## Docker 整合包
🐳 Docker镜像地址`registry.cn-beijing.aliyuncs.com/isafetech/chatmydata:1.0 `🌲
以上模型支持列表可能随 [FastChat](https://github.com/lm-sys/FastChat) 更新而持续更新,可参考 [FastChat 已支持模型列表](https://github.com/lm-sys/FastChat/blob/main/docs/model_support.md)。
💻 一行命令运行:
```shell
docker run -d -p 80:7860 --gpus all registry.cn-beijing.aliyuncs.com/isafetech/chatmydata:1.0
```
除本地模型外,本项目也支持直接接入 OpenAI API具体设置可参考 `configs/model_configs.py.example` 中的 `llm_model_dict``openai-chatgpt-3.5` 配置信息。
- 该版本镜像大小`25.2G`,使用[v0.1.16](https://github.com/imClumsyPanda/langchain-ChatGLM/releases/tag/v0.1.16),以`nvidia/cuda:12.1.1-cudnn8-runtime-ubuntu22.04`为基础镜像
- 该版本内置两个`embedding`模型:`m3e-base``text2vec-large-chinese`,内置`fastchat+chatglm-6b`
- 该版本目标为方便一键部署使用请确保您已经在Linux发行版上安装了NVIDIA驱动程序
- 请注意您不需要在主机系统上安装CUDA工具包但需要安装`NVIDIA Driver`以及`NVIDIA Container Toolkit`,请参考[安装指南](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/install-guide.html)
- 首次拉取和启动均需要一定时间,首次启动时请参照下图使用`docker logs -f <container id>`查看日志
- 如遇到启动过程卡在`Waiting..`步骤,建议使用`docker exec -it <container id> bash`进入`/logs/`目录查看对应阶段日志

## Docker 部署
为了能让容器使用主机GPU资源需要在主机上安装 [NVIDIA Container Toolkit](https://github.com/NVIDIA/nvidia-container-toolkit)。具体安装步骤如下:
```shell
sudo apt-get update
sudo apt-get install -y nvidia-container-toolkit-base
sudo systemctl daemon-reload
sudo systemctl restart docker
```
安装完成后,可以使用以下命令编译镜像和启动容器:
```
docker build -f Dockerfile-cuda -t chatglm-cuda:latest .
docker run --gpus all -d --name chatglm -p 7860:7860 chatglm-cuda:latest
#若要使用离线模型请配置好模型路径然后此repo挂载到Container
docker run --gpus all -d --name chatglm -p 7860:7860 -v ~/github/langchain-ChatGLM:/chatGLM chatglm-cuda:latest
```
AutoDL 镜像及 Docker 镜像制作中,将会在上传完成后增加。

vue前端需要node18环境
### 1. 开发环境准备
### 从本地加载模型
参见 [开发环境准备](docs/INSTALL.md)。
请参考 [THUDM/ChatGLM-6B#从本地加载模型](https://github.com/THUDM/ChatGLM-6B#从本地加载模型)
**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。
### 1. 安装环境
### 2. 下载模型至本地
参见 [安装指南](docs/INSTALL.md)
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
### 2. 设置模型默认参数
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:
在开始执行 Web UI 或命令行交互前,请先检查 [configs/model_config.py](configs/model_config.py) 中的各项模型参数设计是否符合需求。
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
如需通过 fastchat 以 api 形式调用 llm请参考 [fastchat 调用实现](docs/fastchat.md)
```Shell
$ git clone https://huggingface.co/THUDM/chatglm2-6b
### 3. 执行脚本体验 Web UI 或命令行交互
> 注:鉴于环境部署过程中可能遇到问题,建议首先测试命令行脚本。建议命令行脚本测试可正常运行后再运行 Web UI。
执行 [cli_demo.py](cli_demo.py) 脚本体验**命令行交互**
```shell
$ python cli_demo.py
$ git clone https://huggingface.co/moka-ai/m3e-base
```
或执行 [webui.py](webui.py) 脚本体验 **Web 交互**
### 3. 设置配置项
```shell
$ python webui.py
复制文件 [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`
在开始执行 Web UI 或命令行交互前,请先检查 `configs/model_config.py` 中的各项模型参数设计是否符合需求:
- 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"
},
}
```
或执行 [api.py](api.py) 利用 fastapi 部署 API
```shell
$ python api.py
```
或成功部署 API 后,执行以下脚本体验基于 VUE 的前端页面
```shell
$ cd views
- 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:
$ pnpm i
$ npm run dev
```python
embedding_model_dict = {
"m3e-base": "/Users/xxx/Downloads/m3e-base",
}
```
VUE 前端界面如下图所示:
1. `对话` 界面

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)。
Web UI 可以实现如下功能:
- 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 `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,需要以下命令初始化或重建知识库:
```shell
$ python init_database.py --recreate-vs
```
1. 运行前自动读取`configs/model_config.py``LLM``Embedding`模型枚举及默认模型设置运行模型,如需重新加载模型,可在 `模型配置` Tab 重新选择后点击 `重新加载模型` 进行模型加载;
2. 可手动调节保留对话历史长度、匹配知识库文段数量,可根据显存大小自行调节;
3. `对话` Tab 具备模式选择功能,可选择 `LLM对话``知识库问答` 模式进行对话,支持流式对话;
4. 添加 `配置知识库` 功能,支持选择已有知识库或新建知识库,并可向知识库中**新增**上传文件/文件夹,使用文件上传组件选择好文件后点击 `上传文件并加载知识库`,会将所选上传文档数据加载至知识库中,并基于更新后知识库进行问答;
5. 新增 `知识库测试 Beta` Tab可用于测试不同文本切分方法与检索相关度阈值设置暂不支持将测试参数作为 `对话` Tab 设置参数。
6. 后续版本中将会增加对知识库的修改或删除,及知识库中已导入文件的查看。
### 5. 启动 API 服务或 Web UI
#### 5.1 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
```
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

# ChatGLM Application with Local Knowledge Implementation
## Introduction
[![Telegram](https://img.shields.io/badge/Telegram-2CA5E0?style=for-the-badge&logo=telegram&logoColor=white "langchain-chatglm")](https://t.me/+RjliQ3jnJ1YyN2E9)
🌍 [_中文文档_](README.md)
🤖️ This is a ChatGLM application based on local knowledge, implemented using [ChatGLM-6B](https://github.com/THUDM/ChatGLM-6B) and [langchain](https://github.com/hwchase17/langchain).
💡 Inspired by [document.ai](https://github.com/GanymedeNil/document.ai) and [Alex Zhangji](https://github.com/AlexZhangji)'s [ChatGLM-6B Pull Request](https://github.com/THUDM/ChatGLM-6B/pull/216), this project establishes a local knowledge question-answering application using open-source models.
✅ The embeddings used in this project are [GanymedeNil/text2vec-large-chinese](https://huggingface.co/GanymedeNil/text2vec-large-chinese/tree/main), and the LLM is [ChatGLM-6B](https://github.com/THUDM/ChatGLM-6B). Relying on these models, this project enables the use of **open-source** models for **offline private deployment**.
⛓️ The implementation principle of this project is illustrated in the figure below. The process includes loading files -> reading text -> text segmentation -> text vectorization -> question vectorization -> matching the top k most similar text vectors to the question vector -> adding the matched text to `prompt` along with the question as context -> submitting to `LLM` to generate an answer.
![Implementation schematic diagram](img/langchain+chatglm.png)
🚩 This project does not involve fine-tuning or training; however, fine-tuning or training can be employed to optimize the effectiveness of this project.
📓 [ModelWhale online notebook](https://www.heywhale.com/mw/project/643977aa446c45f4592a1e59)
## Changelog
**[2023/04/15]**
1. refactor the project structure to keep the command line demo [cli_demo.py](cli_demo.py) and the Web UI demo [webui.py](webui.py) in the root directory.
2. Improve the Web UI by modifying it to first load the model according to the default option of [configs/model_config.py](configs/model_config.py) after running the Web UI, and adding error messages, etc.
3. Update FAQ.
**[2023/04/12]**
1. Replaced the sample files in the Web UI to avoid issues with unreadable files due to encoding problems in Ubuntu;
2. Replaced the prompt template in `knowledge_based_chatglm.py` to prevent confusion in the content returned by ChatGLM, which may arise from the prompt template containing Chinese and English bilingual text.
**[2023/04/11]**
1. Added Web UI V0.1 version (thanks to [@liangtongt](https://github.com/liangtongt));
2. Added Frequently Asked Questions in `README.md` (thanks to [@calcitem](https://github.com/calcitem) and [@bolongliu](https://github.com/bolongliu));
3. Enhanced automatic detection for the availability of `cuda`, `mps`, and `cpu` for LLM and Embedding model running devices;
4. Added a check for `filepath` in `knowledge_based_chatglm.py`. In addition to supporting single file import, it now supports a single folder path as input. After input, it will traverse each file in the folder and display a command-line message indicating the success of each file load.
5. **[2023/04/09]**
1. Replaced the previously selected `ChatVectorDBChain` with `RetrievalQA` in `langchain`, effectively reducing the issue of stopping due to insufficient video memory after asking 2-3 times;
2. Added `EMBEDDING_MODEL`, `VECTOR_SEARCH_TOP_K`, `LLM_MODEL`, `LLM_HISTORY_LEN`, `REPLY_WITH_SOURCE` parameter value settings in `knowledge_based_chatglm.py`;
3. Added `chatglm-6b-int4` and `chatglm-6b-int4-qe`, which require less GPU memory, as LLM model options;
4. Corrected code errors in `README.md` (thanks to [@calcitem](https://github.com/calcitem)).
**[2023/04/07]**
1. Resolved the issue of doubled video memory usage when loading the ChatGLM model (thanks to [@suc16](https://github.com/suc16) and [@myml](https://github.com/myml));
2. Added a mechanism to clear video memory;
3. Added `nghuyong/ernie-3.0-nano-zh` and `nghuyong/ernie-3.0-base-zh` as Embedding model options, which consume less video memory resources than `GanymedeNil/text2vec-large-chinese` (thanks to [@lastrei](https://github.com/lastrei)).

## 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.

## llama-cpp模型调用的说明
1. 首先从huggingface hub中下载对应的模型如 [https://huggingface.co/vicuna/ggml-vicuna-13b-1.1/](https://huggingface.co/vicuna/ggml-vicuna-13b-1.1/) 的 [ggml-vic13b-q5_1.bin](https://huggingface.co/vicuna/ggml-vicuna-13b-1.1/blob/main/ggml-vic13b-q5_1.bin)建议使用huggingface_hub库的snapshot_download下载。
2. 将下载的模型重命名。通过huggingface_hub下载的模型会被重命名为随机序列因此需要重命名为原始文件名如[ggml-vic13b-q5_1.bin](https://huggingface.co/vicuna/ggml-vicuna-13b-1.1/blob/main/ggml-vic13b-q5_1.bin)。
3. 基于下载模型的ggml的加载时间推测对应的llama-cpp版本下载对应的llama-cpp-python库的wheel文件实测[ggml-vic13b-q5_1.bin](https://huggingface.co/vicuna/ggml-vicuna-13b-1.1/blob/main/ggml-vic13b-q5_1.bin)与llama-cpp-python库兼容,然后手动安装wheel文件。
4. 将下载的模型信息写入configs/model_config.py文件里 `llm_model_dict`中,注意保证参数的兼容性,一些参数组合可能会报错.

# 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。增加 [clue-ai/ChatYuan](https://github.com/clue-ai/ChatYuan) 项目的模型 [ClueAI/ChatYuan-large-v2](https://huggingface.co/ClueAI/ChatYuan-large-v2) 的支持。
💡 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 默认选用的是 [GanymedeNil/text2vec-large-chinese](https://huggingface.co/GanymedeNil/text2vec-large-chinese/tree/main)LLM 默认选用的是 [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。
![实现原理图](img/langchain+chatglm.png)
从文档处理角度来看,实现流程如下:

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。
## Docker 部署
为了能让容器使用主机GPU资源需要在主机上安装 [NVIDIA Container Toolkit](https://github.com/NVIDIA/nvidia-container-toolkit)。具体安装步骤如下:
```shell
sudo apt-get update
sudo apt-get install -y nvidia-container-toolkit-base
sudo systemctl daemon-reload
sudo systemctl restart docker
```
安装完成后,可以使用以下命令编译镜像和启动容器:
```
docker build -f Dockerfile-cuda -t chatglm-cuda:latest .
docker run --gpus all -d --name chatglm -p 7860:7860 chatglm-cuda:latest
#若要使用离线模型请配置好模型路径然后此repo挂载到Container
docker run --gpus all -d --name chatglm -p 7860:7860 -v ~/github/langchain-ChatGLM:/chatGLM chatglm-cuda:latest
```
## 开发部署
### 软件需求
本项目已在 Python 3.8 - 3.10CUDA 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。
vue前端需要node18环境
### 从本地加载模型
请参考 [THUDM/ChatGLM-6B#从本地加载模型](https://github.com/THUDM/ChatGLM-6B#从本地加载模型)
### 1. 安装环境
参见 [安装指南](docs/INSTALL.md)。
### 2. 设置模型默认参数
在开始执行 Web UI 或命令行交互前,请先检查 [configs/model_config.py](configs/model_config.py) 中的各项模型参数设计是否符合需求。
### 3. 执行脚本体验 Web UI 或命令行交互
> 注:鉴于环境部署过程中可能遇到问题,建议首先测试命令行脚本。建议命令行脚本测试可正常运行后再运行 Web UI。
执行 [cli_demo.py](cli_demo.py) 脚本体验**命令行交互**
```shell
$ python cli_demo.py
```
或执行 [webui.py](webui.py) 脚本体验 **Web 交互**
```shell
$ python webui.py
```
或执行 [api.py](api.py) 利用 fastapi 部署 API
```shell
$ python api.py
```
或成功部署 API 后,执行以下脚本体验基于 VUE 的前端页面
```shell
$ cd views
$ pnpm i
$ npm run dev
```
执行后效果如下图所示:
1. `对话` Tab 界面
![](img/webui_0510_0.png)
2. `知识库测试 Beta` Tab 界面
![](img/webui_0510_1.png)
3. `模型配置` Tab 界面
![](img/webui_0510_2.png)
Web UI 可以实现如下功能:
1. 运行前自动读取`configs/model_config.py``LLM``Embedding`模型枚举及默认模型设置运行模型,如需重新加载模型,可在 `模型配置` Tab 重新选择后点击 `重新加载模型` 进行模型加载;
2. 可手动调节保留对话历史长度、匹配知识库文段数量,可根据显存大小自行调节;
3. `对话` Tab 具备模式选择功能,可选择 `LLM对话``知识库问答` 模式进行对话,支持流式对话;
4. 添加 `配置知识库` 功能,支持选择已有知识库或新建知识库,并可向知识库中**新增**上传文件/文件夹,使用文件上传组件选择好文件后点击 `上传文件并加载知识库`,会将所选上传文档数据加载至知识库中,并基于更新后知识库进行问答;
5. 新增 `知识库测试 Beta` Tab可用于测试不同文本切分方法与检索相关度阈值设置暂不支持将测试参数作为 `对话` Tab 设置参数。
6. 后续版本中将会增加对知识库的修改或删除,及知识库中已导入文件的查看。
### 常见问题
参见 [常见问题](docs/FAQ.md)。
## 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。
