Unable to open database file

I am using jupyter notebooks on a MAC and I am unable to open the sakila database. Here is the error message that I got.

OperationalError Traceback (most recent call last)
Input In [6], in <cell line: 1>()
----> 1 conn = sqlite3.connect('data/sakila.db')
3 df = pd.read_sql('''
4 SELECT
5 rental.rental_id, rental.rental_date, rental.return_date,
(...)
19 ;
20 ''', conn, index_col='rental_id', parse_dates=['rental_date', 'return_date'])
