"Model" incorrect value

I keep the following errors.
Despite the fact that my notebook runs fine, I get the following reply in my grade for the C2_W3_Assignment.
How can I solve it?

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 0x7f0ff6a4f090>’.
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 0x7f0ff5dfdc10>’.
Code Cell UNQ_C5: You have an incorrect value for ‘model_r’ variable. We expected a value of ‘0’ and you have ‘<keras.engine.sequential.Sequential object at 0x7f0ff5224050>’.

Hi!

Can you send me your code a direct message so I can help?
I’m unable to figure out the problem from the errors alone.

Already solved.

I modified the Learning Rate and it is accepted now.
