Hi,
Thanks for the great work.
Which dataset was used for the pre-trained LDM?
And which checkpoint was used and is it from here (?): https://github.com/CompVis/latent-diffusion
Also is it the same pre-trained Encoder-Decoder for all experiments (Imagenet and Openimages) or different checkpoints on different datasets?
Thank you!
