Hi,
Thanks for the great article. I've a question here.

When executing dbqa(), it returned:
free(): invalid next size (normal)
Aborted (core dumped)

Any idea?

Here are the steps to reproduce to problem.

1. Modify the embedding model to "sentence-transformers/paraphrase-multilingual-mpnet-base-v2"
2. python db_build.py to build vectorestore
3. python main.py "MY QUERY STRING IS HERE"
