i try install the server,have the same error

`
import infinity_embedded

# Connect to infinity
infinity_object = infinity_embedded.connect("infinity.db")
# Retrieve a database object named default_db
db_object = infinity_object.get_database("default_db")
# Create a table with an integer column, a varchar column, and a dense vector column
table_object = db_object.create_table("my_table", {"num": {"type": "integer"}, "body": {"type": "varchar"}, "vec": {"type": "vector, 4, float"}})
# Insert two rows into the table
table_object.insert([{"num": 1, "body": "unnecessary and harmful", "vec": [1.0, 1.2, 0.8, 0.9]}])
table_object.insert([{"num": 2, "body": "Office for Harmful Blooms", "vec": [4.0, 4.2, 4.3, 4.5]}])
# Conduct a dense vector search
res = table_object.output(["*"]).match_dense("vec", [3.0, 2.8, 2.7, 3.1], "float", "ip", 2).to_pl()
print(res)
