Ubuntu22.04操纵系统4090显卡电脑本地化摆设DeepSeek

涛声依旧在 · 4 天前

操纵系统：ubuntu22.04
OpenCV版本：OpenCV4.9
IDE:Visual Studio Code
编程语言：C++11

概述

听说最近很火的DeepSeek，就像本地化摆设一个看看，发现本地化摆设很简单，在这儿记录一下。
下载Ollama

看好多指导都是先下载Ollama，起首去Ollama网站，打开网址后如下所示：

点击Download按钮，如下图所示：

按照网页中的指导，去实行一个shell命令：

curl -fsSL https://ollama.com/install.sh | sh

复制代码

命令开始实行，如下所示：

可是，下载速率太慢了！根本没法下载，这个得想办法了，有人会科学下载，我呢是去https://github.com/ollama/ollama下载
打开网页后，看到下图箭头所示，有个Release模块，底下是要下载的文件的版本号

点击版本号，进入下一页，如图所示：

下载上图中箭头所指的文件，然后就期待下载进度了，我下载还是很快的，大概用了几分钟吧。下载的文件名是ollama-linux-amd64.tgz，大小是1.7G。
安装Ollama

由于我是单独下载了安装包，以是必要修改一下ollama提供的安装脚本，把脚本里的下载文件的代码去掉。
实行下面的shell命令，下载安装脚本。

curl -fsSL https://ollama.com/install.sh -o ollama_install.sh

复制代码

ollama_install.sh脚本的内容如下图所示：

#!/bin/sh
# This script installs Ollama on Linux.
# It detects the current operating system architecture and installs the appropriate version of Ollama.

复制代码

然后实行安装脚本，开始安装。

sudo ./ollama_install.sh

复制代码

安装完成后，出现此下图所示的输出，说明安装完成了

输入以下指令，验证是否安装成功：

ollama --version

复制代码

若是出现了版本号的输出，说明安装成功了，如下图所示：

ollama服务设置

先停止ollama服务：

sudo systemctl stop ollama

复制代码

再打开Ollama 服务文件：

sudo vi /etc/systemd/system/ollama.service

复制代码

在[Service]部门下，添加一行内容为Environment=“OLLAMA_HOST=0.0.0.0”，如下所示：

[Unit]
Description=Ollama Service
After=network-online.target
[Service]
ExecStart=/usr/local/bin/ollama serve
User=ollama
Group=ollama
Restart=always
RestartSec=3
Environment="PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin"
# 设置监听地址（关键修改）
Environment="OLLAMA_HOST=0.0.0.0"
[Install]
WantedBy=default.target
~
~
~

复制代码

系统重新加载服务设置文件：

sudo systemctl daemon-reload

复制代码

启动 Ollama 服务：实行sudo systemctl start ollama
，使新的设置生效

sudo systemctl start ollama

复制代码

摆设模型

实行以下指令，开始摆设模型

ollama run deepseek-r1:32b

复制代码

我的显卡是4090，以是我选择32b，

下图是显卡选择参数的表格，仅供参考：

开始摆设中：

这个速率有点慢，可能会有几个小时，得耐心期待。

完成后，会有上图所示的输出信息。
测试

我问了个问题，我很焦虑怎么办
