Hello,

I am struggling with the graded practice lab. I have followed the hints and the coding, but I am getting a 0% correct when I go to submit the lab. I look at the test code result, it is unclear where my issue is. Here is an example:

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 0.5

here is my actual coding:

```
# UNQ_C1
# GRADED FUNCTION: compute_cost
def compute_cost(x, y, w, b):
# moderator edit: code removed
```

Can someone take a look and provide some guidance? I have similar issues on the gradient descent problem.

This is all new to me and I do not have a very clear understanding yet.

I appreciate everyone’s time and assistance.

Best regards,

Rich Kline
