The imagenet1k dataset in the webdataset format
Each image was resized so that the max side resolution is 256, making sure to preserve aspect ratio. Each image was encoded to latents using the sixteen channel https://huggingface.co/ostris/vae-kl-f8-d16 No cropping was used to encode to latents!
The resulting dataset has images in their original aspect ratio, but much smaller, and encodeded with a vae.
