AsymmetricAutoencoderKL  
Designing a Better Asymmetric VQGAN for StableDiffusion https://arxiv.org/abs/2306.04632 . A VAE model with KL loss
for encoding images into latents and decoding latent representations into images.  
This model inherits from [`ModelMixin`]. Check the superclass documentation for it's generic methods implemented
for all models (such as downloading or saving).  
Parameters:
in_channels (int, *optional*, defaults to 3): Number of channels in the input image.
