TypeError: Int64 when running jb2.pivot_table

[dougler]

I have been following the code in your book in jupyter notebook.
There is several places where the code leads to errors. The errors also show up in the github version of the code.
For example:
In the your notebook Chapters 16-30 (page 302 in the physical book)
input 106 and 107 lead to errors. Have they been corrected?

(jb2
 .pivot_table(index='country_live', columns='employment_status',
     values='age', aggfunc='mean')
)

Thanks for reporting @dougler .

I have raised this issue in pandas pandas-dev/pandas#47477
