[https://github.com/liaopeiyuan/artbench](ArtBench) samples encoded to float16 SDXL latents via [Ollin VAE](https://huggingface.co/madebyollin/sdxl-vae-fp16-fix).
Dataset created using [this script](https://github.com/Birch-san/sdxl-diffusion-decoder/blob/main/script/make_sdxl_latent_dataset.py).
Didn't bother saving mean & logvar, because variance is low enough it's not worth the doubling of filesize to retain.
Sampled from diagonal gaussian distribution, saved the resulting latents.
Also kept the original image.
Schema/usage:
```python
from typing import TypedDict, Iterator
from webdataset import WebDataset
Sample = TypedDict('Sample', {
'__key__': str,
'__url__': str,
'cls.txt': bytes, # UTF-8 encoded class id from 0 to 9 inclusive
'img.png': bytes, # PIL image, serialized. 256*256px
'latent.pth': bytes, # FloatTensor, serialized. 32*32 latents
})
it: Iterator[Sample] = WebDataset('train/{00000..00004}.tar')
for sample in it:
pass
```
