C2_W2_problem with preprocessing_fn

Hey guys, I keep getting 'name ‘preprocessing_fn’ is not defined" even after running the cell several times. Anyone had the same problem?

Hi! Welcome to Discourse! I don’t think I’ve encountered this before. Can you post a screenshot of where you are getting this error? If it helps, you can use the ungraded labs for reference on how the commands should be run. Perhaps you missed a few details that’s why it’s throwing the error in the assignment. Hope this helps!
