Hola ! Even though the Output of predict value is as expected (_Function ‘predict’_), I got this point incorrect. That causes me less earn points to pass. Would you mind helping me to figure this point out? ### mlsc1w3-ex1 _Code Cell UNQ\_C4: Function ‘predict’ is incorrect. Check implementation._ Thanks! ---

Hi Carlos, Please share your code for UNQ\_C4 on Direct Message 🙂 I can take a look! Raymond ---

Hello Carlos, Seems you used both the vectorization approach and the for-loop approach to double calculate `z_wb`. Please see if this is the problem? Cheers! Raymond ---

Hi @rmwkwok, I have the same problem as Carlos but I think that I implemented z\_wb correctly. I can’t find a solution that solves my problem on other posts. Can I send you my notebook on Direct Message please ? Dalila ---

Hi @Dalila, is your problem about UNQ\_C4? If so please send me the code for UNQ\_C4 first on direct message, I will ask for the notebook if needed. ---

Thank you @Dalila, there is a problem in the line for adding bias, please check if you need “+=” or “=”. Raymond ---

I see. I suggest you to use 4 white spaces for one level of identation. For example: `def predict(X, w, b):` is in the zero-th level of indentation, so you don’t need any white spaces before it. Anything inside the `predict` will be **at least** in the first indentation level which will all be indented by at least 4 white spaces. You have two for-loops. Anything inside the outer for-loop will be in the second indentation level which takes 8 white spaces. Anything inside the inner for-loop will be in the third indentation level which takes 12 white spaces. To set all lines to zero-level, select those lines, press “Shift + Tab” once and it will go 4 white-space backward, you can keep pressing it until all go back to the zero-th level, then select the lines you want to move one indentation level up, and press “Tab”, and repeat this step until all indentations are alright. ---
