Fastgpt配合chatglm+m3e或ollama+m3e搭建个人知识库

news 2025/9/14 10:34:16

概述：

人工智能大语言模型是近年来人工智能领域的一项重要技术，它的出现标志着自然语言处理领域的重大突破。这些模型利用深度学习和大规模数据训练，能够理解和生成人类语言，为各种应用场景提供了强大的文本处理能力。AI大语言模型的技术原理主要基于深度学习和自然语言处理技术，通过自监督学习和大规模文本数据的预训练来学习语言的表示。训练完成后，可以通过微调等方法，将模型应用于特定的任务和应用场景。
未来，AI大语言模型有望在更多领域发挥作用，包括自然语言理解、文本生成、对话系统、语言翻译等。它们可以用于自动摘要、文档生成、智能客服、智能问答等多种应用场景，为用户提供了更加智能和个性化的服务。
本文为学习大语言模型及FastGPT部署的学习笔记。通过直接部署**ChatGML3大语言模型**或**OLLAMA模型管理工具**配合FastGPT私有化搭建知识库。其中**one-api**、**fastgpt**是两种方法都需要部署的，其他的更建议使用ollama直接进行部署，切换模型方便快捷，易于管理。

硬件要求

以下配置仅作参考
**chatglm3-6b+m3e：**3060 12 ↑
**qwen:4b+m3e：**3060 12 ↑
**qwen:2b+m3e：**1660 6g↑
总结：模型量级越大所需显卡性能越高，过小的量级的大模型在低端cpu亦可运行，只是推理的精准度很差，更不能配合m3e向量模型进行推理，速度会非常慢。

conda update --all

创建虚拟环境

conda create --name windows_chatglm3-6b python=3.11 -y

激活并进入虚拟环境

conda activate windows_chatglm3-6b

安装pytorch

cmd:nvidia-smi查看最高支持的 CUDA Version，我的是12.2

安装pytorch

PyTorch是一个开源的Python机器学习库，基于Torch，用于自然语言处理等应用程序。PyTorch既可以看作加入了GPU支持的numpy，同时也可以看成一个拥有自动求导功能的强大的深度神经网络。

在 https://pytorch.org/get-started/locally/ 查询自己电脑需要执行的命令
在conda虚拟环境内执行以下命令安装pytorch

conda install pytorch torchvision torchaudio pytorch-cuda=12.1 -c pytorch -c nvidia

chatglm3环境搭建(非ollama模式)

模型及DEMO下载

一共需要下载两个模型chatglm3 及m3e

chatglm3下载

模型地址：https://modelscope.cn/models/ZhipuAI/chatglm3-6b/summary
下载方法：git
下载时间较久，耐心等待

git lfs install
git clone https://www.modelscope.cn/ZhipuAI/chatglm3-6b.git

m3e-base下载

git clone https://www.modelscope.cn/Jerry0/m3e-base.git

官方ChatGLM3 DEMO下载

地址：https://github.com/THUDM/ChatGLM3
下载方法：git

git clone https://github.com/THUDM/ChatGLM3

配置及运行

进入刚刚clone的 ChatGLM3/openai_api_demo文件夹
打开api_server.py的python文件
代码拉倒最下方

覆盖if name == “main”:方法内的代码如下：

其中一些地方需要修改，`tokenizer`及`model`的地址对应的是[chatglm3](#eB5m3)的下载地址，`embedding_model`的地址对应的是[m3e](#FHYRP)的下载地址，`port`可根据个人需要自行配置

tokenizer = AutoTokenizer.from_pretrained("E:\Work\HaoQue\FastGPT\models\chatglm3-6B-32k-int4", trust_remote_code=True)model = AutoModel.from_pretrained("E:\Work\HaoQue\FastGPT\models\chatglm3-6B-32k-int4", trust_remote_code=True, device_map="auto").eval()
# load Embeddingembedding_model = SentenceTransformer("E:\Work\HaoQue\FastGPT\models\m3e-base", trust_remote_code=True, device="cuda")uvicorn.run(app, host='0.0.0.0', port=8000, workers=1)

回到ChatGLM3根目录进入刚刚创建的windows_chatglm3-6bconda 虚拟环境
cmd运行pip install -r requirements.txt安装依赖
耐心等待安装完成
完成后运行通过python运行 python openai_api_demo/api_server.py
查看运行结果，以下为运行成功。

ollama环境搭建

ollama程序下载及模型安装安装

下载：https://ollama.com/download
安装直接下一步
安装完成后进入cmd 输入 ollama -v验证是否成功

通过ollama进行模型下载

模型列表：https://ollama.com/library
这里以qwen:1.8b为例
cmd运行 ollama run qwen:1.8b
耐心等待下载即可
下载完成模型会自动启动，无需其他操作

m3e环境搭建（ollama模式）

使用docker进行部署，docker安装在此不做介绍。

docker run -d --name m3e -p 6008:6008 --gpus all -e sk-key=123321  registry.cn-hangzhou.aliyuncs.com/fastgpt_docker/m3e-large-api

one-api环境部署及配置

使用docker进行部署，docker安装在此不做介绍。

docker run --name one-api -d --restart always -p 3000:3000 -e TZ=Asia/Shanghai -v /home/ubuntu/data/one-api:/data justsong/one-api

然后访问[http://localhost:3000/](http://localhost:3001/)端口为docker run 时候-p的端口，

登陆初始账号用户名为 root，密码为 123456。
登陆后来到渠道页面添加渠道，此步骤添加的是大语言模型
如果你是通过ollama运行的大模型，则需要再次添加新渠道，本次添加m3e渠道
新建令牌
新建令牌后，复制令牌sdk备用

fastgpt环境搭建

参考文档：https://doc.fastai.site/docs/development/docker/

非 Linux 环境或无法访问外网环境，可手动创建一个目录，并下载下面2个链接的文件: docker-compose.yml,config.json

注意: docker-compose.yml 配置文件中 Mongo 为 5.x，部分服务器不支持，需手动更改其镜像版本为 4.4.24（需要自己在docker hub下载，阿里云镜像没做备份）

config.json配置文件修改
1. 打开下载的config.json
2. 复制并替换**llmModels**数组中的第一组数据，修改model和name属性为你部署的模型属性，其他可以不做修改

    {"model": "gemma:2b","name": "gemma:2b","maxContext": 16000,"avatar": "/imgs/model/openai.svg","maxResponse": 4000,"quoteMaxToken": 13000,"maxTemperature": 1.2,"charsPointsPrice": 0,"censor": false,"vision": false,"datasetProcess": true,"usedInClassify": true,"usedInExtractFields": true,"usedInToolCall": true,"usedInQueryExtension": true,"toolChoice": true,"functionCall": true,"customCQPrompt": "","customExtractPrompt": "","defaultSystemChatPrompt": "","defaultConfig": {}},

如果你是ollama部署的大模型
1. 打开下载的config.json
2. 在**vectorModels**数组中添加以下数据

    {"model": "m3e","name": "M3E","inputPrice": 0,"outputPrice": 0,"defaultToken": 700,"maxToken": 1800,"weight": 100}

打开docker-compose.yml
注释掉mysql 及 oneapi相关配置
**启动容器 **

在 docker-compose.yml 同级目录下执行。请确保docker-compose版本最好在2.17以上，否则可能无法执行自动化命令。

# 启动容器
docker-compose up -d
# 等待10s，OneAPI第一次总是要重启几次才能连上Mysql
sleep 10
# 重启一次oneapi(由于OneAPI的默认Key有点问题，不重启的话会提示找不到渠道，临时手动重启一次解决，等待作者修复)
docker restart oneapi

访问 FastGPT

目前可以通过 ip:3000 直接访问(注意防火墙)。登录用户名为 root，密码为docker-compose.yml环境变量里设置的 DEFAULT_ROOT_PSW。
如果需要域名访问，请自行安装并配置 Nginx。
首次运行，会自动初始化 root 用户，密码为 1234

报huggingface-hub的错

pip install huggingface-hub==0.20.3

显存不足尝试设置环境变量

set PYTORCH_CUDA_ALLOC_COFF=expandable_segments:True
再次运行python api_server.py（经测试无用）
torch.cuda.OutOfMemoryError: CUDA out of memory. Tried to allocate 108.00 MiB. GPU 0 has a total capacity of 6.00 GiB of which 0 bytes is free. Of the allocated memory 12.31 GiB is allocated by PyTorch, and 1.27 MiB is reserved by PyTorch but unallocated. If reserved but unallocated memory is large try setting PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True to avoid fragmentation.

api_server.py整体

"""
This script implements an API for the ChatGLM3-6B model,
formatted similarly to OpenAI's API (https://platform.openai.com/docs/api-reference/chat).
It's designed to be run as a web server using FastAPI and uvicorn,
making the ChatGLM3-6B model accessible through OpenAI Client.Key Components and Features:
- Model and Tokenizer Setup: Configures the model and tokenizer paths and loads them.
- FastAPI Configuration: Sets up a FastAPI application with CORS middleware for handling cross-origin requests.
- API Endpoints:- "/v1/models": Lists the available models, specifically ChatGLM3-6B.- "/v1/chat/completions": Processes chat completion requests with options for streaming and regular responses.- "/v1/embeddings": Processes Embedding request of a list of text inputs.
- Token Limit Caution: In the OpenAI API, 'max_tokens' is equivalent to HuggingFace's 'max_new_tokens', not 'max_length'.
For instance, setting 'max_tokens' to 8192 for a 6b model would result in an error due to the model's inability to output
that many tokens after accounting for the history and prompt tokens.
- Stream Handling and Custom Functions: Manages streaming responses and custom function calls within chat responses.
- Pydantic Models: Defines structured models for requests and responses, enhancing API documentation and type safety.
- Main Execution: Initializes the model and tokenizer, and starts the FastAPI app on the designated host and port.Note:This script doesn't include the setup for special tokens or multi-GPU support by default.Users need to configure their special tokens and can enable multi-GPU support as per the provided instructions.Embedding Models only support in One GPU.Running this script requires 14-15GB of GPU memory. 2 GB for the embedding model and 12-13 GB for the FP16 ChatGLM3 LLM."""import os
