CONTRIBUTING.md

+# 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.

docs/CHANGELOG.md

+## 变更日志
+
+**[2023/04/15]**
+
+1. 重构项目结构，在根目录下保留命令行 Demo [cli_demo.py](../cli_demo.py) 和 Web UI Demo [webui.py](../webui.py)；
+2. 对 Web UI 进行改进，修改为运行 Web UI 后首先按照 [configs/model_config.py](../configs/model_config.py) 默认选项加载模型，并增加报错提示信息等；
+3. 对常见问题进行补充说明。
+
+**[2023/04/12]**
+
+1. 替换 Web UI 中的样例文件，避免出现 Ubuntu 中出现因文件编码无法读取的问题；
+2. 替换`knowledge_based_chatglm.py`中的 prompt 模版，避免出现因 prompt 模版包含中英双语导致 chatglm 返回内容错乱的问题。
+
+**[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) 和 [@bolongliu](https://github.com/bolongliu)）；
+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。
+
+**[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)）。
+
+**[2023/04/07]** 
+
+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))。

docs/FAQ.md

+### 常见问题
+
+Q1: 本项目支持哪些文件格式？
+
+A1: 目前已测试支持 txt、docx、md、pdf 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。
+
+---
+
+Q2: 执行 `pip install -r requirements.txt` 过程中，安装 `detectron2` 时发生报错怎么办？
+
+A2: 如果不需要对 `pdf` 格式文件读取，可不安装 `detectron2`；如需对 `pdf` 文件进行高精度文本提取，建议按照如下方法安装：
+
+```commandline
+$ git clone https://github.com/facebookresearch/detectron2.git
+$ cd detectron2
+$ pip install -e .
+```
+
+---
+
+Q3: 使用过程中 Python 包`nltk`发生了`Resource punkt not found.`报错，该如何解决？
+
+A3: https://github.com/nltk/nltk_data/raw/gh-pages/packages/tokenizers/punkt.zip 中的 `packages/tokenizers` 解压，放到  `nltk_data/tokenizers` 存储路径下。
+
+ `nltk_data` 存储路径可以通过 `nltk.data.path` 查询。
+
+---
+
+Q4: 使用过程中 Python 包`nltk`发生了`Resource averaged_perceptron_tagger not found.`报错，该如何解决？
+
+A4: 将 https://github.com/nltk/nltk_data/blob/gh-pages/packages/taggers/averaged_perceptron_tagger.zip 下载，解压放到 `nltk_data/taggers` 存储路径下。
+
+ `nltk_data` 存储路径可以通过 `nltk.data.path` 查询。
+
+---
+
+Q5: 本项目可否在 colab 中运行？
+
+A5: 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`。
+
+---
+
+Q6: 在 Anaconda 中使用 pip 安装包无效如何解决？
+
+A6: 此问题是系统环境问题，详细见  [在Anaconda中使用pip安装包无效问题](在Anaconda中使用pip安装包无效问题.md)
+
+---
+
+Q7: 本项目中所需模型如何下载至本地？
+
+A7: 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
+```
+
+---
+
+Q8: `huggingface.com`中模型下载速度较慢怎么办？
+
+A8: 可使用本项目用到的模型权重文件百度网盘地址：

+
+Q9: 下载完模型后，如何修改代码以执行本地模型？
+
+A9: 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
+
+```json
+embedding_model_dict = {

+# 安装
+
+## 环境检查
+
+```shell
+# 首先，确信你的机器安装了 Python 3.8 及以上版本
+$ python --version
+Python 3.8.13
+
+# 如果低于这个版本，可使用conda安装环境
+$ conda create -p /your_path/env_name python=3.8
+
+# 激活环境
+$ source activate /your_path/env_name
+
+# 关闭环境
+$ source deactivate /your_path/env_name
+
+# 删除环境
+$ conda env remove -p  /your_path/env_name
+```
+
+## 项目依赖
+
+```shell
+# 拉取仓库
+$ git clone https://github.com/imClumsyPanda/langchain-ChatGLM.git
+
+# 安装依赖
+$ pip install -r requirements.txt
+```
