Import "pgvector.psycopg" could not be resolved

I am getting this now. Installed pgvector and psycopg3

Mac OS psycopg 3.2.2 vector extensions is enabled and works from pgAdmin in Postgres

This is the code. I haven't gotten anything to work so far.

import psycopg import numpy as np from pgvector.psycopg import register_vector

with psycopg.connect("postgresql://xxx:xxx$@localhost:5432/xxx") as conn:

conn.execute('CREATE EXTENSION IF NOT EXISTS vector')

register_vector(conn)
conn.execute('CREATE TABLE items (id bigserial PRIMARY KEY, embedding vector(3))')
# https://github.com/pgvector/pgvector-python/issues/4 <-- tried everything from here.

embedding = np.array([1, 2, 3])
conn.execute('INSERT INTO items (embedding) VALUES (%s)', (embedding,))
conn.execute('SELECT * FROM items ORDER BY embedding <-> %s LIMIT 5', (embedding,)).fetchall()

pgvector / pgvector-python
