Using Python 3.5.3 and Listing 3.4 "Splitting the dataset into testing and training", I get the following error,
TypeError: slice indices must be integers or None or have an __index__ method
To get rid of the error I had to put "ratio * x_dataset.size" into an int() function, to look like this,

num_train = int(ratio * x_dataset.size)
