W4_Ex-9_L_model_backward

I am having issues with Part 1 Porgramming Exercise.

“TypeError: bad operand type for unary -: ‘tuple’”

I’m really lost at the moment.

Hello Posi Olomo,

You are putting the wrong value for current_cache for the last layer. Please check!

Thank you so much. I have been able to pass the exercise. I hope you have a great day ahead.

Glad to know that Posi. All the best.
