SQLAlchemy is using unixODBC to connect to Vertica. You need to install the drivers and set up a DSN

You should be able to connect with these parameters. This is what worked for me in my previous SQLAlchemy / Vertica project. Also, if this doesn't work, I would make sure it is configured properly and that you can connect using isql (comes with unixODBC).

drivername='vertica+pyodbc',
username='myuser',
password='mypassword',
host='hostname',
database='DBNAME',

You can also do this for a DSN connection:

engine = create_engine('vertica+pyodbc://username:password@mydsn')
