部署自己的对话大模型，使用Ollama + Qwen2 +FastGPT 实现

部署资源

AUTODL 使用最小3080Ti 资源，cuda > 12.0
使用云服务器，部署fastGPT oneAPI，M3E 模型

操作步骤

配置代理
export HF_ENDPOINT=https://hf-mirror.com
下载qwen2模型 - 如何下载huggingface
huggingface-cli download Qwen/Qwen2-7B-Instruct-GGUF qwen2-7b-instruct-q5_k_m.gguf --local-dir . --local-dir-use-symlinks False

创建模型文件

FROM qwen2-7b-instruct-q5_k_m.gguf

打开oneapi http://ip:3001, 初始密码 root 1234，配置qwen2 模型以及M3E模型
点击测试
- 注：M3E 点击测试后提示404是正常的
重启fastgpt 和 oneapi
docker-compose restart fastgpt oneapi
在fastgpt 中创建一个应用进行测试
大功告成！！！
