc.
I’ll keep the repo updated whenever bitrot sets in. If you still have trouble running the code, please drop me a message on this forum I’ll check out the issue and update the repo.
