前言
随着人工智能的不断发展，AI绘图热兴起，我也想加入到AI绘图大潮中。
一、Stable Diffusion WebUI适配三类芯片
此模型支持三类GPU芯片
- NVidia (re***mended)
- AMD GPUs.
- Intel CPUs, Intel GPUs (bothintegrated and discrete) （我的mac属于此情况）
二、安装
说明：期间需要访问外网，自行实现巧妙上网
1.安装git、conda等
brew install cmake protobuf rust python@3.10 git wget miniconda
2.选定目录及下载Github远程仓库文件
mkdir SDW
cd SDW
git clone git@github.***:openvinotoolkit/stable-diffusion-webui.git
3.创建conda虚拟环境
创建虚拟环境
conda env create -p /Users/zhaoyao/Downloads/SDW/stable-diffusion-webui/automatic -f /Users/zhaoyao/Downloads/SDW/stable-diffusion-webui/environment-wsl2.yaml
最后创建完成后显示如下：
# To activate this environment, use
#
# $ conda activate /Users/zhaoyao/Downloads/SDW/stable-diffusion-webui/automatic
#
# To deactivate an active environment, use
#
# $ conda deactivate
激活环境
conda activate /Users/zhaoyao/Downloads/SDW/stable-diffusion-webui/automatic
4.安装依赖
cd stable-diffusion-webui
pip install -r requirements.txt
pip速度慢需添加国内pip源
cd ~
mkdir .pip
cd .pip
touch pip.conf
在pip.conf文件中，添加以下内容：
[global]
index-url = https://pypi.doubanio.***/simple/
trusted-host = pypi.doubanio.***
5.运行
还有未安装的依赖在此步骤执行中会一次安装，当然有报错需要一次解决。
英特尔CPU+GPU的场景执行前环境要生效如下内容：
export PYTORCH_TRACING_MODE=TORCHFX
export ***MANDLINE_ARGS="--skip-torch-cuda-test --precision full --no-half"
./webui.sh
6.问题处理
运行./webui.sh会有很多报错
缺openai模块等
OSError: Can't load tokenizer for 'openai/clip-vit-large-patch14'. If you were trying to load it from 'https://huggingface.co/models', make sure you don't have a local directory with the same name. Otherwise, make sure 'openai/clip-vit-large-patch14' is the correct path to a directory containing all relevant files for a CLIPTokenizer tokenizer.
手动git clone
可直接git clone
可以指定git代理实现
#指定git代理
git config --global https.proxy socks5://127.0.0.1:1088
或
git config --global https.proxy https://127.0.0.1:1088
#取消git代理
git config --global --unset https.proxy
例如：
git clone https://huggingface.co/openai/clip-vit-large-patch14
或
git clone git@hf.co:openai/clip-vit-large-patch14
类似的v1-5-pruned-emaonly.safetensors模型获取失败
https://huggingface.co/runwayml/stable-diffusion-v1-5/resolve/main/v1-5-pruned-emaonly.safetensors
此文件较大有4G多，建议通过从源网站下载到云盘，再从云盘下载到本地，然后让入目标文件夹如：stable-diffusion-uebul/models/Stable-diffusion/
RuntimeError: “LayerNormKernelImpl” not implemented for 'Half’等
RuntimeError: "LayerNormKernelImpl" not implemented for 'Half'
/Users/zhaoyao/Downloads/SDW/stable-diffusion-webui/venv/lib/python3.10/site-packages/torch/nn/functional.py", line 2515, in layer_norm
RuntimeError: "addmm_impl_cpu_" not implemented for 'Half'
/Users/zhaoyao/Downloads/SDW/stable-diffusion-webui/venv/lib/python3.10/site-packages/torch/nn/modules/linear.py", line 114, in forward
那么执行时添加如下参数：
./webui.sh --precision full --no-half
正常运行sdw的的话会自动访问http://127.0.0.1:7860/
命令行显示类似如下：
浏览器显示如下：
注意选择支持intel GPU的script，OpenVINO™ A***eleration Script
绘图时报错
类似如下报错
报错显示如下：
OSError: We couldn't connect to 'https://huggingface.co' to load this file, couldn't find it in the cached files and it looks like ***pVis/stable-diffusion-safety-checker is not the path to a directory containing a file named config.json. Checkout your inter*** connection or see how to run the library in offline mode at 'https://huggingface.co/docs/transformers/installation#offline-mode'.

很显然是绘图时需要访问huggingface.co下载模块
考虑直接添加代理的方式，因为不可能每次画图每次需要下载模块的时候每次手动下载
修改webu.sh
在此文件后追加代理
proxy='socks5://127.0.0.1:1088'
export http_proxy=$proxy
export https_proxy=$proxy
export no_proxy="localhost, *.local, 127.0.0.1, ::1, 192.168.*.*, 10.*.*.*, 172.16-31.*.*, *.baidu.****, *.bilibili.****, *.****, *.***.****, *.csdn.****, *.51cto*, *tencent*, *qq.****, *weixin*, *ali*, *dingding*, *huawei*, *xunlei*, *tonghuashun*, *dongfangcaifu*, *i4tool*, *163.****, *doubanio.****, *douban*, *youku*"
绘图时会有如下显示：
绘图结束显示
