ValueError: You are using a deprecated configuration of Chroma.

If you do not have data you wish to migrate, you only need to change how you construct
your Chroma client. Please see the "New Clients" section of https://docs.trychroma.com/migration.

If you do have data you wish to migrate, we have a migration tool you can use in order to
migrate your data to the new Chroma architecture.
Please pip install chroma-migrate and run chroma-migrate to migrate your data and then
change how you construct your Chroma client.
