Your system has an unsupported version of sqlite3. Chroma requires sqlite3 >= 3.35.0

I'm running a flask api to talk to my pdf at the code level, but it's giving me this error:

The imports I use are:

from flask import Flask, request, jsonify, make_response, send_file
import os

Glad to hear you got that working!

Hi @payconautomacoes How did you do that in pythonanywhere?

this might be from a recent upgrade of Langchain it was working here before, but not anymore, I note that there are some options in the webpage, but Is not quite clear for me as a hobbyist

I think you're right; our most recent system image has SQLite version 3.31, so if you're getting an error from Langchain saying that it needs a more recent version, but it did work before, then it's likely that Langchain have made a new release that's causing the problem.

I've done a bit of digging around on Google, and if the error you're getting relates to Chroma, it might help if you try running

 pip install pysqlite3-binary

Could you let us know if that helps?

it does work, this solves the issue, thanks so much

the problem is that previous database files using previous versions of Chroma don't work anymore

For software that relies on a backend database, there is usually a way to upgrade databases from old versions. Check the Chroma documentation to see if there is a way to upgrade the database.

No this does not solve the issue

Then perhaps the old database is just not useable.

any updates on this?

Hey im running in the same error but the command pip install pysqlite3-binary does not work, even if i paste the following in my projects init file: import pysqlite3 as sqlite3

How the command pip install pysqlite3-binary fails for you?
