@shavejshaikh I think you just need to update your fork to the latest code in this main repo. Your stacktrace shows the error coming from async with self._async_session() as session: on line 43 of pg_vector.py. As you can see in the latest code here, we've since added a call to self._initialize() that sets up these session variables. Let me know if that fixes your error!

@sourabhdesai After update pg_vector.pygetting error AttributeError: 'CustomPGVectorStore' object has no attribute '_initialize'

@sourabhdesai , now getting DETAIL: Could not open extension control file "/usr/share/postgresql/16/extension/vector.control": No such file or directory. Created env using conda and install dependency using poetry

Any idea ?

Found the solution since pgvector isn't install along with postgres (Ubuntu).

1. Check postgres version postgres=# SHOW SERVER_VERSION;

2. Install pgvector based on above postgres version sudo apt install postgresql-16-pgvector Change 16 based on your postgres version
