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: "Install the matplotlib, pillow, lxml, and jupyter libraries. On Ubuntu or Mac, you can run."

A block of code is set as follows:

syntax = "proto2";
package object_detection.protos;
message StringIntLabelMapItem {
  optional string name = 1;
  optional int32 id = 2;
  optional string display_name = 3;
};

message StringIntLabelMap {
  repeated StringIntLabelMapItem item = 1;
};

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

sudo pip install pillow
sudo pip install lxml
sudo pip install jupyter
sudo pip install matplotlib
