r of channels in the latent space.   norm_num_groups (int, optional, defaults to 32) —
The number of groups for normalization.   sample_size (int, optional, defaults to 32) —
Sample input size.   scaling_factor (float, optional, defaults to 0.18215) —
The component-wise standard deviation of the trained latent space computed using the first batch of the
training set. This is used to scale the latent space to have unit variance when training the
