C1_W3_Exercise 3 Error

are you still getting the same error?

Did you read the whole post, I mean the following comments??

Sending you one more hint link

probably your dj_db and dj_dw has some issue, please check this

I want you to try working on this error for while and solve by yourself.
I promise If you still do not get, I will look into the code. By the time, you can share your notebook via personal DM as we are not suppose to share graded cell code on public posts.
