基于 https://github.com/AUTOMATIC1111/stable-diffusion-webui

本文记录于 2023-08-20，以下方法可能失效，请审慎参考

1. 安装

注意升级 git 到2.x版本 git --version
yum install zlib-devel + https://juejin.cn/post/7071910670056292389

https://zhuanlan.zhihu.com/p/639164507

2. 下载模型

https://huggingface.co/docs/huggingface_hub/main/en/guides/download

yum install git-lfs
git lfs install

python代码下载模型

https://huggingface.co/stabilityai/stable-diffusion-2-1/tree/main

# pip install huggingface_hub
from huggingface_hub import snapshot_download, hf_hub_download
snapshot_download(repo_id="stabilityai/stable-diffusion-2-1", cache_dir='/your_path/')

3. 解决报错

• ImportError: cannot import name 'rank_zero_only' from 'pytorch_lightning.utilities.distributed'

https://github.com/AUTOMATIC1111/stable-diffusion-webui/discussions/4111

from pytorch_lightning.utilities.rank_zero import rank_zero_only

• ImportError: cannot import name 'get_device' from 'basicsr.utils.misc'

https://github.com/sczhou/CodeFormer/issues/193

# basicsr\utils\misc.py
import torch
def get_device():
    if torch.cuda.is_available():
        return torch.device("cuda")
    else:
        return torch.device("cpu")

def gpu_is_available():
        return torch.cuda.is_available()

4. UI 模式

在Centos服务器部署的 SD

现在在本地windows使用cmd命令，进行端口转发

ssh-keygen -R ip
ssh -L 7860:localhost:7860 user@ip

或者 使用 mobaxterm 启动隧道 tunneling

• 在服务器上启动 python launch.py

$ python launch.py

然后在本地浏览器打开 http://localhost:7860/，即可使用远程的SD

5. API模式

https://zhuanlan.zhihu.com/p/629845245

• sh webui.sh --nowebui --xformers
• 或者 后台运行 nohup python launch.py --nowebui --xformers > nohup.out 2>&1 &

(sd) [web@bdp-measure3 stable-diffusion-webui]$ sh webui.sh --nowebui --xformers
