Hello, I am getting error while executing unit test function compute\_cost\_test(compute\_cost). It is giving below error. AssertionError: Wrong output. Expected: 2.15510667 got: 2.75932426268233 Also, output of compute\_cost is coming as 0.218 while expected output is 0.219 Its strange that compute\_cost function is working well for me with Cost at initial w (zeros): 0.693 This notebook may have other issues as I was reading another post where it was mentioned that err variable was not needed there. ---

I’ve no clue. But you can check the solutions in the Lab Files (top right) to compare as well as the hints. But yeah, the course is really new. As of right now the 3rd course of this ML specialisation, on Unsupervised Learning hasn’t been uploaded yet so there are bound to be some errors – re: typos and other weird little artifacts ---

Kindly ignore this issue. I was using regularized term unnecessarily. There was lambda parameter given in the function definition which caused confusion. ---
