local postgres #120

Open magaton opened 1 month ago

magaton commented 1 month ago

I see postgres is started in docker. How can I disable that and use my local Postgres, running as Postgres.app?

Anyway, with postgres started in Docker (regular setup) I am getting the following exception: ModuleNotFoundError: No module named 'sqlmodel'

I have sqlmodel declared as dependency in pyproject.toml. I am running the same langgraph from command line without a problem,

Any idea? Thanks

Here is the stacktrace:

Anyone?

Hello @magaton! Will take a look

magaton commented 1 month ago

Any thoughts?

magaton commented 1 month ago

Hi, @dqbd have you had a chance to look at this issue? I would like to know whether it is a bug or a feature (desired behaviour) so I can decide whether to use langgraph studio, or not. Thank you!
