Parameters   x (torch.FloatTensor) — Input batch of images.   return_dict (bool, optional, defaults to True) —
Whether or not to return a ~models.autoencoder_kl.AutoencoderKLOutput instead of a plain tuple.   Returns 
~models.autoencoder_kl.AutoencoderKLOutput or tuple
  
If return_dict is True, a ~models.autoencoder_kl.AutoencoderKLOutput is returned, otherwise a plain
tuple is returned.
  Encode a batch of images using a tiled encoder. When t
