Some of you encountered difficulties installing PILLOW. Most problems had to do with mismatching word lengths (32 / 64 bit) of your Python version and the PILLOW version.
For those of you who are still struggling: check first that Python and PILLOW are both 32 bit or both 64 bit (Python version is written at the top of the window when you open IDLE).
Additionally, verify that the file matrix.py from class (also appears in the recitations) is located at the same directory as the skeleton5.py you are working on.
To compensate for the waste of time caused by this technical issue, we extend HW5's deadline until the last day of the semester, Sunday 25/1 at 23:55.
