Hello
Seeing the following exception when I execute the line index.as_query_engine(llm=None). What could be causing this issue?

File "/....../.venv/lib/python3.9/site-packages/llama_index/core/indices/base.py", line 391, in as_query_engine

probably that lock should have lazy initialization in the framework. Its a bug for now

GGayathri

Oh... Thank you @Logan M What do you suggest that I do? Roll back to an older version of llama-index? Or anything else?

LLogan M

You could roll back, or ensure your code/thread is running with an async loop initialized

GGayathri

How do I run the code in an async loop? Any pointers?
Or if I have to rollback, any other version in the 0.10.x series that you suggest?

GGayathri

The last version we had was 0.9.x where we were using Service Contaxt and this piece was working fine.

GGayathri

We would like to update to 0.10.x..

LLogan M

probably v0.10.15 or so? And not sure, seems like you are threading your code? Unfamiliar with that. This bug should also be fixed in future versions

GGayathri

Thank you @Logan M That is a good starter for me. Let me put my hands on this and see...

GGayathri

One question @Logan M Any rough idea around when this bug is exptected to be fixed?

LLogan M

its actually already merged into main, will be in the next release (probably tomorrow, if I have time)

GGayathri

That will be super helpful @Logan M, to see it in 0.10.28! Many thanks!

I already mentioned this. But just incase you have missed it. I am seeing similar errors when I simply import BaseEmbedding

Guess this PR - https://github.com/run-llama/llama_index/pull/12638 is the one that will fix the problem?

GGayathri

Thank you @Logan M for 0.10.28!! Helped us progress further!
