create a regression model for the concrete data using keras

[Madeha9]

Hello everyone,,
I'm building my first regression model using keras , and my dataset is the concrete dataset , everything was working perfectly, I excute the code many times by manipulating the number of the hidden layers and the epochs numbers , after a while I started getting an Attribute error message with fit function can you help me please to point where is the error exactly , attached is the code

model.fit fails because the model variable does not store the Model class, but instead it's NoneType class.

We would need to see the full code, or at least were you assign model variable, to debug it

Aren't you missing return model in your regression_model() function?

[Madeha9]

yes you right, I did not add the rentrun model and that was issue , I added the return , the code runs normally .

thank you so much appreciate it
