准备工作
- 下载源码 text-generation-Webui
- 下载模型 chinese-alpaca-2-7b-hf下载完成的模型需要放置在项目下的models目录下
- 安装conda Free Download | Anaconda
- 安装python python
- 设置环境变量
- 下载最新的显卡驱动
英伟达2060显卡驱动需要与自己显卡匹配
- 查看显卡驱动版本
部署工作
- 创建conda环境
conda create -n textgen python=3.10.9
- 初始化
conda init
- 激活
conda activate textgen
- 安装pytorch注意此处安装的版本需要与显卡对应否则会报各种错误
pip install torch torchvision torchaudio -f https://download.pytorch.org/whl/cu121/torch_stable.html
cu121表示对应显卡版本12,可以从官网查看,这个很关键
- 安装项目的依赖
pip install-r requirements.txt
- 加载模型并启动
python server.py --model chinese-alpaca-2-7b --chat
- 加载成功后显示
- 打开浏览器输入对应的地址
9. 设置模型参数
踩坑记录
- ‘conda’ 不是内部或外部命令,也不是可运行的程序 或批处理文件。
没有安装conda导致,且需要配置环境变量
- 版本太高
Channels: - defaultsPlatform: win-64Collecting package metadata (repodata.json): doneSolving environment: failedPackagesNotFoundError: The following packages are not available from current channels: - python=3.12.1*Current channels: - defaultsTo search for alternate channels that may provide the conda package you'relooking for, navigate to https://anaconda.organd use the search bar at the top of the page.``````这个错误是因为在当前Conda默认的渠道(
defaults)中找不到名为
python且版本为
3.12.1的包。这可能是因为3.12.1版本的Python还没有被添加到默认的Conda渠道中。
- conda需要先初始化

不要用cmd ,用Powershell
- 加载模型名称错误
拼写正确即可
- 安装了错误的torch,不支持gpu计算
运行 python -c "impot torch;print(torch.cuda.is_available()) 判断返回值,false表示不支持,true表示支持,卸载重装"
- 前方高能,这里有个大坑
之前看其他博主安装时通过start_windows.bat 安装,网页启动后加载模型然后报 ExLlama这个模块找不到的错误,于是乎看到国内的Gitee上的项目说exllama需要安装微软的编译器环境及英伟达的CUDA驱动(这个驱动安装包3G),按照操作走流程。最终还是找不到这个模块,于是放弃了,采用conda的方式进行安装,安装的时候CUDA驱动一直没有删除,直到看到这里
通过mvcc -version 命令查看显卡CUDA驱动版本11.8,下载了对应的torch版本对应的为11.8
该版本的torch显示支持显卡驱动了,启动报错显示找不到模块。
说明11.8的torch与CUDA 11.8 不匹配。卸载了11.8的torch和删除了CUDA驱动,后重写安装。torch用官网的12.1 ,驱动下载最新的12(600MB)再次启动才成功。
- 卸载
- 安装12.1torch
- 此时CUDA驱动(3GB)还没有卸载,安装了最新的torch启动报错提示版本低
- 从官网下载通用版的驱动(600MB)后再次执行,启动成功! 参考文献:(https://bbs.huaweicloud.com/blogs/412544)
