in the Machine Learning Specialization Course 2 Module 3 Assignment,
I have found the following “errors”(quoted cuz I’m not sure):
They show the same classification error on cv and train data set. 
There’s a lot of data in those images. Can you highlight (with some markup) exactly what issue you’re asking about?
Indeed, @WONG_Lik_Hang_Kenny, as Tom said, we need you to be more specific about which numbers were confusing you. Although I haven’t run the code myself to verify your numbers, they do look fine.
Let us know.
Cheers,
Raymond
ahh I didn’t read the line carefully, it is fine now
