Week4 i can't run L_model_forward_test(L_model_forward) function

I’m having a bit of trouble with the L_model_forward_test(L_model_forward) function in my notebook. Whenever I try to run the cell with this function, it just hangs and never finishes. But if I just print the output from my L_model_forward function, it works fine and shows the results.

This sort of indicates your code either runs extremely slowly, or it contains an infinite loop.

Thanks, I have already seen the error.
