Expected behavior:  
Actual behavior:

Hi,everyone. These days i am trying to get leap motion to work with Slicer, and i attended to add an old module python code to 3D slicer, then i have this problem -----ImportError: No module named ‘LeapPython’ , so i search for solution on Internet. It turns out that i need older python version(i.e 3.3.0),therefore i would like to ask “is there a way to change the python version (now is Python 3.6.7) on slicer 4.11.0 to old python version?” .Any help would be appreciated .

We recently discussed what is missing to add support for Leap motion. In a nutshell, the bindings available with the v3.2 of Leap motion SDK would need to be re-generated and compiled for python 3.

This is discussed at length in this post: [SlicerLeapMotionControl in Slicer 4.11.0](https://discourse.slicer.org/t/slicerleapmotioncontrol-in-slicer-4-11-0/6770/10)
