並獲得增強的文件體驗
開始使用
Flux
Flux 是一系列基於擴散轉換器的文字到影像生成模型。
我們建議使用 inf2.24xlarge 例項，並將張量並行大小設定為 8，用於模型編譯和推理。

- 選項 1：CLI
optimum-cli export neuron --model black-forest-labs/FLUX.1-dev --tensor_parallel_size 8 --batch_size 1 --height 1024 --width 1024 --num_images_per_prompt 1 --torch_dtype bfloat16 flux_dev_neuron/- 選項 2：Python API
from optimum.neuron import NeuronFluxPipeline
if __name__ == "__main__":
compiler_args = {"auto_cast": "none"}
input_shapes = {"batch_size": 1, "height": 1024, "width": 1024}
pipe = NeuronFluxPipeline.from_pretrained(
"black-forest-labs/FLUX.1-dev",
torch_dtype=torch.bfloat16,
export=True,
tensor_parallel_size=8,
**compiler_args,
**input_shapes
)
# Save locally
pipe.save_pretrained("flux_dev_neuron_1024_tp8/")
# Upload to the HuggingFace Hub
pipe.push_to_hub(
"flux_dev_neuron_1024_tp8/", repository_id="Jingya/FLUX.1-dev-neuronx-1024x1024-tp8" # Replace with your HF Hub repo id
)Guidance-distilled
- Guidance-distilled 變體需要大約 50 個取樣步驟才能生成高質量的影像。
from optimum.neuron import NeuronFluxPipeline
pipe = NeuronFluxPipeline.from_pretrained("flux_dev_neuron_1024_tp8/")
prompt = "A cat holding a sign that says hello world"
out = pipe(
prompt,
guidance_scale=3.5,
num_inference_steps=50,
generator=torch.Generator("cpu").manual_seed(0)
).images[0]
out.save("flux_optimum.png")
Timestep-distilled
- max_sequence_length 不能超過 256。
- guidance_scale 需要為 0。
- 由於這是一個 timestep-distilled 模型，它受益於更少的取樣步驟。
