C2W3 Assignment 3

Facing a problem in Assignment 3 of this course even though my codes are correct.
The error that is coming is:
Code Cell UNQ_C1: Function ‘eval_mse’ is correct. Code Cell UNQ_C2: Function ‘eval_cat_err’ is correct. Code Cell UNQ_C3: You have an incorrect value for ‘model’ variable. We expected a value of ‘0’ and you have ‘<keras.engine.sequential.Sequential object at 0x7f3b885fa910>’. Code Cell UNQ_C4: You have an incorrect value for ‘model_s’ variable. We expected a value of ‘0’ and you have ‘<keras.engine.sequential.Sequential object at 0x7f3b88e3dc50>’. Code Cell UNQ_C5: The value of your variable ‘model_r’ is correct.

The grader says your code is not correct. It also tells you which variables are causing the problem.
