about parameters

[Joll123]

Could you explain what the following parameters mean？
parser.add_argument('--nz', default=8, type=int, help="number of latent variables, greater or equal to 1")
parser.add_argument('--zchannels', default=1, type=int, help="number of channels for the latent variables")
parser.add_argument('--nprocessing', default=4, type=int, help='number of processing layers')
