Looping the process of writing images into the .tfrecords-file works fine, but how do I read multiple images from a .tfrecords-file?

Is there any simple solution? would be great if added to the code.

Chapter number or note title: Chapter 0, Exercise 2, Footnote 24

Page number: 17

Error description: The footnote says "Ja, das ist das [...]maschine". However, the German language has 3 different articles (der, die das). In this particular case, you want "die" instead of "das" [...]maschine.

Suggested fix (if any):
Ja, das ist die Subatomar[...]maschine.

Jupyter containers hosted by Coursera cause a lot of trouble. Perhaps more than they are worth.

• They are very limited in terms of lifetime and CPU. The docs say 90 minutes / 0.5-2 CPUs. That's definitely insufficient to train Breakout, for example.
• Updating them is inconvenient. We don't h

In https://github.com/csev/py4e/blob/master/book3/01-intro.mkd, I would like to suggest to improve readability by adding a space after the colon in:

python words.py
Enter file:words.txt
to 16

I.e., replace it by

python words.py
Enter file: words.txt
to 16

I think Brett wrote a related concept check... Maybe already did this completely. Should basically talk about eigenvector, eigenvalues, and connection to principal axes.

Also -- what does solution set look like when X is not full rank. current treatment is imprecise.

In this example the generated table of contents doesn't link to the sections on the page, because the headers have anchor tags in them. These should be sanitized out.

Please download/fork and compile the source tex files as per README instructions. Let me know if you face any issues, any changes, etc.
