C1 w3 issue ex2

Hi, i keep having this issue when running this test for excercise 2

I appreciate any suggestion

The error says that your dimensions are not compatible for the dot operation.

I believe, for this exercise, you have to implement the compute_cost function using loops.

For loops are not required.

im not able to fix it, i think i did it using loops? Im still newbie to python. Anyways thanks for your answer

I recommend you attend a course on python and then come back to this course.
