I have similar issue. Slicer starts fine but unable to see any simple filters.

 ![SimpleFilters%20error](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/3/8/3880f1cff52e51ce9fdb8a4c26fed764e86e5a95.png)

The dropdow menu under filters does not work and also the search field.

Confirmed. SimpleFilters module needs to update the [following line](https://github.com/SimpleITK/SlicerSimpleFilters/blob/12efaabb0151c270e61bc7a3b3d08ad4c8db8095/SimpleFilters/SimpleFilters.py#L105) to support Python3 which is now used in Slicer.
