The code works properly but when I submit the assignment it throws an error about the
Failed test case: prediction is NOT close enough to 4.0 for houses with 7 bedrooms.
Expected:
a value close to 4.0 (with absolute tolerance of 0.05),
but got:
400.5941162109375.
Eventhough the code is running correctly, getting grade 0. Getting error as ‘Keras’ not defined. Have already imported Keras and not getting any error while running.
