Hi @Jing_Chen ,

It could be the the bias term is added within the 2nd ‘for’ statement, so please make sure it is outside of that ‘for’ statement. Because, the 2nd ‘for’ statement is to loop through all the features of one sample. The bias term should only be added after that.
In Python, indentation is used to structure code block. Incorrect indentation would bring about the wrong logic to the code.
Also, double check your code against the Hints to ensure the logic is correct
