A customer who bought the book (both print and electronic) is reporting that the epub and mobi formats are have sections in foreign languages and titles look strange. It sounds like some kind of bug in the conversion process? The customer is John Gizis (@johngizis on Twitter). Maybe it would be good to get in contact with him to see what the problem is? Update: This has just been confirmed by another customer with the ePub format. Hence, this is not an isolated problem. |

In note that an erratum along these lines has already been noted. I haven't found whole sections of the book not in English (but I haven't looked through the whole eBook). I bought the ebook version and the mobi and epub files seem to have a few bits and pieces in what I think is Polish. The PDF looks fine. Instead of Chapter 1 I have Rozdzial 1. Introduction. Also at the end of the conventions section at the start of the book (just before "Using Code Examples" the text for suggestion/general note and for warning or caution are also not in English (looks like its probably polish again). Comparing the PDF and the mobi format it looks like this is where the PDF has graphical icons. |

Comments in the example suggest that arange(100) will generate the numbers 0 to 100. In fact, it will generate numbers 0 to 99. The comment for arange(10,100) has the same error. Note from the Author or Editor: |

The line in question is: >>> arr3d = np.reshape(arr1s, (10, 10, 10)) Should read: >>> arr2d = np.reshape(arr1d, (10, 10, 10)) Note from the Author or Editor: |

The section in the Scipy Chapter titled "Optimization and Minimization" should be changed to just "Optimization". The error is minor, but it should be corrected. |
