Can’t compile the student’s code. Error: ValueError (‘Could not interpret optimizer identifier: None’)

Tried Reboot but didn’t work

Does it run correctly when you run it locally in the notebook? Meaning that you only get that error from the grader? How many places in your notebook do you reference an optimizer? That’s where you need to look.

Also please note that you haven’t given us any indication of which assignment you are talking about other than that it is in Course 4. Not much to go on …

Problem Solved. Thank you :slight_smile:
