Hello,

I am Toufiq Aziz. There is an error in the Supervised Machine Learning: Regression and Classification third week’s assignment which is unable to edit. Here is what the error says.

TypeError Traceback (most recent call last)
in
5 initial_b = 0.
6 cost = compute_cost(X_train, y_train, initial_w, initial_b)
----> 7 print(‘Cost at initial w and b (zeros): {:.3f}’.format(cost))

TypeError: unsupported format string passed to NoneType.format

Hi @Toufiq_Aziz,

It seems like the function compute_cost is returning None to the variable cost that’s why formatting on None won’t work. Try to print the variable cost.

To edit any cell select View on menubar → Cell ToolBar → Edit Metadata and Change the key editable to true.

I have tried to change the code but I already mentioned that the code is uneditable, specifically in that part of the coding.

Hi @Toufiq_Aziz,

Please double check your implementation of compute_gradient function.

You can use the provided hints in the lab notebook for the guidance.
