Conventions used

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

Code in text: 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: "Keras offers a method in the model to get the probability, predict(), and one to get the label, predict_classes()."

A block of code is set as follows:

img_threshold = np.zeros_like(channel)
img_threshold [(channel >= 180)] = 255

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

[default]
exten => s,1,Dial(Zap/1|30)
exten => s,2,Voicemail(u100)
exten => s,102,Voicemail(b100)
exten => i,1,Voicemail(s0)

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

/opt/carla-simulator/

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: "The reference trajectory is the desired trajectory of the controlled variable; for example, the lateral position of the vehicle in the lane."
