Method __init__

models/base_model.py:17–43

Initialize the BaseModel class. Parameters: opt (Option class)-- stores all the experiment flags; needs to be a subclass of BaseOptions When creating your custom class, you need to implement your own initialization. In this fucntion, you should first call <BaseM

(self, opt)

            -- self.model_names (str list):         specify the images that you want to display and save.
            -- self.visual_names (str list):        define networks used in our training.
            -- self.optimizers (optimizer list):    define and initialize optimizers. You can define one optimizer for each network. If two networks are updated at the same time, you can use itertools.chain to group them. See cycle_gan_model.py for an example.
