C2_W4 assignemment Exercice 5:gradient descent / gradient_descent() function problem

Hi everyone;i hope you are doing well i have a problem with my gradient descent as it shows “inf” costs in iterations (all the previous tests work successfuly):Call gradient_descent
iters: 10 cost: inf
iters: 20 cost: inf
iters: 30 cost: inf
iters: 40 cost: inf
iters: 50 cost: inf
iters: 60 cost: inf
iters: 70 cost: inf
iters: 80 cost: inf
iters: 90 cost: inf
iters: 100 cost: inf
iters: 110 cost: inf
iters: 120 cost: inf
iters: 130 cost: inf
iters: 140 cost: inf
iters: 150 cost: inf
this is my function:

Check the compute_cost function, I saw at lease a parameter there placed in wrong position!
