My exercise get graded 0 in all its exercise, the message error that I have is:“There was a problem compiling the code from your notebook. Details:
name ‘feature’ is not defined”
There are lots of ways that the grader can give you a score of 0. Sometimes the error message it gives is very confusing.
But let’s start with the basic checks:
Perhaps you used the variable name “feature” where it was a global variable. That will break the grader. Check for each place in your notebook where you might have used a variable named “feature”. When you used “feature” was it a local variable, or a global variable?
Did you ever add any new cells to the notebook?
Did you ever delete a cell from the notebook, and then try to re-create it?
Did you add any code to the notebook outside of the area marked “START CODE HERE”? The grader really does not like unexpected changes to the functions.
