I’ve passed all test in assignment but it is not being graded and marking errors like “transformer not defined” and “grader error:grader feedback not found”. Anyone else?
these kind of grader is usually given when a learner has made any beyond changes in grade cell codes like removing Grade function header mentioning transformer or making any changes outside the marker ###START AND END CODE HERE###
Grader submission even fails when you have made changes between these markers and not follow the already given instructions to write the codes.
So in case if you have done these changes, then you need to get a totally fresh copy and re-do your assignment, by making sure only to write codes as per instructions already given in the grade cell without deleting or editing which was already given at the beginning of opening an assignment notebook.
