问题描述 / Problem Description

在使用docker-compose启动时，chatchat容器发生错误：

sqlite3.OperationalError: unable to open database file

Xinference正常启动，并已运行qwen2-instruct与bge-m3。

复现问题的步骤 / Steps to Reproduce

按照下面的说明，执行到 5. 启动 chatchat & xinference 服务 时，chatchat示例发生以上错误。
https://github.com/chatchat-space/Langchain-Chatchat/blob/master/docs/install/README_docker.md

预期的结果 / Expected Result

不应该出现错误，chatchat服务应该正常启动。

实际结果 / Actual Result

chatchat服务发生错误，服务未能启动。

找到原因了，首次部署，还需要将data.tar.gz 文件(包含初始化后的数据库 samples 文件一份及相应目录结构)放置到对应挂载目录下并解压：

cd ~/chatchat
wget https://github.com/chatchat-space/Langchain-Chatchat/blob/master/docker/data.tar.gz
tar -xvf data.tar.gz

对应docker-compose配置：

(上文 ...)
chatchat:
volumes:
- ~/chatchat:/root/chatchat_data
(下文 ...)

首次部署的数据准备应该记录到[一. Langchain-Chatchat 体验部署]的步骤[5. 启动 chatchat & xinference 服务]之前。

建议修改一下文档：

$x_1^e_0^f_1^x$

确实挺无语，Docker中不配置此文件及自动解压，而且即便解压了也没有配置文件，还要：

进入容器 docker compose exec -it chatchat /bin/sh
然后在 /root/chatchat_data 目录下运行 chatchat init 才能生成配置文件

而且我用 0720 版本，没有生成 Langchain-Chatchat 相关文件夹，然后向量库一直用不了，改用最新的 0729 版本才正常了。

解决了，感谢。竟然还没改文档 😂
