KeyError in autotrack.py

[YoussefFathi]

While running auto_track.py on the generated keypoints3D, I'm getting the following error when setting the Window Size to specific sizes (like 10 in this example). I'm not sure how the logic of the tracking works, so I'm having difficulty tracing the reason behind this error. This error doesn't happen if I set the Window Size to 15, but it happens with most other window sizes.
