Somebody please package the html into a pdf!
mkdir dlbook;cd dlbook;wget --recursive --level=1 http://www.deeplearningbook.org/
cd www.deeplearningbook.org/contents
python
import pdfkit
pdfkit.from_file(
["TOC.html","acknowledgements.html","notation.html","intro.html","part_basics.html","linear_algebra.html","prob.html","numerical.html","ml.html","part_practical.html","mlp.html","regularization.html","optimization.html","convnets.html","rnn.html","guidelines.html","applications.html","part_research.html","linear_factors.html","autoencoders.html","representation.html","graphical_models.html","monte_carlo.html","partition.html","inference.html","generative_models.html","bib.html","index-.html"],
"Goodfellow-et-al-2016-Book.pdf")
edit: changed ".pdf" from a slightly longer approach to ".html" which actually exists in this workflow. Thanks @TheCabin!
edit(2): ... and gave a valid path to this listdir. Check before I post... check before I post...
edit(3): ... and removed the os.listdir line no longer needed in this approach. Gosh. Just ignore what I was saying and build your own approach. That'll probably be faster at this rate.
edit(4): Don't import os without using it.
Avoids the awkward file system structure by using pdfkit.from_url, but creates one .pdf for each chapter. I tried using a list of urls, but pdfkit failed because my version of wkhtmltopdf did not accept multiple input files.
Edit: pdfkit.from_file also fails on my system when passing multiple files. If that works for you, multiple urls are probably fine, too.
I think it was a mistake to try shaving off a couple of lines and a step at the price of a more convoluted install and a brittle process. Most people would probably be best off just converting one HTML file at a time to pdf (e.g. pdfkit.from_file(filename_in_html,filename_in_html[:-4]+".pdf") in some sort of iteration over the file names) and then concatenating the resulting PDF:s, for instance from command line by
pdftk TOC.pdf acknowledgements.pdf notation.pdf intro.pdf part_basics.pdf linear_algebra.pdf prob.pdf numerical.pdf ml.pdf part_practical.pdf mlp.pdf regularization.pdf optimization.pdf convnets.pdf rnn.pdf guidelines.pdf applications.pdf part_research.pdf linear_factors.pdf autoencoders.pdf representation.pdf graphical_models.pdf monte_carlo.pdf partition.pdf inference.pdf generative_models.pdf bib.pdf index-.pdf cat output Goodfellow-et-al-2016-Book.pdf
find . -iname '*.html' -exec wkhtmltopdf {} {}.pdf \;
There are also tools to convert the resulting files to a single pdf. The only problem I got is, that the woff fonts are not rendered by "wkhtmltopdf" :-/ Ideas?
If I want this book in hard copy, then I will purchase it - I've done this regularly with free digital books - but when it is offered free digitally then in my opinion prohibiting to only certain file formats is futile (as evidenced here), and such constraints are ineffective attempts to encourage people to buy the hard copy through inconvenience.
And I must add that this is no slight to the authors, whom have my greatest appreciation for compiling their vast knowledge into a book and offering it for free. These guys are legends.

Personally, I was looking for an ePub version but no biggie.
