# 贡献指南
|
||||
|
||||
欢迎！我们是一个非常友好的社区，非常高兴您想要帮助我们让这个应用程序变得更好。但是，请您遵循一些通用准则以保持组织有序。
|
||||
|
||||
1. 确保为您要修复的错误或要添加的功能创建了一个[问题](https://github.com/imClumsyPanda/langchain-ChatGLM/issues)，尽可能保持它们小。
|
||||
2. 请使用 `git pull --rebase` 来拉取和衍合上游的更新。
|
||||
3. 将提交合并为格式良好的提交。在提交说明中单独一行提到要解决的问题，如`Fix #<bug>`（有关更多可以使用的关键字，请参见[将拉取请求链接到问题](https://docs.github.com/en/issues/tracking-your-work-with-issues/linking-a-pull-request-to-an-issue)）。
|
||||
4. 推送到`dev`。在说明中提到正在解决的问题。

# Contribution Guide
|
||||
|
||||
Welcome! We're a pretty friendly community, and we're thrilled that you want to help make this app even better. However, we ask that you follow some general guidelines to keep things organized around here.
|
||||
|
||||
1. Make sure an [issue](https://github.com/imClumsyPanda/langchain-ChatGLM/issues) is created for the bug you're about to fix, or feature you're about to add. Keep them as small as possible.

|
||||
从 `0.1.x` 升级过来的用户请注意，需要按照[开发部署](README.md#3.-开发部署)过程操作，将现有知识库迁移到新格式，具体见[知识库初始化与迁移](docs/INSTALL.md#知识库初始化与迁移)。
|
||||
|
||||
## 快速上手
|
||||
### `0.2.0` 版本与 `0.1.x` 版本区别
|
||||
|
||||
### 1. 环境配置
|
||||
1. 使用 [FastChat](https://github.com/lm-sys/FastChat) 提供开源 LLM 模型的 API，以 OpenAI API 接口形式接入，提升 LLM 模型加载效果；
|
||||
2. 使用 [langchain](https://github.com/langchain-ai/langchain) 中已有 Chain 的实现，便于后续接入不同类型 Chain，并将对 Agent 接入开展测试；
|
||||
3. 使用 [FastAPI](https://github.com/tiangolo/fastapi) 提供 API 服务，全部接口可在 FastAPI 自动生成的 docs 中开展测试，且所有对话接口支持通过参数设置流式或非流式输出；
|
||||
4. 使用 [Streamlit](https://github.com/streamlit/streamlit) 提供 WebUI 服务，可选是否基于 API 服务启动 WebUI，增加会话管理，可以自定义会话主题并切换，且后续可支持不同形式输出内容的显示；
|
||||
5. 项目中默认 LLM 模型改为 [THUDM/chatglm2-6b](https://huggingface.co/THUDM/chatglm2-6b)，默认 Embedding 模型改为 [moka-ai/m3e-base](https://huggingface.co/moka-ai/m3e-base)，文件加载方式与文段划分方式也有调整，后续将重新实现上下文扩充，并增加可选设置；
|
||||
6. 项目中扩充了对不同类型向量库的支持，除支持 [FAISS](https://github.com/facebookresearch/faiss) 向量库外，还提供 [Milvus](https://github.com/milvus-io/milvus), [PGVector](https://github.com/pgvector/pgvector) 向量库的接入；
|
||||
7. 项目中搜索引擎对话，除 Bing 搜索外，增加 DuckDuckGo 搜索选项，DuckDuckGo 搜索无需配置 API Key，在可访问国外服务环境下可直接使用。
|
||||
|
||||
+ 首先，确保你的机器安装了 Python 3.8 - 3.11 (我们强烈推荐使用 Python3.11)。
|
||||
---
|
||||
|
||||
```
|
||||
$ python --version
|
||||
Python 3.11.7
|
||||
```
|
||||
## 模型支持
|
||||
|
||||
接着，创建一个虚拟环境，并在虚拟环境内安装项目的依赖
|
||||
本项目中默认使用的 LLM 模型为 [THUDM/chatglm2-6b](https://huggingface.co/THUDM/chatglm2-6b)，默认使用的 Embedding 模型为 [moka-ai/m3e-base](https://huggingface.co/moka-ai/m3e-base) 为例。
|
||||
|
||||

|
||||
，然后运行
|
||||
本项目已在 Python 3.8.1 - 3.10，CUDA 11.7 环境下完成测试。已在 Windows、ARM 架构的 macOS、Linux 系统中完成测试。
|
||||
|
||||
### 1. 开发环境准备
|
||||
|
||||
参见 [开发环境准备](docs/INSTALL.md)。
|
||||
|
||||
**请注意：** `0.2.0` 及更新版本的依赖包与 `0.1.x` 版本依赖包可能发生冲突，强烈建议新建环境后重新安装依赖包。
|
||||
|
||||
### 2. 下载模型至本地
|
||||
|
||||
如需在本地或离线环境下运行本项目，需要首先将项目所需的模型下载至本地，通常开源 LLM 与 Embedding 模型可以从 [HuggingFace](https://huggingface.co/models) 下载。
|
||||
|
||||
以本项目中默认使用的 LLM 模型 [THUDM/chatglm2-6b](https://huggingface.co/THUDM/chatglm2-6b) 与 Embedding 模型 [moka-ai/m3e-base](https://huggingface.co/moka-ai/m3e-base) 为例：
|
||||
|
||||
下载模型需要先[安装Git LFS](https://docs.github.com/zh/repositories/working-with-files/managing-large-files/installing-git-large-file-storage)，然后运行
|
||||
|
||||
```Shell
|
||||
$ git lfs install
|
||||
$ git clone https://huggingface.co/THUDM/chatglm3-6b
|
||||
$ git clone https://huggingface.co/BAAI/bge-large-zh
|
||||
$ git clone https://huggingface.co/THUDM/chatglm2-6b
|
||||
|
||||
$ git clone https://huggingface.co/moka-ai/m3e-base
|
||||
```
|
||||
|
||||
### 3. 初始化知识库和配置文件
|
||||
### 3. 设置配置项
|
||||
|
||||
按照下列方式初始化自己的知识库和简单的复制配置文件
|
||||
复制模型相关参数配置模板文件 [configs/model_config.py.example](configs/model_config.py.example) 存储至项目路径下 `./configs` 路径下，并重命名为 `model_config.py`。
|
||||
|
||||
```shell
|
||||
$ python copy_config_example.py
|
||||
$ python init_database.py --recreate-vs
|
||||
```
|
||||
复制服务相关参数配置模板文件 [configs/server_config.py.example](configs/server_config.py.example) 存储至项目路径下 `./configs` 路径下，并重命名为 `server_config.py`。
|
||||
|
||||
### 4. 一键启动
|
||||
在开始执行 Web UI 或命令行交互前，请先检查 `configs/model_config.py` 和 `configs/server_config.py` 中的各项模型参数设计是否符合需求：
|
||||
|
||||
按照以下命令启动项目
|
||||
- 请确认已下载至本地的 LLM 模型本地存储路径写在 `llm_model_dict` 对应模型的 `local_model_path` 属性中，如:
|
||||
|
||||
```python
|
||||
llm_model_dict={
|
||||
"chatglm2-6b": {
|
||||
"local_model_path": "/Users/xxx/Downloads/chatglm2-6b",
|
||||
"api_base_url": "http://localhost:8888/v1", # "name"修改为 FastChat 服务中的"api_base_url"
|
||||
"api_key": "EMPTY"
|
||||
},
|
||||
}
|
||||
```
|
||||
|
||||
- 请确认已下载至本地的 Embedding 模型本地存储路径写在 `embedding_model_dict` 对应模型位置，如：
|
||||
|
||||
```python
|
||||
embedding_model_dict = {
|
||||
"m3e-base": "/Users/xxx/Downloads/m3e-base",
|
||||
}
|
||||
```
|
||||
|
||||
如果你选择使用OpenAI的Embedding模型，请将模型的 ``key``写入 `embedding_model_dict`中。使用该模型，你需要能够访问OpenAI官的API，或设置代理。
|
||||
|
||||
### 4. 知识库初始化与迁移
|
||||
|
||||
当前项目的知识库信息存储在数据库中，在正式运行项目之前请先初始化数据库（我们强烈建议您在执行操作前备份您的知识文件）。
|
||||
|
||||
- 如果您是从 `0.1.x` 版本升级过来的用户，针对已建立的知识库，请确认知识库的向量库类型、Embedding 模型与 `configs/model_config.py` 中默认设置一致，如无变化只需以下命令将现有知识库信息添加到数据库即可：
|
||||
|
||||
```shell
|
||||
$ python init_database.py
|
||||
```
|
||||
- 如果您是第一次运行本项目，知识库尚未建立，或者配置文件中的知识库类型、嵌入模型发生变化，或者之前的向量库没有开启 `normalize_L2`，需要以下命令初始化或重建知识库：
|
||||
|
||||
```shell
|
||||
$ python init_database.py --recreate-vs
|
||||
```
|
||||
|
||||
### 5. 一键启动API 服务或 Web UI
|
||||
|
||||
#### 5.1 启动命令
|
||||
|
||||
一键启动脚本 startup.py,一键启动所有 Fastchat 服务、API 服务、WebUI 服务，示例代码：
|
||||
|
||||
```shell
|
||||
$ python startup.py -a
|
||||
```
|
||||
|
||||
### 5. 启动界面示例
|
||||
并可使用 `Ctrl + C` 直接关闭所有运行服务。如果一次结束不了，可以多按几次。
|
||||
|
||||
如果正常启动，你将能看到以下界面
|
||||
可选参数包括 `-a (或--all-webui)`, `--all-api`, `--llm-api`, `-c (或--controller)`, `--openai-api`,
|
||||
`-m (或--model-worker)`, `--api`, `--webui`，其中：
|
||||
|
||||
1. FastAPI Docs 界面
|
||||
- `--all-webui` 为一键启动 WebUI 所有依赖服务；
|
||||
- `--all-api` 为一键启动 API 所有依赖服务；
|
||||
- `--llm-api` 为一键启动 Fastchat 所有依赖的 LLM 服务；
|
||||
- `--openai-api` 为仅启动 FastChat 的 controller 和 openai-api-server 服务；
|
||||
- 其他为单独服务启动选项。
|
||||
|
||||
|
||||
#### 5.2 启动非默认模型
|
||||
|
||||
2. Web UI 启动界面示例：
|
||||
若想指定非默认模型，需要用 `--model-name` 选项，示例：
|
||||
|
||||
```shell
|
||||
$ python startup.py --all-webui --model-name Qwen-7B-Chat
|
||||
```
|
||||
|
||||
更多信息可通过 `python startup.py -h`查看。
|
||||
|
||||
#### 5.3 多卡加载
|
||||
|
||||
项目支持多卡加载，需在 startup.py 中的 create_model_worker_app 函数中，修改如下三个参数:
|
||||
|
||||
```python
|
||||
gpus=None,
|
||||
num_gpus=1,
|
||||
max_gpu_memory="20GiB"
|
||||
```
|
||||
|
||||
其中，`gpus` 控制使用的显卡的ID，例如 "0,1";
|
||||
|
||||
`num_gpus` 控制使用的卡数;
|
||||
|
||||
`max_gpu_memory` 控制每个卡使用的显存容量。
|
||||
|
||||
注1：server_config.py的FSCHAT_MODEL_WORKERS字典中也增加了相关配置，如有需要也可通过修改FSCHAT_MODEL_WORKERS字典中对应参数实现多卡加载。
|
||||
|
||||
注2：少数情况下，gpus参数会不生效，此时需要通过设置环境变量CUDA_VISIBLE_DEVICES来指定torch可见的gpu,示例代码：
|
||||
|
||||
```shell
|
||||
CUDA_VISIBLE_DEVICES=0,1 python startup.py -a
|
||||
```
|
||||
|
||||
#### 5.4 PEFT 加载(包括lora,p-tuning,prefix tuning, prompt tuning,ia3等)
|
||||
|
||||
本项目基于 FastChat 加载 LLM 服务，故需以 FastChat 加载 PEFT 路径，即保证路径名称里必须有 peft 这个词，配置文件的名字为 adapter_config.json，peft 路径下包含.bin 格式的 PEFT 权重，peft路径在startup.py中create_model_worker_app函数的args.model_names中指定，并开启环境变量PEFT_SHARE_BASE_WEIGHTS=true参数。
|
||||
|
||||
注：如果上述方式启动失败，则需要以标准的fastchat服务启动方式分步启动，分步启动步骤参考第六节，PEFT加载详细步骤参考[加载lora微调后模型失效](https://github.com/chatchat-space/Langchain-Chatchat/issues/1130#issuecomment-1685291822)，
|
||||
|
||||
#### **5.5 注意事项：**
|
||||
|
||||
**1. startup 脚本用多进程方式启动各模块的服务，可能会导致打印顺序问题，请等待全部服务发起后再调用，并根据默认或指定端口调用服务（默认 LLM API 服务端口：`127.0.0.1:8888`,默认 API 服务端口：`127.0.0.1:7861`,默认 WebUI 服务端口：`本机IP：8501`)**
|
||||
|
||||
**2.服务启动时间示设备不同而不同，约 3-10 分钟，如长时间没有启动请前往 `./logs`目录下监控日志，定位问题。**
|
||||
|
||||
**3. 在Linux上使用ctrl+C退出可能会由于linux的多进程机制导致multiprocessing遗留孤儿进程，可通过shutdown_all.sh进行退出**
|
||||
|
||||
#### 5.6 启动界面示例：
|
||||
|
||||
1. FastAPI docs 界面
|
||||
|
||||
|
||||
|
||||
2. webui启动界面示例：
|
||||
|
||||

|
||||
|
||||
- Web UI 知识库管理页面：
|
||||
|
||||
|
||||
### 6 分步启动 API 服务或 Web UI
|
||||
|
||||
注意：如使用了一键启动方式，可忽略本节。
|
||||
|
||||
#### 6.1 启动 LLM 服务
|
||||
|
||||
如需使用开源模型进行本地部署，需首先启动 LLM 服务，启动方式分为三种：
|
||||
|
||||
- [基于多进程脚本 llm_api.py 启动 LLM 服务](README.md#5.1.1-基于多进程脚本-llm_api.py-启动-LLM-服务)
|
||||
- [基于命令行脚本 llm_api_stale.py 启动 LLM 服务](README.md#5.1.2-基于命令行脚本-llm_api_stale.py-启动-LLM-服务)
|
||||
- [PEFT 加载](README.md#5.1.3-PEFT-加载)
|
||||
|
||||
三种方式只需选择一个即可，具体操作方式详见 5.1.1 - 5.1.3。
|
||||
|
||||
如果启动在线的API服务（如 OPENAI 的 API 接口），则无需启动 LLM 服务，即 5.1 小节的任何命令均无需启动。
|
||||
|
||||
##### 6.1.1 基于多进程脚本 llm_api.py 启动 LLM 服务
|
||||
|
||||
在项目根目录下，执行 [server/llm_api.py](server/llm_api.py) 脚本启动 **LLM 模型**服务：
|
||||
|
||||
```shell
|
||||
$ python server/llm_api.py
|
||||
```
|
||||
|
||||
项目支持多卡加载，需在 llm_api.py 中的 create_model_worker_app 函数中，修改如下三个参数:
|
||||
|
||||
```python
|
||||
gpus=None,
|
||||
num_gpus=1,
|
||||
max_gpu_memory="20GiB"
|
||||
```
|
||||
|
||||
其中，`gpus` 控制使用的显卡的ID，如果 "0,1";
|
||||
|
||||
`num_gpus` 控制使用的卡数;
|
||||
|
||||
`max_gpu_memory` 控制每个卡使用的显存容量。
|
||||
|
||||
##### 6.1.2 基于命令行脚本 llm_api_stale.py 启动 LLM 服务
|
||||
|
||||
⚠️ **注意:**
|
||||
|
||||
**1.llm_api_stale.py脚本原生仅适用于linux,mac设备需要安装对应的linux命令,win平台请使用wsl;**
|
||||
|
||||
**2.加载非默认模型需要用命令行参数--model-path-address指定模型，不会读取model_config.py配置;**
|
||||
|
||||
在项目根目录下，执行 [server/llm_api_stale.py](server/llm_api_stale.py) 脚本启动 **LLM 模型**服务：
|
||||
|
||||
```shell
|
||||
$ python server/llm_api_stale.py
|
||||
```
|
||||
|
||||
该方式支持启动多个worker，示例启动方式：
|
||||
|
||||
```shell
|
||||
$ python server/llm_api_stale.py --model-path-address model1@host1@port1 model2@host2@port2
|
||||
```
|
||||
|
||||
如果出现server端口占用情况，需手动指定server端口,并同步修改model_config.py下对应模型的base_api_url为指定端口:
|
||||
|
||||
```shell
|
||||
$ python server/llm_api_stale.py --server-port 8887
|
||||
```
|
||||
|
||||
如果要启动多卡加载，示例命令如下：
|
||||
|
||||
```shell
|
||||
$ python server/llm_api_stale.py --gpus 0,1 --num-gpus 2 --max-gpu-memory 10GiB
|
||||
```
|
||||
|
||||
注：以如上方式启动LLM服务会以nohup命令在后台运行 FastChat 服务，如需停止服务，可以运行如下命令：
|
||||
|
||||
```shell
|
||||
$ python server/llm_api_shutdown.py --serve all
|
||||
```
|
||||
|
||||
亦可单独停止一个 FastChat 服务模块，可选 [`all`, `controller`, `model_worker`, `openai_api_server`]
|
||||
|
||||
##### 6.1.3 PEFT 加载(包括lora,p-tuning,prefix tuning, prompt tuning,ia3等)
|
||||
|
||||
本项目基于 FastChat 加载 LLM 服务，故需以 FastChat 加载 PEFT 路径，即保证路径名称里必须有 peft 这个词，配置文件的名字为 adapter_config.json，peft 路径下包含 model.bin 格式的 PEFT 权重。
|
||||
详细步骤参考[加载lora微调后模型失效](https://github.com/chatchat-space/Langchain-Chatchat/issues/1130#issuecomment-1685291822)
|
||||
|
||||
|
||||
|
||||
#### 6.2 启动 API 服务
|
||||
|
||||
本地部署情况下，按照 [5.1 节](README.md#5.1-启动-LLM-服务)**启动 LLM 服务后**，再执行 [server/api.py](server/api.py) 脚本启动 **API** 服务；
|
||||
|
||||
在线调用API服务的情况下，直接执执行 [server/api.py](server/api.py) 脚本启动 **API** 服务；
|
||||
|
||||
调用命令示例：
|
||||
|
||||
```shell
|
||||
$ python server/api.py
|
||||
```
|
||||
|
||||
启动 API 服务后，可访问 `localhost:7861` 或 `{API 所在服务器 IP}:7861` FastAPI 自动生成的 docs 进行接口查看与测试。
|
||||
|
||||
- FastAPI docs 界面
|
||||
|
||||
|
||||
|
||||
#### 6.3 启动 Web UI 服务
|
||||
|
||||
按照 [5.2 节](README.md#5.2-启动-API-服务)**启动 API 服务后**，执行 [webui.py](webui.py) 启动 **Web UI** 服务（默认使用端口 `8501`）
|
||||
|
||||
```shell
|
||||
$ streamlit run webui.py
|
||||
```
|
||||
|
||||
使用 Langchain-Chatchat 主题色启动 **Web UI** 服务（默认使用端口 `8501`）
|
||||
|
||||
```shell
|
||||
$ streamlit run webui.py --theme.base "light" --theme.primaryColor "#165dff" --theme.secondaryBackgroundColor "#f5f5f5" --theme.textColor "#000000"
|
||||
```
|
||||
|
||||
或使用以下命令指定启动 **Web UI** 服务并指定端口号
|
||||
|
||||
```shell
|
||||
$ streamlit run webui.py --server.port 666
|
||||
```
|
||||
|
||||
- Web UI 对话界面：

## Introduction
|
||||
|
||||
🤖️ A Q&A application based on local knowledge base implemented using the idea
|
||||
of [langchain](https://github.com/langchain-ai/langchain). The goal is to build a KBQA(Knowledge based Q&A) solution
|
||||
that
|
||||
is friendly to Chinese scenarios and open source models and can run both offline and online.
|
||||
|
||||
💡 Inspired by [document.ai](https://github.com/GanymedeNil/document.ai)
|
||||
and [ChatGLM-6B Pull Request](https://github.com/THUDM/ChatGLM-6B/pull/216) , we build a local knowledge base question

answering application that can be implemented using an open source model or remote LLM api throughout the process. In
|
||||
the latest version of this project, [FastChat](https://github.com/lm-sys/FastChat) is used to access Vicuna, Alpaca,
|
||||
LLaMA, Koala, RWKV and many other models. Relying on [langchain](https://github.com/langchain-ai/langchain) , this
|
||||
project supports calling services through the API provided based on [FastAPI](https://github.com/tiangolo/fastapi), or
|
||||
using the WebUI based on [Streamlit](https://github.com/streamlit/streamlit).
|
||||
|
||||
✅ Relying on the open source LLM and Embedding models, this project can realize full-process **offline private
|
||||
deployment**. At the same time, this project also supports the call of OpenAI GPT API- and Zhipu API, and will continue
|
||||
to expand the access to various models and remote APIs in the future.
|
||||
|
||||
⛓️ The implementation principle of this project is shown in the graph below. The main process includes: loading files ->
|
||||
reading text -> text segmentation -> text vectorization -> question vectorization -> matching the `top-k` most similar
|
||||
to the question vector in the text vector -> The matched text is added to `prompt `as context and question -> submitte
|
||||
to `LLM` to generate an answer.

|
||||
|
||||
Q6: 本项目中所需模型如何下载至本地？
|
||||
|
||||
A6: 本项目中使用的模型均为 `huggingface.com`中可下载的开源模型，以默认选择的 `chatglm-6b`和 `text2vec-large-chinese`模型为例，下载模型可执行如下代码：
|
||||
|
||||
```shell
|
||||
# 安装 git lfs
|
||||
$ git lfs install
|
||||
|
||||
# 下载 LLM 模型
|
||||
$ git clone https://huggingface.co/THUDM/chatglm-6b /your_path/chatglm-6b
|
||||
|
||||
# 下载 Embedding 模型
|
||||
$ git clone https://huggingface.co/GanymedeNil/text2vec-large-chinese /your_path/text2vec
|
||||
|
||||
# 模型需要更新时，可打开模型所在文件夹后拉取最新模型文件/代码
|
||||
$ git pull
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
Q7: `huggingface.com`中模型下载速度较慢怎么办？
|
||||
|
||||
A7: 可使用本项目用到的模型权重文件百度网盘地址：

|
||||
|
||||
Q8: 下载完模型后，如何修改代码以执行本地模型？
|
||||
|
||||
A8: 模型下载完成后，请在 [configs/model_config.py](../configs/model_config.py) 文件中，对 `embedding_model_dict`和 `llm_model_dict`参数进行修改，如把 `llm_model_dict`从
|
||||
|
||||
```python
|
||||
embedding_model_dict = {
|
||||
"ernie-tiny": "nghuyong/ernie-3.0-nano-zh",
|
||||
"ernie-base": "nghuyong/ernie-3.0-base-zh",
|
||||
"text2vec": "GanymedeNil/text2vec-large-chinese"
|
||||
}
|
||||
```
|
||||
|
||||
修改为
|
||||
|
||||
```python
|
||||
embedding_model_dict = {
|
||||
"ernie-tiny": "nghuyong/ernie-3.0-nano-zh",
|
||||
"ernie-base": "nghuyong/ernie-3.0-base-zh",
|
||||
"text2vec": "/Users/liuqian/Downloads/ChatGLM-6B/text2vec-large-chinese"
|
||||
}
|
||||
```
|
||||

||||
---
|
||||
|
||||
Q9: 执行 `python cli_demo.py`过程中，显卡内存爆了，提示 "OutOfMemoryError: CUDA out of memory"
|
||||
|
||||
A9: 将 `VECTOR_SEARCH_TOP_K` 和 `LLM_HISTORY_LEN` 的值调低，比如 `VECTOR_SEARCH_TOP_K = 5` 和 `LLM_HISTORY_LEN = 2`，这样由 `query` 和 `context` 拼接得到的 `prompt` 会变短，会减少内存的占用。或者打开量化，请在 [configs/model_config.py](../configs/model_config.py) 文件中，对`LOAD_IN_8BIT`参数进行修改
|
||||

|
||||
|
||||
Q10: 执行 `pip install -r requirements.txt` 过程中遇到 python 包，如 langchain 找不到对应版本的问题
|
||||
|
||||
A10: 更换 pypi 源后重新安装，如阿里源、清华源等，网络条件允许时建议直接使用 pypi.org 源，具体操作命令如下：
|
||||
|
||||
```shell
|
||||
# 使用 pypi 源
|
||||
$ pip install -r requirements.txt -i https://pypi.python.org/simple
|
||||
```
|
||||
|
||||
或
|
||||
|
||||
```shell
|
||||
# 使用阿里源
|
||||
$ pip install -r requirements.txt -i http://mirrors.aliyun.com/pypi/simple/
|
||||
```
|
||||
|
||||
或
|
||||
|
||||
```shell
|
||||
# 使用清华源
|
||||
$ pip install -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple/
|
||||
```

|
||||
Q11: 启动 api.py 时 upload_file 接口抛出 `partially initialized module 'charset_normalizer' has no attribute 'md__mypyc' (most likely due to a circular import)`
|
||||
|
||||
A11: 这是由于 charset_normalizer 模块版本过高导致的，需要降低低 charset_normalizer 的版本,测试在 charset_normalizer==2.1.0 上可用。
|
||||
|
||||
---
|
||||
|
||||
Q12: 调用api中的 `bing_search_chat` 接口时，报出 `Failed to establish a new connection: [Errno 110] Connection timed out`
|
||||
|
||||
A12: 这是因为服务器加了防火墙，需要联系管理员加白名单，如果公司的服务器的话，就别想了GG--!
|
||||
|
||||

|
||||
|
||||
Q13: 加载 chatglm-6b-int8 或 chatglm-6b-int4 抛出 `RuntimeError: Only Tensors of floating point andcomplex dtype can require gradients`
|
||||
|
||||
A13: 疑为 chatglm 的 quantization 的问题或 torch 版本差异问题，针对已经变为 Parameter 的 torch.zeros 矩阵也执行 Parameter 操作，从而抛出 `RuntimeError: Only Tensors of floating point andcomplex dtype can require gradients`。解决办法是在 chatglm 项目的原始文件中的 quantization.py 文件 374 行改为：
|
||||
|
||||
```
|
||||
try:
|
||||
self.weight =Parameter(self.weight.to(kwargs["device"]), requires_grad=False)
|
||||
except Exception as e:
|
||||
pass
|
||||
```
|
||||
|
||||
如果上述方式不起作用，则在.cache/hugggingface/modules/目录下针对chatglm项目的原始文件中的quantization.py文件执行上述操作，若软链接不止一个，按照错误提示选择正确的路径。
|
||||
|
||||
注：虽然模型可以顺利加载但在cpu上仍存在推理失败的可能：即针对每个问题，模型一直输出gugugugu。
|
||||
|
||||
因此，最好不要试图用cpu加载量化模型，原因可能是目前python主流量化包的量化操作是在gpu上执行的,会天然地存在gap。
|

|
||||
|
||||
Q14: 修改配置中路径后，加载 text2vec-large-chinese 依然提示 `WARNING: No sentence-transformers model found with name text2vec-large-chinese. Creating a new one with MEAN pooling.`
|
||||
|
||||
A14: 尝试更换 embedding，如 text2vec-base-chinese，请在 [configs/model_config.py](../configs/model_config.py) 文件中，修改 `text2vec-base`参数为本地路径，绝对路径或者相对路径均可

Q15: 使用pg向量库建表报错
|
||||
|
||||
A15: 需要手动安装对应的vector扩展(连接pg执行 CREATE EXTENSION IF NOT EXISTS vector)

|
||||

||||
Q16: pymilvus 连接超时
|
||||
|
||||
A16.pymilvus版本需要匹配和milvus对应否则会超时参考pymilvus==2.1.3

$ git clone https://github.com/chatchat-space/Langchain-Chatchat.git
|
||||
|
||||
# 进入目录
|
||||
$ cd Langchain-Chatchat
|
||||
|
||||
# 安装全部依赖
|
||||
$ pip install -r requirements.txt
|
||||
|
||||
# 默认依赖包括基本运行环境（FAISS向量库）。如果要使用 milvus/pg_vector 等向量库，请将 requirements.txt 中相应依赖取消注释再安装。
|
||||
```
|
||||
|
||||
此外，为方便用户 API 与 webui 分离运行，可单独根据运行需求安装依赖包。
|
||||
|
||||
- 如果只需运行 API，可执行：
|
||||
```shell
|
||||
$ pip install -r requirements_api.txt
|
||||
|
||||
# 默认依赖包括基本运行环境（FAISS向量库）。如果要使用 milvus/pg_vector 等向量库，请将 requirements.txt 中相应依赖取消注释再安装。
|
||||
```
|
||||
|
||||
- 如果只需运行 WebUI，可执行：
|
||||
```shell
|
||||
$ pip install -r requirements_webui.txt
|
||||
```
|
||||
|
||||
|
||||
|
||||
注：使用 `langchain.document_loaders.UnstructuredFileLoader` 进行 `.docx` 等格式非结构化文件接入时，可能需要依据文档进行其他依赖包的安装，请参考 [langchain 文档](https://python.langchain.com/en/latest/modules/indexes/document_loaders/examples/unstructured_file.html)。

## Issue with Installing Packages Using pip in Anaconda
|
||||
|
||||
## Problem
|
||||
|
||||
Recently, when running open-source code, I encountered an issue: after creating a virtual environment with conda and switching to the new environment, using pip to install packages would be "ineffective." Here, "ineffective" means that the packages installed with pip are not in this new environment.
|
||||
|
||||
------
|
||||
|
||||
## Analysis
|
||||
|
||||
1. First, create a test environment called test: `conda create -n test`
|
||||
2. Activate the test environment: `conda activate test`
|
||||
3. Use pip to install numpy: `pip install numpy`. You'll find that numpy already exists in the default environment.
|
||||
|
||||
```powershell
|
||||
Looking in indexes: https://pypi.tuna.tsinghua.edu.cn/simple
|
||||
Requirement already satisfied: numpy in c:\programdata\anaconda3\lib\site-packages (1.20.3)
|
||||
```
|
||||
|
||||
4. Check the information of pip: `pip show pip`
|
||||
|
||||
```powershell
|
||||
Name: pip
|
||||
Version: 21.2.4
|
||||

||||
Required-by:
|
||||
```
|
||||
|
||||
5. We can see that the current pip is in the default conda environment. This explains why the package is not in the new virtual environment when we directly use pip to install packages - because the pip being used belongs to the default environment, the installed package either already exists or is installed directly into the default environment.
|
||||
|
||||
------
|
||||
|
||||
## Solution
|
||||
|
||||
1. We can directly use the conda command to install new packages, but sometimes conda may not have certain packages/libraries, so we still need to use pip to install.
|
||||
2. We can first use the conda command to install the pip package for the current virtual environment, and then use pip to install new packages.
|
||||
|
||||
```powershell
|
||||
# Use conda to install the pip package
|
||||

||||
wincertstore 0.2
|
||||
```
|
||||
|
||||
## Supplement
|
||||
|
||||
1. The reason I didn't notice this problem before might be because the packages installed in the virtual environment were of a specific version, which overwrote the packages in the default environment. The main issue was actually a lack of careful observation:), otherwise, I could have noticed `Successfully uninstalled numpy-xxx` **default version** and `Successfully installed numpy-1.20.3` **specified version**.
|
||||
2. During testing, I found that if the Python version is specified when creating a new package, there shouldn't be this issue. I guess this is because pip will be installed in the virtual environment, while in our case, including pip, no packages were installed, so the default environment's pip was used.
|
||||
3. There's a question: I should have specified the Python version when creating a new virtual environment before, but I still used the default environment's pip package. However, I just couldn't reproduce the issue successfully on two different machines, which led to the second point mentioned above.
|
||||
4. After encountering the problem mentioned in point 3, I solved it by using `python -m pip install package-name`, adding `python -m` before pip. As for why, you can refer to the answer on [StackOverflow](https://stackoverflow.com/questions/41060382/using-pip-to-install-packages-to-anaconda-environment):
|
||||
|
||||
>1. If you have a non-conda pip as your default pip but conda python as your default python (as below):
|
||||
>
|
||||
>```shell
|
||||
>>which -a pip
|
||||
>/home/<user>/.local/bin/pip
|
||||
>/home/<user>/.conda/envs/newenv/bin/pip
|
||||
>/usr/bin/pip
|
||||
>
|
||||
>>which -a python
|
||||
>/home/<user>/.conda/envs/newenv/bin/python
|
||||
>/usr/bin/python
|
||||
>```
|
||||
>
|
||||
>2. Then, instead of calling `pip install <package>` directly, you can use the module flag -m in python so that it installs with the anaconda python
|
||||
>
|
||||
>```shell
|
||||
>python -m pip install <package>
|
||||
>```
|
||||
>
|
||||
>3. This will install the package to the anaconda library directory rather than the library directory associated with the (non-anaconda) pip
|
||||
>4. The reason for doing this is as follows: the pip command references a specific pip file/shortcut (which -a pip will tell you which one). Similarly, the python command references a specific python file (which -a python will tell you which one). For one reason or another, these two commands can become out of sync, so your "default" pip is in a different folder than your default python and therefore is associated with different versions of python.
|
||||
>5. In contrast, the python -m pip construct does not use the shortcut that the pip command points to. Instead, it asks python to find its pip version and use that version to install a package.

# 启动API服务
|
||||
|
||||
## 通过py文件启动
|
||||
可以通过直接执行`api.py`文件启动API服务，默认以ip:0.0.0.0和port:7861启动http和ws服务。
|
||||
```shell
|
||||
python api.py
|
||||
```
|
||||
同时，启动时支持StartOption所列的模型加载参数，同时还支持IP和端口设置。
|
||||
```shell
|
||||
python api.py --model-name chatglm-6b-int8 --port 7862
|
||||
```
|
||||
|
||||
## 通过cli.bat/cli.sh启动
|
||||
也可以通过命令行控制文件继续启动。
|
||||
```shell
|
||||
cli.sh api --help
|
||||
```
|
||||
其他可设置参数和上述py文件启动方式相同。
|
||||
|
||||
|
||||
# 以https、wss启动API服务
|
||||
## 本地创建ssl相关证书文件
|
||||
如果没有正式签发的CA证书，可以[安装mkcert](https://github.com/FiloSottile/mkcert#installation)工具， 然后用如下指令生成本地CA证书：
|
||||
```shell
|
||||
mkcert -install
|
||||
mkcert api.example.com 47.123.123.123 localhost 127.0.0.1 ::1
|
||||
```
|
||||
默认回车保存在当前目录下，会有以生成指令第一个域名命名为前缀命名的两个pem文件。
|
||||
|
||||
附带两个文件参数启动即可。
|
||||
````shell
|
||||
python api --port 7862 --ssl_keyfile api.example.com+4-key.pem --ssl_certfile api.example.com+4.pem
|
||||
|
||||
./cli.sh api --port 7862 --ssl_keyfile api.example.com+4-key.pem --ssl_certfile api.example.com+4.pem
|
||||
````
|
||||
|
||||
此外可以通过前置Nginx转发实现类似效果，可另行查阅相关资料。

## 在 Anaconda 中使用 pip 安装包无效问题
|
||||
|
||||
## 问题
|
||||
|
||||
最近在跑开源代码的时候遇到的问题：使用 conda 创建虚拟环境并切换到新的虚拟环境后，再使用 pip 来安装包会“无效”。这里的“无效”指的是使用 pip 安装的包不在这个新的环境中。
|
||||
|
||||
------
|
||||
|
||||
## 分析
|
||||
|
||||
1、首先创建一个测试环境 test，`conda create -n test`
|
||||
|
||||
2、激活该测试环境，`conda activate test`
|
||||
|
||||
3、使用 pip 安装 numpy，`pip install numpy`，会发现 numpy 已经存在默认的环境中
|
||||
|
||||
```powershell
|
||||
Looking in indexes: https://pypi.tuna.tsinghua.edu.cn/simple
|
||||
Requirement already satisfied: numpy in c:\programdata\anaconda3\lib\site-packages (1.20.3)
|
||||
```
|
||||
|
||||
4、这时候看一下 pip 的信息，`pip show pip`
|
||||
|
||||
```powershell
|
||||
Name: pip
|
||||
Version: 21.2.4

||||

||||

|
||||
```
|
||||
|
||||
5、可以发现当前 pip 是在默认的 conda 环境中。这也就解释了当我们直接使用 pip 安装包时为什么包不在这个新的虚拟环境中，因为使用的 pip 属于默认环境，安装的包要么已经存在，要么直接装到默认环境中去了。
|
||||
|
||||
------
|
||||
|
||||
## 解决
|
||||
|
||||
1、我们可以直接使用 conda 命令安装新的包，但有些时候 conda 可能没有某些包/库，所以还是得用 pip 安装
|
||||
|
||||
2、我们可以先使用 conda 命令为当前虚拟环境安装 pip 包，再使用 pip 安装新的包
|
||||
|
||||
```powershell
|
||||
# 使用 conda 安装 pip 包

||||

|
||||
|
||||
## 补充
|
||||
|
||||
1、之前没有发现这个问题可能时因为在虚拟环境中安装的包是指定版本的，覆盖了默认环境中的包。其实主要还是观察不仔细：），不然可以发现 `Successfully uninstalled numpy-xxx`【默认版本】 以及 `Successfully installed numpy-1.20.3`【指定版本】
|
||||
|
||||
2、测试时发现如果在新建包的时候指定了 python 版本的话应该是没有这个问题的，猜测时因为会在虚拟环境中安装好 pip ，而我们这里包括 pip 在内啥包也没有装，所以使用的是默认环境的 pip
|
||||
|
||||
3、有个问题，之前我在创建新的虚拟环境时应该指定了 python 版本，但还是使用的默认环境的 pip 包，但是刚在在两台机器上都没有复现成功，于是有了上面的第 2 点
|
||||
|
||||
4、出现了第 3 点的问题后，我当时是使用 `python -m pip install package-name` 解决的，在 pip 前面加上了 python -m。至于为什么，可以参考 [StackOverflow](https://stackoverflow.com/questions/41060382/using-pip-to-install-packages-to-anaconda-environment) 上的回答：
|
||||
|
||||

|
||||

|
||||

|
||||

|
||||
