Expected behavior

Program does not crash but prints prompt and answer correctly.

There's also a different minor issue here with the final token (dot in the given example) being printed after llama timings dump, not sure it's worth reporting separately.

Thanks, i'll look at it later in time since it's not critical. On it rn here

Besides escaped { } the dot character should not cause any issues.

I had similar situation and I stopped the process since I thought that something went wrong and now every time I start my vscode.. it keeps killing my bash session..
Do I have to restart ingesting everything again? it will be great if there is a way to know if the machine is still working or stuck.. any suggestion/idea? Thanks in advance!

[su77ungr]

Ingesting itself should be a very fast process unless you are talking about terrabytes of data. So just run the /casalioy/ingest.py with a y flag to create a new vector store. I'll add this onto my watchlist anyways.
