## Ejemplo
|
|
|
|
```python
|
|
from diffusers_load_pipeline import diffusers_load_pipeline
|
|
from diffusers_generate import diffusers_generate
|
|
from generation_config import GenerationConfig
|
|
from model_ref import ModelRef
|
|
|
|
model = ModelRef(
|
|
name="sd-turbo",
|
|
model_type="sd15",
|
|
path="/home/lucas/vaults/imagegen_models/diffusers/sd-turbo",
|
|
)
|
|
cfg = GenerationConfig(
|
|
prompt="a photo of a cat",
|
|
seed=42,
|
|
steps=1,
|
|
cfg_scale=0.0,
|
|
sampler="euler",
|
|
width=512,
|
|
height=512,
|
|
model=model,
|
|
)
|
|
pipe = diffusers_load_pipeline(model, device="cuda", dtype="fp16")
|
|
result = diffusers_generate(pipe, cfg)
|
|
# result.image -> PIL.Image.Image 512x512
|
|
# result.duration_ms -> int > 0
|
|
# result.meta["backend"] -> "diffusers"
|
|
```
|
|
|
|
## Notas
|
|
|
|
`cfg.seed = -1` genera seed aleatorio basado en `time.time()` (reproducible si
|
|
se guarda en `result.meta["seed"]`).
|
|
|
|
VRAM: `torch.cuda.reset_peak_memory_stats()` antes de inferencia,
|
|
`torch.cuda.max_memory_allocated() // 1024 // 1024` despues.
|
|
|
|
`genconfig_to_diffusers_kwargs` omite generator=None; esta funcion lo reemplaza
|
|
con `torch.Generator(device=device).manual_seed(seed)`.

Import lazy de torch — ImportError descriptivo si no instalado.
