Hi, I am getting the following message while trying to submit the C5W3 assignment 2 (trigger word detection). The unit tests are all getting passed including the cell being referred to in the error message.
Could someone kindly let me know how to proceed with regards to this?

Cell #UNQ_C3. Can’t compile the student’s code. Error: SyntaxError(‘invalid syntax’, (‘/tmp/student_solution_cells/cell_19.py’, 21, 1, ‘,# UNQ_C3\n’))

Did you download the notebook to work on locally, and then up-load it back into Coursera Labs for grading?
