Wow...I was stuck and was having a hard time getting the the Jupyter notebook to work. Thank you for the walk through, it cleared up all of my confusion. This helped a lot just to watch someone work through the assignment UI. TY!!!

[risingsundance]

could you please type the code in the description of the video to make it easier, it's hard to see in the video and the sound is so muffled it's almost impossible to hear what you're saying at times

I tried your code for exercise 1 and it did not work.

----> 5 cost = compute_cost(x_train, y_train, initial_w, initial_b)
6 print(type(cost))
7 print(f'Cost at initial w: {cost:.3f}')

in compute_cost(x, y, w, b)

24 for i in range(m) :
---> 25 prediction = W * X[i] +b
26 cost = (prediction - y[i]) ** 2

Please help

[siddharthp]

hey your video was had a nice explanation, can you explain all the code

[catsadogga]

I have taken the course, the explanations are great, but he's not teaching the code, we should only do it in the assignments, what should I do to learn the coding part?
