Context

I went through this tutorial on 2019-07-06 with vanilla installs of recommended software applications and updates on a Windows 10 Home x64 machine and encountered a deprecation warning when running 2-Exploratory-Data-Analysis.ipynb in the jupyter notebook.

Issue

Series.nonzero() is deprecated and will be removed in a future version.

Solution

Update code in 2-Exploratory-Data-Analysis.ipynb from original:

uniques = data[comedian].nonzero()[0].size

to

# uniques = data[comedian].nonzero()[0].size (deprecated)
uniques = data[comedian].to_numpy().nonzero()[0].size
