ImportError: cannot import name 'ServiceContext' from 'llama_index' (unknown location)

按照步骤安装完成，运行时报错： (history-rag) ubuntu@SKTech-Shanghai:/var/www/history_rag$ python cli.py --cfg cfgs/config_qwen.yaml Traceback (most recent call last): File "/var/www/history_rag/cli.py", line 1, in from executor import MilvusExecutor File "/var/www/history_rag/executor.py", line 12, in from llama_index import ServiceContext, StorageContext ImportError: cannot import name 'ServiceContext' from 'llama_index' (unknown location)

按照一些方法，llama_index已经更新到0.10.5版本了，仍然出现此问题，Python版本是3.10.12

你先试一下这个版本？llama-index 0.9.39,虽然 'llama_index' (unknown location)这个未知位置引起了我的注意。

感谢，问题已解决，看来真的是版本更迭的问题。

大神好，我在windows下遇到了同样的问题，请教如何回退版本，是否需要删除镜像重新编译，本人是小白，麻烦指教详细步骤，多谢！

今天也遇到了相同的问题，llama_index版本是0.10.6

我会升级到更高版本的llama_index
