diffusers0.25.0で実装された aMUSEd を試してみる
npakaさんのnoteで0.25.0のリリースを知る。
aMUSEd というアルゴリズムによる画像生成もあるようなので実験してみる。
Hugging Faceのリリースより
Google Colab T4環境で実行してみる
!pip install diffusers
これで 0.25.0がインストールできる。パッケージの依存関係から他のパッケージのバージョンも見ておこう

!pip install diffusers
!pip install accelerate
一度に9枚生成してみた
import torch
from diffusers import AmusedPipeline
# Initialize the pipeline
pipe = AmusedPipeline.from_pretrained(
"amused/amused-512", variant="fp16", torch_dtype=torch.float16
)
pipe.vqvae.to(torch.float32) # Fix for vqvae producing NaNs in fp16
pipe = pipe.to("cuda")
# Define your prompt
num_images = 9
prompt = "miku in dancing"
for i in range(num_images):
image = pipe(prompt, generator=torch.manual_seed(i)).images[0]
image.save(f"miku_in_dancing{i}.png")
ちょっと結果は酷かったので公開するのはやめておきます
image2imageも試してみた。プロンプトは「apple watercolor」。
import torch
from diffusers import AmusedImg2ImgPipeline
from diffusers.utils import load_image
pipe = AmusedImg2ImgPipeline.from_pretrained(
"amused/amused-512", variant="fp16", torch_dtype=torch.float16
)
pipe.vqvae.to(torch.float32) # vqvae is producing nans in fp16
pipe = pipe.to("cuda")
prompt = "apple watercolor"
input_image = (
load_image(
"miku_39.png"
)
.resize((512, 512))
.convert("RGB")
)
image = pipe(prompt, input_image, strength=0.7, generator=torch.manual_seed(39)).images[0]
image.save("image2image_512.png")
速くても美しいとは限らない・・・?
