I was doing the the assignment lab at the end of week 2.
The first half is to compute cost. This seemed fairly straitforward.
As it’s shown on first screenshot.
However the next box test code keep failing me
AssertionError Traceback (most recent call last)
in
9 # Public tests
10 from public_tests import *
—> 11 compute_cost_test(compute_cost)
~/work/public_tests.py in compute_cost_test(target)
17 initial_b = 1.0
18 cost = target(x, y, initial_w, initial_b)
—> 19 assert cost == 2, f"Case 2: Cost must be 2 but got {cost}"
20
21 # print(“Using X with shape (5, 1)”)
AssertionError: Case 2: Cost must be 2 but got 32.0
I know I would be told that means you have wrong calculation in your code but I checked multiple times. I went through all hints and cost calculations optional lab of week1.
My code is identical line to line. Like I said the assignment is pretty straightforward with only two formulas. And I’m familiar with Python for 10 years by now, including using it at work periodically.
This is pretty frustrating and I’m not sure which way to troubleshoot now.
Any help is hugely appreciated.
