C1W1_Assignment final model function problem

In the section define output layers of the model, in the final_model function there is a problem. In the wine_quality line as it does not have any activation function, an attribute error is being thrown.

@bhanukrishna, test_final_model is checking for problems in your implementation of final_model. From the stack trace, it looks like your implementation of final_model is returning None instead of the model.

Please go back and check your implementation of final_model. Did you uncomment all the lines in the cell and fill in your implementation for all the places that say, # YOUR CODE HERE? You can read the instructions above the cell for details of what your implementation should do.
