Cell #8. Can't compile the student's code

Hello team. I have submitted week2 lab assignment: linear regression. But It fails and the grader reports this Error:
“Cell #8. Can’t compile the student’s code. Error: SyntaxError(‘invalid syntax’, (‘/tmp/student_solution_cells/cell_8.py’, 10, 7, ‘np.sum??\n’))”

There were two exercises in this lab and i passed them.

Did you rename your notebook file? The grader doesn’t like that. It always grades the default notebook name.

Did you insert that code someplace in the notebook in order to get the documentation for np.sum? Looks like the grader is not able to handle that. The solution should be pretty easy. :nerd_face:

Thanks, the issue was resolved

Thanks! I removed the “np.sum??” and it worked
