【ai技术】（4）：在树莓派上，使用qwen0.5b大模型+chatgptweb，搭建本地大模型聊天环境，速度飞快，非常不错！

2，下载镜像 raspberry-pi-os-64-bit

项目地址：

3，在raspberrypi 4 上安装docker和docker-compose

https://docs.docker.com/engine/install/debian/

设置docker 的源：

# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/debian/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc# Add the repository to Apt sources:
echo \"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/debian \$(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

替换成 阿里 源：

sed -i 's/deb.debian.org/mirrors.aliyun.com/g' /etc/apt/sources.list

安装docker 和 docker-compose 命令

 sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

经过漫长等等，就可以安装成功了：

Docker version 26.0.0, build 2ae903e

特别注意是 docker-compose-linux-armv7 版本，linux版本。

sudo curl -SL https://mirror.ghproxy.com/https://github.com/docker/compose/releases/download/v2.25.0/docker-compose-linux-armv7 -o /usr/local/bin/docker-compose#然后授权
sudo chmod 755 /usr/local/bin/docker-compose
docker-compose -v
Docker Compose version v2.25.0

建议切换成百度的镜像：

{"registry-mirrors": [ "https://mirror.baidubce.com" ] 
}

4，下载项目ollama-chatgpt-web并启动

git clone https://gitee.com/fly-llm/ollama-chatgpt-web.git
cd ollama-chatgpt-web
docker-compose up -d
