Course 1 Week 2 programming assignment, cost function question

I wrote my answer like below but can’t figure out why it is not correct. Can someone help please? thanks a lot


The error was

<class 'numpy.float64'>
Cost at initial w: 377446.185
AssertionError                            Traceback (most recent call last)

~/work/ in compute_cost_test(target)

     10     cost = target(x, y, initial_w, initial_b)

y_hat = w*x+b

not x*m + b

The weights are w.
The number of examples is m.

Hi, @xy_ds Just replace the “m” with “w” and you should probably get the desired result.

Lab is not working


It has been more than a week that my lab is not working. I have to finish the assignments for which lab practice must be done. How can I fix It?

Kindly help me.
