The crosstab function has been refactored between 0.13 and 0.16. See github.com/pydata/pandas/issues/6581.

In 0.16 the crosstab result is empty:

In [69] : party_counts = pd.crosstab(tips.day, tips.size)
In [70]: party_counts
Out [70]:
Empty DataFrame
Columns: []
Index: [Fri, Sat, Sun, Thur]

And breaks the generation of Figure 8-18 on page 238. Rewriting crosstab as follows appears to work in 0.13 and 0.16:

In [69] : party_counts = pd.crosstab(tips['day'], tips['size'])
