Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The library we are using for datasets loading and manipulation is pandas."

A block of code is set as follows:

let bundle = Bundle.main 
let assetPath = bundle.url(forResource: "DecisionTree", withExtension:"mlmodelc") 

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

let metricsSKLRandomForest = evaluateAccuracy(yVecTest: groundTruth, predictions: predictionsSKLRandomForest) 
print(metricsSKLRandomForest) 

Any command-line input or output is written as follows:

> pip install -U numpy scipy matplotlib ipython jupyter scikit-learn pydotplus coremltools

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "In the interface, the user selects the type of motion he wants to record, and presses the Record button."
