Course 2 -week 1 ,initialisation assignment

I’m getting index error :tuple index out of range when i’m running model on 15000 train examples as in assignment 1,can you please help me to correct this error.

The error i’m getting is after this statement in note book:-

“Run the following code to train your model on 15,000 iterations using zeros initialization.”

Fixed by @Harsha_varun.

There were changes outside the # YOUR CODE STARTS HERE...# YOUR CODE ENDS HERE blocks.

Good luck with the rest of the course!
