The errata pages here refer to completely different chapter names, and a different BOOK as far as I can tell. For example, in the real book chapter 2 is called "Building a Custom Corpus", not "Text Acquisition and Ingestion". |

calls to grigram_counts.ngrams[3] and trigram_counts.ngrams[3].conditions() seem to be calling on an instance of FreqDist() when they should be calling on the instance of ConditionalFreqDist which is trigram_counts.allgrams. Looking at the nltk documentation the FreqDist doesn't have a conditions() method which makes me think the book is incorrect. |
