The content on ja.d2l.ai, including the online book, downloadable Jupyter notebooks, and the provided PDF, appears to be outdated and incomplete. Specifically, the available materials only cover the sections 事前準備 and はじめに. This is not just a matter of incomplete translations; the rest of the content seems to be missing entirely.
Could you please confirm if there are plans to update or complete the Japanese version of the book?
Thanks in advance for your time and for maintaining this great project!
