How to train LSUN Church dataset on latent diffusion model?

[hxy-123-coder]

Thanks to your great work! I did experiment on LSUN Church dataset.Following on your paper, global conditions of this dataset is provided by a U-Net's encoder. After that, train another latent diffusion model for unconditional image synthesis by the pretrained model. But the loading model code is for your own landscape images not for low resolution images.I wonder how to train LSUN Church dataset on latent diffusion model?Sincerely looking forward to your reply.
