How to properly import llama-index classes?
问题
最近，我在使用Llama Index进行一些PoC项目。我正在按照文档中的说明来使用不同索引的路由功能。我创建了两个索引，想要使用SubQueryEngine来路由我创建的查询引擎。
在教程中，我们有以下导入示例：
from llama_index import GPTVectorStoreIndex, SimpleDirectoryReader
from llama_index.tools import QueryEngineTool, ToolMetadata
from llama_index.query_engine import SubQuestionQueryEngine
但当我运行我的示例时，我无法导入ToolMetadata和SubQuestionQueryEngine。我遇到了以下错误：
ImportError: cannot import name 'SubQuestionQueryEngine' from 'llama_index.query_engine'
有谁知道可能出现的问题是什么？其他导入工作正常，我能够运行使用GPTVectorStoreIndex类的示例。
我正在使用Python 3.10.11
英文:
Recently I making some PoCs using Llama Index.
I'm following the documentation in order to use routing features for different indexes. I made two indexes and I want to use SubQueryEngine to route the query engines that I have created.
In the tutorial, we have the following example of imports:
from llama_index import GPTVectorStoreIndex, SimpleDirectoryReader
from llama_index.tools import QueryEngineTool, ToolMetadata
from llama_index.query_engine import SubQuestionQueryEngine
But when I run my example, I'm not able to import ToolMetadata neither SubQuestionQueryEngine. I got the following error:
ImportError: cannot import name 'SubQuestionQueryEngine' from 'llama_index.query_engine'
Does anybody know what possible can be the problem? The other imports work normaly and I was able to run examples using GPTVectorStoreIndex class.
I'm using Python 3.10.11

请提供您正在使用的llama-index版本。
一个简单的修复方法是：pip install -U llama-index。我经常遇到由于库的持续更新而引起的问题。我建议每天更新它，以确保您使用的是最新版本。
英文:
Please provide the version of llama-index that you are using.
A simple fix would be: pip install -U llama-index. I frequently encounter issues due to the continuous updates of the library. I would suggest updating it every day just to make sure you are using the latest version.
