# 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.
|
||||
|
||||
2. Please use `git pull --rebase` to fetch and merge updates from the upstream.
|
||||
|
||||
3. Rebase commits into well-formatted commits. Mention the issue being resolved in the commit message on a line all by itself like `Fixes #<bug>` (refer to [Linking a pull request to an issue](https://docs.github.com/en/issues/tracking-your-work-with-issues/linking-a-pull-request-to-an-issue) for more keywords you can use).
|
||||
|
||||
4. Push into `dev`. Mention which bug is being resolved in the description.

### 常见问题
|
||||
|
||||
## 快速上手
|
||||
参见 [常见问题](docs/FAQ.md)。
|
||||
|
||||
### 1. 环境配置
|
||||
## Demo
|
||||
|
||||
+ 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)。
|
||||
以问题`chatglm-6b 的局限性具体体现在哪里，如何实现改进`为例：
|
||||
|
||||
```
|
||||
$ python --version
|
||||
Python 3.11.7
|
||||
```
|
||||
未使用 langchain 接入本地文档时：
|
||||
|
||||
接着，创建一个虚拟环境，并在虚拟环境内安装项目的依赖
|
||||
>ChatGLM-6B 是一个基于 GPT-3 的聊天机器人,它的局限性主要体现在以下几个方面:
|
||||
>1. 语言模型的精度:GPT-3 是一种大型的语言模型,它的精度比较高,但是仍然有一些局限性。例如,它可能无法准确地理解某些方言、口音或者复杂的句子结构。
|
||||
>2. 知识图谱的完整性:GPT-3 可以生成一些知识图谱,但是其完整性和准确性可能不够。例如,它可能无法准确地理解某些领域的专业知识和术语。
|
||||
>3. 对话生成的连贯性:GPT-3 可以生成一些连贯的对话,但是其生成的对话可能不够自然。例如,它可能会生成一些虚假的、不连贯的对话或者误解用户的意图。
|
||||
>
|
||||
>为了改进 ChatGLM-6B,可以考虑以下几个方面:
|
||||
>1. 提高语言模型的精度:可以通过增加训练数据、使用更好的语言模型架构、优化模型训练过程等方式来提高语言模型的精度。
|
||||
>2. 增强知识图谱的完整性:可以通过增加知识图谱的维度、使用更好的知识图谱构建方法、优化知识图谱的匹配算法等方式来增强知识图谱的完整性。
|
||||
>3. 提高对话生成的连贯性:可以通过增加对话生成模型的上下文信息、使用更好的上下文信息提取方法、优化对话生成模型的算法等方式来提高对话生成的连贯性。
|
||||
>4. 引入更多的人类反馈:人类反馈可以帮助 ChatGLM-6B 更好地理解用户的意图和需求,从而提高对话生成的质量和准确性。可以通过引入更多的人类客服、使用人类反馈收集器等方式来引入更多的人类反馈。
|
||||
|
||||
```shell
|
||||
使用 langchain 接入 ChatGLM-6B 项目的 README.md 文件后 ChatGLM 的回答：
|
||||
>ChatGLM-6B 是一个基于深度学习的自然语言处理模型,它在回答问题方面表现出色。但是,它也有一些局限性,具体如下:
|
||||
>1. 语言理解有限:ChatGLM-6B 只学习了中文自然语言,对于其他语言可能会存在理解上的局限性。
|
||||
>2. 知识储备不足:ChatGLM-6B 的训练数据集只包含了中文语料,因此它可能无法回答一些非中文的问题或者某些特定领域的问题。
|
||||
>3. 数据量有限:ChatGLM-6B 的训练数据集只有几百万条记录,因此它可能无法回答一些非常具体或者复杂的问题。
|
||||
>
|
||||
>为了改进 ChatGLM-6B,可以考虑以下几个方面:
|
||||
>1. 学习更多的语言知识:可以学习其他语言的自然语言处理技术,扩大语言理解的范围。
|
||||
>2. 扩大知识储备:可以收集更多的中文语料,或者使用其他语言的数据集来扩充知识储备。
|
||||
>3. 增加数据量:可以使用更大的数据集来训练 ChatGLM-6B,提高模型的表现。
|
||||
>4. 引入更多的评估指标:可以引入更多的评估指标来评估模型的表现,从而发现 ChatGLM-6B 存在的不足和局限性。
|
||||
>5. 改进模型架构:可以改进 ChatGLM-6B 的模型架构,提高模型的性能和表现。例如,可以使用更大的神经网络或者改进的卷积神经网络结构。

# ChatGLM Application with Local Knowledge Implementation
|
||||
|
||||
## 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.

The main process analysis from the aspect of document process:
|
||||
|
||||
|
||||
|
||||
🚩 The training or fine-tuning are not involved in the project, but still, one always can improve performance by do
|
||||
these.
|
||||
|
||||
🌐 [AutoDL image](https://www.codewithgpu.com/i/chatchat-space/Langchain-Chatchat/Langchain-Chatchat) is supported, and in `0.2.10` the codes are update to v0.2.10.
|
||||
|
||||
🐳 [Docker image](isafetech/chatchat:0.2.10) is supported to ```0.2.10```.
|
||||
|
||||
🌲 The latest update also provides support for image sources from DockerHub, Ali Cloud, and Tencent Cloud:
|
||||
|
||||
```shell
|
||||
docker run -d --gpus all -p 80:8501 isafetech/chatchat:0.2.10
|
||||
docker run -d --gpus all -p 80:8501 uswccr.ccs.tencentyun.com/chatchat/chatchat:0.2.10
|
||||
docker run -d --gpus all -p 80:8501 registry.cn-beijing.aliyuncs.com/chatchat/chatchat:0.2.10
|
||||
```
|
||||
|
||||

## DEMO
|
||||
|
||||
Using the question "What are the limitations of ChatGLM-6B and how can they be improved?" as an example:
|
||||
|
||||
Without using langchain to access local documents:
|
||||
|
||||
> ChatGLM-6B is a chatbot based on GPT-3, and its limitations are mainly reflected in the following aspects:
|
||||
>
|
||||
> 1. Language model accuracy: Although GPT-3 is a large language model with relatively high accuracy, it still has some limitations. For instance, it may not be able to accurately understand certain dialects, accents, or complex sentence structures.
|
||||
> 2. Completeness of the knowledge graph: GPT-3 can generate some knowledge graphs, but its completeness and accuracy may not be sufficient. For example, it may struggle to accurately understand specific domain expertise and terminology.
|
||||
> 3. Coherence of dialogue generation: While GPT-3 can generate somewhat coherent dialogues, they may not always be natural. For instance, it may generate false, incoherent dialogue or misinterpret the user's intent.
|
||||
>
|
||||
> To improve ChatGLM-6B, consider the following aspects:
|
||||
>
|
||||
> 1. Enhance the accuracy of the language model: The accuracy of the language model can be improved by increasing the training data, using better language model architectures, and optimizing the model training process.
|
||||
> 2. Strengthen the integrity of the knowledge graph: The integrity of the knowledge graph can be enhanced by increasing its dimensions, employing better knowledge graph construction methods, and optimizing the knowledge graph's matching algorithm.
|
||||
> 3. Boost the coherence of dialogue generation: The coherence of dialogue generation can be improved by augmenting the context information of the dialogue generation model, utilizing better context information extraction methods, and optimizing the dialogue generation model's algorithm.
|
||||
> 4. Incorporate more human feedback: Human feedback can help ChatGLM-6B better understand users' intentions and needs, thereby improving the quality and accuracy of dialogue generation. More human feedback can be introduced by involving more human agents and using human feedback collectors.
|
||||
|
||||
ChatGLM's answer after using LangChain to access the README.md file of the ChatGLM-6B project:
|
||||
>ChatGLM-6B is a deep learning-based natural language processing model that excels at answering questions. However, it also has some limitations, as follows:
|
||||
>1. Limited language understanding: ChatGLM-6B has been primarily trained on Chinese natural language, and its understanding of other languages may be limited.
|
||||
>2. Insufficient knowledge base: The training dataset of ChatGLM-6B contains only a Chinese corpus, so it may not be able to answer non-Chinese questions or queries in specific domains.
|
||||
>3. Limited data volume: ChatGLM-6B's training dataset has only a few million records, which may hinder its ability to answer very specific or complex questions.
|
||||
>
|
||||
>To improve ChatGLM-6B, consider the following aspects:
|
||||
>1. Expand language knowledge: Learn natural language processing techniques in other languages to broaden the model's language understanding capabilities.
|
||||
>2. Broaden the knowledge base: Collect more Chinese corpora or use datasets in other languages to expand the model's knowledge base.
|
||||
>3. Increase data volume: Use larger datasets to train ChatGLM-6B, which can improve the model's performance.
|
||||
>4. Introduce more evaluation metrics: Incorporate additional evaluation metrics to assess the model's performance, which can help identify the shortcomings and limitations of ChatGLM-6B.
|
||||
>5. Enhance the model architecture: Improve ChatGLM-6B's model architecture to boost its performance and capabilities. For example, employ larger neural networks or refined convolutional neural network structures.

📃 **LangChain-Chatchat** (旧名 Langchain-ChatGLM)
|
||||
|
||||
ChatGLM などの大規模な言語モデルや Langchain などのアプリケーション フレームワークに基づいた、オープン
|
||||
ソースのオフライン展開可能な検索拡張生成 (RAG) 大規模モデル ナレッジ ベース プロジェクトです。
|
||||
|
||||
⚠️`0.2.10` は `0.2.x` シリーズの最終バージョンとなり、`0.2.x`
|
||||
シリーズはアップデートと技術サポートを終了し、より適用性の高い `Langchain-Chachat 0.3.x` の開発に努めます。 。

🤖️ [langchain](https://github.com/hwchase17/langchain) のアイデアを用いて実装された、ローカルナレッジベースに基づく Q&A
|
||||
アプリケーション。
|
||||
目標は、中国のシナリオとオープンソースモデルに親和性があり、オフラインとオンラインの両方で実行可能な KBQA（ナレッジベースの
|
||||
Q&A）ソリューションを構築することです。
|
||||
|
||||
💡 [document.ai](https://github.com/GanymedeNil/document.ai)
|
||||
と [ChatGLM-6B Pull Request](https://github.com/THUDM/ChatGLM-6B/pull/216) に触発され、
|
||||
プロセス全体を通してオープンソースモデルまたはリモート LLM api を使用して実装することができるローカルナレッジベースの質問応答アプリケーションを構築します。
|
||||
このプロジェクトの最新バージョンでは、[FastChat](https://github.com/lm-sys/FastChat)
|
||||
を使用して、Vicuna、Alpaca、LLaMA、Koala、RWKV、その他多くのモデルにアクセスしています。
|
||||
このプロジェクトは [langchain](https://github.com/langchain-ai/langchain)
|
||||
に依存し、[FastAPI](https://github.com/tiangolo/fastapi) に基づいて提供されるAPIを通してサービスを呼び出したり、
|
||||
[Streamlit](https://github.com/streamlit/streamlit) に基づいて WebUI を使ったりすることをサポートしています。
|
||||
|
||||
✅ オープンソースの LLM と Embedding モデルに依存して、このプロジェクトはフルプロセスの **オフラインプライベートデプロイメント
|
||||
** を実現することができます。
|
||||
同時に、本プロジェクトは OpenAI GPT API や Zhipu API の呼び出しにも対応しており、今後も様々な機種やリモート API
|
||||
へのアクセスを拡大していきます。
|
||||
|
||||
⛓️ このプロジェクトの実施原則を下のグラフに示します。主なプロセスは以下の通りです:
|
||||
ファイルの読み込み -> テキストの読み込み -> テキストのセグメンテーション -> テキストのベクトル化 -> 質問のベクトル化 ->
|
||||
質問ベクトルと最も似ている `top-k` をテキストベクトルでマッチング ->
|
||||
マッチしたテキストをコンテキストと質問として `prompt` に追加 -> 回答を生成するために `LLM` に送信。

|
||||
|
||||
🐳 [Docker イメージ](isafetech/chatchat:0.2.10)
|
||||
|
||||
🌲 今回のアップデートにより、DockerHub、阿里雲、騰訊のクラウドにも対応しました。より広範なクラウド環境で利用可能となりました。
|
||||
|
||||
```shell
|
||||
docker run -d --gpus all -p 80:8501 isafetech/chatchat:0.2.10
|
||||
docker run -d --gpus all -p 80:8501 uswccr.ccs.tencentyun.com/chatchat/chatchat:0.2.10
|
||||
docker run -d --gpus all -p 80:8501 registry.cn-beijing.aliyuncs.com/chatchat/chatchat:0.2.10
|

```
|
||||
|
||||
## ペインポイントへの対応
|
||||
|
||||
このプロジェクトは、完全にローカライズされた推論によってナレッジベースを強化するソリューションであり、特にデータセキュリティと企業向けのプライベートな展開の問題に取り組んでいます。
|
||||
このオープンソースソリューションは Apache ライセンスに基づき、無償で商用利用できます。
|
||||
私たちは、市場で入手可能な主流のローカル大予言モデルや Embedding モデル、オープンソースのローカルベクターデータベースをサポートしています。
|
||||
対応機種とデータベースの詳細については、[Wiki](https://github.com/chatchat-space/Langchain-Chatchat/wiki/) をご参照ください。
|
||||
|
||||
## クイックスタート
|
||||
|
||||
### 環境セットアップ
|
||||
|
||||
まず、マシンにPython 3.10がインストールされていることを確認してください。
|
||||
|
||||
```
|
||||
$ python --version
|
||||
Python 3.11.7
|
||||
```
|
||||
|
||||
次に、仮想環境を作成し、プロジェクトの依存関係を仮想環境内にインストールする。
|
||||
|
||||
```shell
|
||||
|
||||
# リポジトリをクローン
|
||||
$ git clone https://github.com/chatchat-space/Langchain-Chatchat.git
|
||||
|
||||
# ディレクトリに移動
|
||||
$ cd Langchain-Chatchat
|
||||
|
||||
# すべての依存関係をインストール

# 基于本地知识的 ChatGLM 应用实现
|
||||
|
||||
## 介绍
|
||||
|
||||
🌍 [_READ THIS IN ENGLISH_](README_en.md)
|
||||
|
||||
🤖️ 一种利用 [ChatGLM-6B](https://github.com/THUDM/ChatGLM-6B) + [langchain](https://github.com/hwchase17/langchain) 实现的基于本地知识的 ChatGLM 应用。
|
||||
|
||||
💡 受 [GanymedeNil](https://github.com/GanymedeNil) 的项目 [document.ai](https://github.com/GanymedeNil/document.ai) 和 [AlexZhangji](https://github.com/AlexZhangji) 创建的 [ChatGLM-6B Pull Request](https://github.com/THUDM/ChatGLM-6B/pull/216) 启发，建立了全部基于开源模型实现的本地知识问答应用。
|
||||
|
||||
✅ 本项目中 Embedding 选用的是 [GanymedeNil/text2vec-large-chinese](https://huggingface.co/GanymedeNil/text2vec-large-chinese/tree/main)，LLM 选用的是 [ChatGLM-6B](https://github.com/THUDM/ChatGLM-6B)。依托上述模型，本项目可实现全部使用**开源**模型**离线私有部署**。
|
||||
|
||||
⛓️ 本项目实现原理如下图所示，过程包括加载文件 -> 读取文本 -> 文本分割 -> 文本向量化 -> 问句向量化 -> 在文本向量中匹配出与问句向量最相似的`top k`个 -> 匹配出的文本作为上下文和问题一起添加到`prompt`中 -> 提交给`LLM`生成回答。
|
||||
|
||||
|
||||
|
||||
🚩 本项目未涉及微调、训练过程，但可利用微调或训练对本项目效果进行优化。
|
||||
|
||||
## 更新信息
|
||||
|
||||
**[2023/04/07]**
|
||||
1. 解决加载 ChatGLM 模型时发生显存占用为双倍的问题 (感谢 [@suc16](https://github.com/suc16) 和 [@myml](https://github.com/myml)) ；
|
||||
2. 新增清理显存机制；
|
||||
3. 新增`nghuyong/ernie-3.0-nano-zh`和`nghuyong/ernie-3.0-base-zh`作为 Embedding 模型备选项，相比`GanymedeNil/text2vec-large-chinese`占用显存资源更少 (感谢 [@lastrei](https://github.com/lastrei))。
|
||||
|
||||
**[2023/04/09]**
|
||||
1. 使用`langchain`中的`RetrievalQA`替代之前选用的`ChatVectorDBChain`，替换后可以有效减少提问 2-3 次后因显存不足而停止运行的问题；
|
||||
2. 在`knowledge_based_chatglm.py`中增加`EMBEDDING_MODEL`、`VECTOR_SEARCH_TOP_K`、`LLM_MODEL`、`LLM_HISTORY_LEN`、`REPLY_WITH_SOURCE`参数值设置；
|
||||
3. 增加 GPU 显存需求更小的`chatglm-6b-int4`、`chatglm-6b-int4-qe`作为 LLM 模型备选项；
|
||||
4. 更正`README.md`中的代码错误（感谢 [@calcitem](https://github.com/calcitem)）。
|
||||
|
||||
**[2023/04/11]**
|
||||
1. 加入 Web UI V0.1 版本（感谢 [@liangtongt](https://github.com/liangtongt)）；
|
||||
2. `README.md`中增加常见问题（感谢 [@calcitem](https://github.com/calcitem)）；
|
||||
3. 增加 LLM 和 Embedding 模型运行设备是否可用`cuda`、`mps`、`cpu`的自动判断。
|
||||
4. 在`knowledge_based_chatglm.py`中增加对`filepath`的判断，在之前支持单个文件导入的基础上，现支持单个文件夹路径作为输入，输入后将会遍历文件夹中各个文件，并在命令行中显示每个文件是否成功加载。
|
||||
|
||||
## 使用方式
|
||||
|
||||
### 硬件需求
|
||||
- ChatGLM-6B 模型硬件需求
|
||||
|
||||
| **量化等级** | **最低 GPU 显存**（推理） | **最低 GPU 显存**（高效参数微调） |
|
||||
| -------------- | ------------------------- | --------------------------------- |
|
||||
| FP16（无量化） | 13 GB | 14 GB |
|
||||
| INT8 | 8 GB | 9 GB |
|
||||
| INT4 | 6 GB | 7 GB |
|
||||
|
||||
- Embedding 模型硬件需求
|
||||
|
||||
本项目中默认选用的 Embedding 模型 [GanymedeNil/text2vec-large-chinese](https://huggingface.co/GanymedeNil/text2vec-large-chinese/tree/main) 约占用显存 3GB，也可修改为在 CPU 中运行。
|
||||
### 软件需求
|
||||
本项目已在 python 3.8 环境下完成测试。
|
||||
### 1. 安装 python 依赖包
|
||||
```commandline
|
||||
pip install -r requirements.txt
|
||||
```
|
||||
注：使用 langchain.document_loaders.UnstructuredFileLoader 进行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)
|
||||
|
||||
### 2. 执行脚本体验 Web UI 或命令行交互
|
||||
执行 [webui.py](webui.py) 脚本体验 **Web 交互** <img src="https://img.shields.io/badge/Version-0.1-brightgreen">
|
||||
```commandline
|
||||
python webui.py
|
||||
```
|
||||
执行后效果如下图所示：
|
||||
|
||||
Web UI 中提供的 API 接口如下图所示：
|
||||
|
||||
Web UI 可以实现如下功能：
|
||||
1. 自动读取`knowledge_based_chatglm.py`中`LLM`及`embedding`模型枚举，选择后点击`setting`进行模型加载，可随时切换模型进行测试
|
||||
2. 可手动调节保留对话历史长度，可根据显存大小自行调节
|
||||
3. 添加上传文件功能，通过下拉框选择已上传的文件，点击`loading`加载文件，过程中可随时更换加载的文件
|
||||
4. 底部添加`use via API`可对接到自己系统
|
||||
|
||||
或执行 [knowledge_based_chatglm.py](knowledge_based_chatglm.py) 脚本体验**命令行交互**
|
||||
```commandline
|
||||
python knowledge_based_chatglm.py
|
||||
```
|
||||
|
||||
|
||||
### 常见问题
|
||||
Q: 本项目支持哪些文件格式？
|
||||
|
||||
A: 目前已测试支持 txt、docx、md 格式文件，更多文件格式请参考 [langchain 文档](https://python.langchain.com/en/latest/modules/indexes/document_loaders/examples/unstructured_file.html)。目前已知文档中若含有特殊字符，可能存在文件无法加载的问题。
|
||||
|
||||
Q: 读取特定格式文件时遇到缺少`detectron2`时如何解决？
|
||||
|
||||
A: 因该包安装过程中遇到问题较多，且仅部分格式文件需要，所以未加入`requirements.txt`。可以通过一下命令安装
|
||||
|
||||
```commandline
|
||||
pip install "detectron2@git+https://github.com/facebookresearch/detectron2.git@v0.6#egg=detectron2"
|
||||
```
|
||||
|
||||
Q: `Resource punkt not found.` 如何解决？
|
||||
|
||||
A: https://github.com/nltk/nltk_data/raw/gh-pages/packages/tokenizers/punkt.zip 中的 `packages/tokenizers` 解压，放到 `Searched in:` 对应目录下。
|
||||
|
||||
Q: `Resource averaged_perceptron_tagger not found.` 如何解决？
|
||||
|
||||
A: 将 https://github.com/nltk/nltk_data/blob/gh-pages/packages/taggers/averaged_perceptron_tagger.zip 下载，解压放到 `Searched in:` 对应目录下。
|
||||
|
||||
Q: 本项目可否在 colab 中运行？
|
||||
|
||||
A: 可以尝试使用 chatglm-6b-int4 模型在 colab 中运行，需要注意的是，如需在 colab 中运行 Web UI，需将`webui.py`中`demo.queue(concurrency_count=3).launch(
|
||||
server_name='0.0.0.0', share=False, inbrowser=False)`中参数`share`设置为`True`。
|
||||
## DEMO
|
||||
|
||||
以问题`chatglm-6b 的局限性具体体现在哪里，如何实现改进`为例
|
||||
|
||||
未使用 langchain 接入本地文档时：
|
||||
|
||||
>ChatGLM-6B 是一个基于 GPT-3 的聊天机器人,它的局限性主要体现在以下几个方面:
|
||||
>1. 语言模型的精度:GPT-3 是一种大型的语言模型,它的精度比较高,但是仍然有一些局限性。例如,它可能无法准确地理解某些方言、口音或者复杂的句子结构。
|
||||
>2. 知识图谱的完整性:GPT-3 可以生成一些知识图谱,但是其完整性和准确性可能不够。例如,它可能无法准确地理解某些领域的专业知识和术语。
|
||||
>3. 对话生成的连贯性:GPT-3 可以生成一些连贯的对话,但是其生成的对话可能不够自然。例如,它可能会生成一些虚假的、不连贯的对话或者误解用户的意图。
|
||||
>
|
||||
>为了改进 ChatGLM-6B,可以考虑以下几个方面:
|
||||
>1. 提高语言模型的精度:可以通过增加训练数据、使用更好的语言模型架构、优化模型训练过程等方式来提高语言模型的精度。
|
||||
>2. 增强知识图谱的完整性:可以通过增加知识图谱的维度、使用更好的知识图谱构建方法、优化知识图谱的匹配算法等方式来增强知识图谱的完整性。
|
||||
>3. 提高对话生成的连贯性:可以通过增加对话生成模型的上下文信息、使用更好的上下文信息提取方法、优化对话生成模型的算法等方式来提高对话生成的连贯性。
|
||||
>4. 引入更多的人类反馈:人类反馈可以帮助 ChatGLM-6B 更好地理解用户的意图和需求,从而提高对话生成的质量和准确性。可以通过引入更多的人类客服、使用人类反馈收集器等方式来引入更多的人类反馈。
|
||||
|
||||
使用 langchain 接入 ChatGLM-6B 项目的 README.md 文件后 ChatGLM 的回答：
|
||||
>ChatGLM-6B 是一个基于深度学习的自然语言处理模型,它在回答问题方面表现出色。但是,它也有一些局限性,具体如下:
|
||||
>1. 语言理解有限:ChatGLM-6B 只学习了中文自然语言,对于其他语言可能会存在理解上的局限性。
|
||||
>2. 知识储备不足:ChatGLM-6B 的训练数据集只包含了中文语料,因此它可能无法回答一些非中文的问题或者某些特定领域的问题。
|
||||
>3. 数据量有限:ChatGLM-6B 的训练数据集只有几百万条记录,因此它可能无法回答一些非常具体或者复杂的问题。
|
||||
>
|
||||
>为了改进 ChatGLM-6B,可以考虑以下几个方面:
|
||||
>1. 学习更多的语言知识:可以学习其他语言的自然语言处理技术,扩大语言理解的范围。
|
||||
>2. 扩大知识储备:可以收集更多的中文语料,或者使用其他语言的数据集来扩充知识储备。
|
||||
>3. 增加数据量:可以使用更大的数据集来训练 ChatGLM-6B,提高模型的表现。
|
||||
>4. 引入更多的评估指标:可以引入更多的评估指标来评估模型的表现,从而发现 ChatGLM-6B 存在的不足和局限性。
|
||||
>5. 改进模型架构:可以改进 ChatGLM-6B 的模型架构,提高模型的性能和表现。例如,可以使用更大的神经网络或者改进的卷积神经网络结构。

## 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

||||

||||
```
|
||||
|
||||
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
|
||||

||||

```
|
||||
|
||||
## 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.

## 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
|
||||

|
||||
Required-by:
|
||||
```
|
||||
|
||||
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
|
||||
(test) PS C:\Users\Administrator> conda install pip
|
||||
Collecting package metadata (current_repodata.json): done
|
||||
Solving environment: done
|
||||
....
|
||||
done
|
||||
|
||||
# 显示当前 pip 的信息，发现 pip 在测试环境 test 中
|

```
|
||||
|
||||
------
|
||||
|
||||
## 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：
|
||||
|
||||
> 1、如果你有一个非 conda 的 pip 作为你的默认 pip，但是 conda 的 python 是你的默认 python（如下）：
|
||||
>
|
||||
> ```shell
|
||||
> >which -a pip
|
||||
> /home/<user>/.local/bin/pip
|
||||

|

|

|
||||
> /usr/bin/python
|
||||
> ```
|
||||
>
|
||||
> 2、然后，而不是直接调用 `pip install <package>`，你可以在 python 中使用模块标志 -m，以便它使用 anaconda python 进行安装
|
||||
>
|
||||
> ```shell
|
||||
>python -m pip install <package>
|
||||
> ```
|
||||
>
|
||||
> 3、这将把包安装到 anaconda 库目录，而不是与（非anaconda） pip 关联的库目录
|
||||
>
|
||||
> 4、这样做的原因如下：命令 pip 引用了一个特定的 pip 文件 / 快捷方式（which -a pip 会告诉你是哪一个）。类似地，命令 python 引用一个特定的 python 文件（which -a python 会告诉你是哪个）。由于这样或那样的原因，这两个命令可能变得不同步，因此你的“默认” pip 与你的默认 python 位于不同的文件夹中，因此与不同版本的 python 相关联。
|
||||
>
|
||||
> 5、与此相反，python -m pip 构造不使用 pip 命令指向的快捷方式。相反，它要求 python 找到它的pip 版本，并使用该版本安装一个包。
