StableDiffusion文生圖模型

說明

支持的領域 / 任務:aigc

StableDiffusion文生圖模型目前針對開源社區的stable-diffusion-v1.5版本和stable-diffusion-xl版本進行了服務化支持。

其中,stable-diffusion-v1.5模型通過clip模型能夠將文本的embedding和圖片embedding映射到相同空間,從而通過輸入文本并結合unet的穩定擴散預測噪聲的能力,生成圖片。是一款基礎的文生圖模型,得到了業界廣泛使用。而stable-diffusion-xl相比于v1.5做了重大的改進,被認為是當前開源文生圖模型的SOTA水準,具體改進之處包括: 更大的unet backbone,是之前的3倍; 增加了refinement模塊用于改善生成圖片的質量;更高效的訓練技巧等。

前提條件

示例代碼

以下示例展示了調用 stable-diffusion-xl 模型API進行文生圖的示例代碼,如果需要調用 Stable Diffusion v1.5版本只需要用 stable-diffusion-v1.5 替換 stable-diffusion-xl 即可。

說明

需要使用您的api-key替換示例中的 your-dashscope-api-key ,代碼才能正常運行。

from http import HTTPStatus
from urllib.parse import urlparse, unquote
from pathlib import PurePosixPath
import requests
import dashscope

model = "stable-diffusion-xl"
prompt = "Eagle flying freely in the blue sky and white clouds"


def simple_call():
    rsp = dashscope.ImageSynthesis.call(model=model,
                                        prompt=prompt,
                                        negative_prompt="garfield",
                                        n=1,
                                        size='1024*1024')
    if rsp.status_code == HTTPStatus.OK:
        print(rsp.output)
        print(rsp.usage)
        # save file to current directory
        for result in rsp.output.results:
            file_name = PurePosixPath(unquote(urlparse(result.url).path)).parts[-1]
            with open('./%s' % file_name, 'wb+') as f:
                f.write(requests.get(result.url).content)
    else:
        print('Failed, status_code: %s, code: %s, message: %s' %
              (rsp.status_code, rsp.code, rsp.message))
