The error:

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
File "scripts/get_motion_maps.py", line 66, in

In my understanding, this happens when some paths are incorrect. But I cannot figure out what is wrong. Any help is appreciated.

Thanks
