I have exactly the same output as it is expected but I can’t pass the tests. Why?

Hi @anahitkh96,

Welcome to the forums!

This just looks like an issue with a dictionary key. Check the parameters dictionary to make sure you are setting the correct parameters and it contains the key ‘W1’ (maybe you have a typo?)

Hope that helps!
