Doubt in Week 1 Assignment: Housing Prices

It is the assignment of Introduction to TensorFlow for Artificial Intelligence, Machine Learning, and Deep Learning course but I could not find the specific community for that.
Doubt: my output is correct but it is showing this error:
Failed test case: model has incorrect type.
<class ‘’>,
but got:
<class ‘NoneType’>.

Please move this thread to the right topic.

The function should return the model and not the prediction. Here’s the usage according to the starter code:

model = house_model()

Here’s a link about grader metadata. Seems like you need to refresh your notebook as well.

Thank you. It worked.
