Where to Log

By default, all data is logged to the current working directory to default.sqlite (sqlite:///default.sqlite). Data can be logged to a SQLAlchemy-compatible referred to by database_url in the format dialect+driver://username:password@host:port/database.

See this article for more details on SQLAlchemy database URLs.

For example, for Postgres database trulens running on localhost with username trulensuser and password password set up a connection like so.

from trulens_eval import Tru
tru = Tru(database_url="postgresql://trulensuser:password@localhost/trulens")

After which you should receive the following message:

🦑 Tru initialized with db url postgresql://trulensuser:password@localhost/trulens.
