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: “This is done using tf.gather(self.beta, labels), which is conceptually equivalent to beta = self.beta[labels], as follows.”

A block of code is set as follows:

attn = tf.matmul(theta, phi, transpose_b=True)attn = tf.nn.softmax(attn)

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

self.conv_theta = Conv2D(c//8, 1, padding='same',              	                   kernel_constraint=SpectralNorm(),  	 	                   name='Conv_Theta')

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

$ mkdir css
$ cd css

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: “From the preceding architecture diagram, we can see that G1's encoder output concatenates with G1's features and feeds into the decoder part of G2 to generate high-resolution images.”
