# Note about this data
## Expected outputs
`expected_*.png` files are the output of the same diffusion run with a different codebase, usually diffusers with the same settings as us (`DPMSolverMultistepScheduler`, VAE [patched to remove randomness](#vae-without-randomness), same seed...).
For instance here is how we generate `expected_std_random_init.png`:
```py
import torch
from diffusers import DPMSolverMultistepScheduler
from diffusers import StableDiffusionPipeline
pipe = StableDiffusionPipeline.from_pretrained(
"runwayml/stable-diffusion-v1-5",
torch_dtype=torch.float32,
).to("cuda")
2023-08-04 13:28:41 +00:00
pipe.scheduler = DPMSolverMultistepScheduler.from_config(pipe.scheduler.config)
prompt = "a cute cat, detailed high-quality professional image"
negative_prompt = "lowres, bad anatomy, bad hands, cropped, worst quality"
torch.manual_seed(2)
output = pipe(
prompt=prompt,
negative_prompt=negative_prompt,
num_inference_steps=30,
guidance_scale=7.5,
)
output.images[0].save("std_random_init_expected.png")
```
Special cases:
- For self-attention guidance, `StableDiffusionSAGPipeline` has been used instead of the default pipeline.
2023-08-04 13:28:41 +00:00
- `expected_refonly.png` has been generated [with Stable Diffusion web UI](https://github.com/AUTOMATIC1111/stable-diffusion-webui).
2023-09-24 20:05:56 +00:00

## Other images
- `cutecat_init.png` is generated with the same Diffusers script and prompt but with seed 1234.
- `kitchen_dog.png` is generated with the same Diffusers script and negative prompt, seed 12, positive prompt "a small brown dog, detailed high-quality professional image, sitting on a chair, in a kitchen".
- `expected_std_sde_random_init.png` is generated with the following code:
```python
import torch
from diffusers import StableDiffusionPipeline
from diffusers.schedulers.scheduling_dpmsolver_multistep import DPMSolverMultistepScheduler
from refiners.fluxion.utils import manual_seed
diffusers_solver = DPMSolverMultistepScheduler.from_config( # type: ignore

"beta_end": 0.012,
"beta_schedule": "scaled_linear",
"beta_start": 0.00085,
"algorithm_type": "sde-dpmsolver++",
"use_karras_sigmas": False,
"final_sigmas_type": "sigma_min",
"euler_at_final": True,
}
)
model_id = "runwayml/stable-diffusion-v1-5"
pipe = StableDiffusionPipeline.from_pretrained(model_id, torch_dtype=torch.float32, scheduler=diffusers_solver)
pipe = pipe.to("cuda")
prompt = "a cute cat, detailed high-quality professional image"
negative_prompt = "lowres, bad anatomy, bad hands, cropped, worst quality"
manual_seed(2)
image = pipe(prompt, negative_prompt=negative_prompt, guidance_scale=7.5).images[0]
```
