教你文本生成图片——stablediffusion

今天来点轻松的话题，带大家玩一个用文字生成图片的模型。

相信大家如果关注AIGC领域，对文本生成图片，对Stablefiffusion、DEALL.E应该不陌生。今天给大家介绍的就是基于SD2 finetune出来的一个模型（）

这篇文章不会教大家STABLEDiffusion的原理，也不会去介绍文本生成图的历史，甚至不会让大家知道CLIP。只会带大家想工程师一样用很少的代码批量的产出你想要的图片。为你的软文配图。

先来看几张效果

安装环境

pip install --upgrade diffusers accelerate transformers

开始文本生成图

from diffusers import StableDiffusionPipeline
import torch

model_id = "dreamlike-art/dreamlike-photoreal-2.0"
pipe = StableDiffusionPipeline.from_pretrained(model_id, torch_dtype=torch.float16)
pipe = pipe.to("cuda")

prompt = "3d render, an  soft and smooth appearance cute ant doll stands in the middle, full of sense with blue and white of technology with glow, bright cinematic lighting, gopro, fisheye lens"
image = pipe(prompt).images[0]

image.save("./result.jpg")
'''
#批量prompt生成图片
num = 0
prompt_list = ['a ctue **','...','....']
for prompt in prompt_list:
    image = pipe(prompt).images[0]
    save_file_name = "result{0}.jpg".format(str(num)
    image.save("./result.jpg")
    num+=1
'''

优化promp让图更好看

Start by selecting the medium you want to use for your art, such as photo, digital art, 3d render, painting, etc.
1.开始部分选择你要生成的图片艺术风格，比如：照片、数字艺术、3d渲染、优化等等

Next, describe what you want to generate. For better results be specific and use descriptive language. For example, instead of saying "a castle" you could say "a medieval castle on a cliff, storm clouds, restless ocean".
2.接着你要描述你要生成的具体物品，为了得到更好效果最好用描述性形容性词汇，例如，与其说“一座城堡”，不如说“悬崖上的中世纪城堡、暴风云、动荡的海洋”

To make your prompt even more specific, you can add modifiers such as "dark cinematic lighting" or "highly detailed, intricate, bokeh". This will help the AI generate art that is more in line with your vision.
3.为了让你的提示更加具体，你可以添加修饰符，例如“暗色系光照”或“细节很详细、复杂、散景”。这将帮助 AI 生成更符合你意愿的作品。

If you have any particular artists in mind, you can add their names to your prompt. Some popular artists include Greg Rutkowski, Artgerm, Alphonse Mucha, and Zdzislaw Beksinski. Check out these links for a list of supported artists and some examples of their art:
4.如果你有特定的艺术家或艺术手法你可以加上去，这样生成图片会更符合你要求

3d render, an cute ant doll with blue and white of technology glow ，soft and smooth appearance stands in the middle, bright cinematic lighting, gopro, romatic, 4k hd wallpaper, conceptart

3d render, an cute ant doll with blue and white of technology glow ，soft and smooth appearance stands in the middle, bright cinematic lighting, gopro, romatic, 4k hd wallpaper, bright illustration,cuteart

小结

今天就带大家用代码方式批量做图片生成。

大家一定发现这东西拿到只能生成某个物体吗，能不能生成一些背景。

有没办法让生成的物体不变，在增加一些元素会改变一些图片内容。

现在生成的方式太随机了，同一句prompt生成的图片都会出现差异，有没办法解决

还有就是有没可能批量生成风格稳定的图

有没办法自动的生成prompt生成高质量的图片

大家先别急下面几篇文章会一一给你解答。
