模型信息 Model Information

我们使用 AltCLIP-m9，基于 Stable Diffusion 训练了双语Diffusion模型，训练数据来自 WuDao数据集和 LAION 。

我们的版本在多语言对齐方面表现非常出色，是目前市面上开源的最强多语言版本，保留了原版stable diffusion的大部分能力，并且在某些例子上比有着比原版模型更出色的能力。

AltDiffusion-m9 模型由名为 AltCLIP-m9 的多语 CLIP 模型支持，该模型也可在本项目中访问。您可以阅读此教程了解更多信息。

We used AltCLIP-m9, and trained a bilingual Diffusion model based on Stable Diffusion, with training data from WuDao dataset and LAION.

Our model performs well in aligning multilanguage and is the strongest open-source version on the market today, retaining most of the stable diffusion capabilities of the original, and in some cases even better than the original model.

AltDiffusion-m9 model is backed by a multilingual CLIP model named AltCLIP-m9, which is also accessible in FlagAI. You can read this tutorial for more information.

示例 Example

🧨Diffusers Example

AltDiffusion-m9 已被添加到 🧨Diffusers!

我们的代码示例已放到colab上，欢迎使用。

您可以在此处查看文档页面。

以下示例将使用fast DPM 调度程序生成图像, 在V100 上耗时大约为 2 秒。

You can run our diffusers example through here in colab.

You can see the documentation page here.

The following example will use the fast DPM scheduler to generate an image in ca. 2 seconds on a V100.

First you should install diffusers main branch and some dependencies:

pip install git+https://github.com/huggingface/diffusers.git torch transformers accelerate sentencepiece

then you can run the following example:

python

from diffusers import AltDiffusionPipeline, DPMSolverMultistepScheduler
import torch

pipe = AltDiffusionPipeline.from_pretrained("BAAI/AltDiffusion-m9", torch_dtype=torch.float16, revision="fp16")
pipe = pipe.to("cuda")

pipe.scheduler = DPMSolverMultistepScheduler.from_config(pipe.scheduler.config)

prompt = "黑暗精灵公主，非常详细，幻想，非常详细，数字绘画，概念艺术，敏锐的焦点，插图"
# or in English:
# prompt = "dark elf princess, highly detailed, d & d, fantasy, highly detailed, digital painting, trending on artstation, concept art, sharp focus, illustration, art by artgerm and greg rutkowski and fuji choko and viktoria gavrilenko and hoang lap"

image = pipe(prompt, num_inference_steps=25).images[0]
image.save("./alt.png")
