On passing all tests an submitting the lab, I consistently got graded 0% with following error log:
Cell #2. Can’t compile the student’s code. Error: NameError(“name ‘X_train’ is not defined”)
Traceback (most recent call last):

On and off in the lab itself the error will also happen:
–start lab copy: print(“First few elements of X_train:\n”, X_train[:5]) print(“Type of X_train:”,type(X_train)) ---------------------------------------------------------------------------

----> 1 print(“First few elements of X_train:\n”, X_train[:5])
2 print(“Type of X_train:”,type(X_train))
NameError: name ‘X_train’ is not defined
–end lab copy
This pertains to a cell that is out of student’s reach.
