复现操作

本来正常的，只是 git pull 到最新版，并且使用 pip install -r requirements.txt 更新了依赖，再启动就报错了。

运行环境

• OS: ubuntu
• Server:
• Gradio version:
• Python version: 3.10.6

补充说明

pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts. llama-index 0.5.25 requires langchain==0.0.142, but you have langchain 0.0.170 which is incompatible.

检查日志有这个问题，版本冲突，如果改0.0.142也不行~

请使用最新版代码。我删除了llama index这个依赖。

请使用最新版代码。我删除了llama index这个依赖。

我pull的就是最新版，你看看 modules/overwrites.py 这个文件中还有这个包呢，我试着把这个包注释了，可以启动，但会话又会报错。这个依赖没有处理干净。

[GaiZhenbiao]

现在应该没问题了，我新创建了一个虚拟环境测试没问题。
