【AI作画】使用stable-diffusion-webui搭建AI作画平台

一、安装配置Anaconda

进入官网下载安装包https://www.anaconda.com/并安装,然后将Anaconda配置到环境变量中。

在这里插入图片描述

打开命令行,依次通过如下命令创建Python运行虚拟环境。

conda env create novelai python==3.10.6
E:\workspace\02_Python\novalai>conda info --envs# conda environments:#
base                  *  D:\anaconda3
novelai                  D:\anaconda3\envs\novelai
conda activate novelai

二、安装CUDA

笔者的显卡为NVIDIA,需安装NVIDIA的开发者工具进入官网https://developer.nvidia.com/,根据自己计算机的系统情况,选择合适的安装包下载安装。

打开安装程序后,依照提示完成安装。

安装完成后,在命令窗口输入如下命令,输出CUDA版本即安装成功。

C:\Users\yefuf>nvcc -V
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c)2005-2022 NVIDIA Corporation
Built on Wed_Sep_21_10:41:10_Pacific_Daylight_Time_2022
Cuda compilation tools, release 11.8, V11.8.89
Build cuda_11.8.r11.8/compiler.31833905_0

三、安装pytorch

进入官网https://pytorch.org/,根据计算机配置选择合适的版本进行安装。这里需要注意的是CUDA的平台选择,先打开NVIDIA控制面板-帮助-系统信息-组件查看CUDA版本,官网上选择的计算平台需要低于计算机的NVIDIA版本。
在这里插入图片描述
配置选择完成后,官网会生成相应的安装命令。
在这里插入图片描述
将安装命令复制出,命令窗口执行安装即可。

conda install pytorch torchvision torchaudio pytorch-cuda=11.6-c pytorch -c nvidia

当查到Pytorch官网推荐的CUDA版本跟你的显卡版本不匹配时,就需要根据官网的CUDA版本找到对应的显卡驱动版本并升级显卡驱动,对应关系可通过https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html查看

四、安装git

进入git官网https://git-scm.com/,下载安装即可。

五、搭建stable-diffusion-webui

进入项目地址https://github.com/AUTOMATIC1111/stable-diffusion-webui,通过git将项目克隆下来。

git clone https://github.com/AUTOMATIC1111/stable-diffusion-webui.git
Cloning into 'stable-diffusion-webui'...

克隆下载扩展库。

克隆完成后,

目录会多如下文件夹:
在这里插入图片描述
下载模型库https://github.com/AUTOMATIC1111/stable-diffusion-webui/wiki/Dependencies,并将下载的

.ckpt

放到

models/Stable-diffusion

文件夹中。模型很大,推荐使用下载器。
在这里插入图片描述
安装项目所需的Python依赖库。

pip install-r requirements.txt

在这里插入图片描述
安装完成之后,运行如下命令,顺利的话,当程序加载完成模型之后,会自动打开

http://127.0.0.1:7860/

显示平台主页。

python launch.py --autolaunch

进入平台的设置页面,选择语言为中文,重启程序之后,即可看到页面显示为中文。

在这里插入图片描述
在界面中输入作画内容的正向提示词(画想要什么特征)和反向提示词(画不想要什么特征),点击生成即可开始自动作画。

在这里插入图片描述
如上述的提示词作出的画如图(由于随机种子不同,生成的画会有差异)。
在这里插入图片描述

六、如何设置提示词

这里建议使用元素法典https://docs.qq.com/doc/DWHl3am5Zb05QbGVs,上面有前人整理好的提示词及效果,以供参考。
在这里插入图片描述

七、可能遇到的问题

1、GitHub访问不了或访问慢

一般为DNS解析问题,需要修改本地host文件,增加配置内容,绕过域名解析,达到加速访问的目的。

访问https://www.ipaddress.com/,分别输入

github.com

github.global.ssl.fastly.net

,获取域名对应的IP地址。
在这里插入图片描述
在这里插入图片描述
打开系统的Host文件,将IP和域名的对应关系配置到Host文件中。
在这里插入图片描述
配置文件内容如下:

140.82.114.4    github.com
199.232.5.194    github.global.ssl.fastly.net

执行命令

ipconfig /flushdns

刷新DNS即可。

2、pip安装依赖库慢或常下载失败

pip安装依赖库时默认选择国外的源,安装速度会非常慢,可以考虑切换为国内源,常用的国内源如下:

阿里云 https://mirrors.aliyun.com/pypi/simple/ 
中国科技大学 https://pypi.mirrors.ustc.edu.cn/simple/ 
豆瓣(douban) https://pypi.douban.com/simple/ 
清华大学 https://pypi.tuna.tsinghua.edu.cn/simple/ 
中国科学技术大学 https://pypi.mirrors.ustc.edu.cn/simple/

在安装依赖库时,可使用

pip install -i 源 空格 安装包名称

进行源的选择,如

pip install -i https://mirrors.aliyun.com/pypi/simple numpy

也可以通过增加配置文件,使安装依赖库时默认选择国内的源,在用户目录下增加

pip.ini

文件。
在这里插入图片描述
在文件中写入如下内容。

[global]timeout=60000
index-url = https://pypi.tuna.tsinghua.edu.cn/simple

[install]
use-mirrors =true
mirrors = https://pypi.tuna.tsinghua.edu.cn

3、安装CLIP时提示Connection was aborted, errno 10053

出错时的错误打印如下:

通过访

pip install ftfy regex tqdm
pip install git+https://github.com/openai/CLIP.git

4、项目启动中提示Connection was reset in connection to github.com

在命令窗口中输入如下命令,然后重新运行程序,但实际操作下来,仍有较大概率在克隆项目的过程中失败。

git config --global http.postBuffer 524288000git config --global http.sslVerify "false"

查看

lauch.py

中的代码可以发现,程序在启动时有对依赖项目进行检查,如项目不存在,则克隆下来。

defprepare_enviroment():
    torch_command = os.environ.get('TORCH_COMMAND',"pip install torch==1.12.1+cu113 torchvision==0.13.1+cu113 --extra-index-url https://download.pytorch.org/whl/cu113")

因此,我们打开

git bash

重新执行上述两条

git

命令,预先将项目克隆下来。

git clone https://github.com/CompVis/taming-transformers.git "repositories\taming-transformers"git clone https://github.com/crowsonkb/k-diffusion.git "repositories\k-diffusion"git clone https://github.com/sczhou/CodeFormer.git "repositories\CodeFormer"git clone https://github.com/salesforce/BLIP.git "repositories\BLIP"

克隆完成之后如图:

由于提示内存溢出,先通过控制面板->所有控制面板项->管理工具->系统信息,查看显卡内存大小。
在这里插入图片描述
官方推荐的显卡内存大小为4GB以上,而笔者的显卡内存只有2GB,显然GPU不符合要求。查看项目的命令选项,发现项目支持CPU计算

尝试构造如下运行参数,

--use-cpu all

使所有模块均使用CPU计算,

--lowram --always-batch-cond-uncond

使用低内存配置选项,程序可以成功运行。

然而,开始作画时提示

错误!如果安装网上的处理方法,将

half

函数在工程中替换为

float

函数,则会出现

device

不匹配问题。

考虑到

--use-cpu

参数可以指定模块,则尝试使工程中的部分模块用CPU计算,其余在可用内存方位内用GPU计算,最终构造参数如下,项目可成功作画。

然而,此方式作画效率非常低,一般每张图片约5-6分钟。当参数设置较大时,会达到数小时。因此如果有条件可以升级计算机的显卡配置,或租赁云服务器效果会更好。
