Flask-SQLAlchemy import error. "Imported but unused" : <p>I used sqlacodegen to extract the a .py file containing classes of my db tables. I am using pythonanywhere. However for all the imports it is showing that "imported but unused".</p>

<p>You can see though column has been used, it shows the sqlalchemy.Column imported but unused.</p>

<p>Am I doing anything wrong here?<a href="https://i.stack.imgur.com/ow4H0.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ow4H0.png" alt="Imported but unused"></a></p>
