On hyperparameter tuning for Course 1 week 4 assignment

Hi mentors,
Maybe I’m out of luck but I’ve been tuning the hyperparameters for Course 1 week 4 assignment - Happy or Sad data, but still can’t reach the callback’s 99.9% accuracy.

Appreciate if I could forward the code to you for review? Thank you.
