I’m using vtk python from pip, it is 8.1.2. Unable to find this attribute. Any suggestions? Is this function not available in 8.1.2?

```auto
>>> import vtk                                                                                                          
>>> split_filter = vtk.vtkReebGraphToJoinSplitTreeFilter() Traceback (most recent call last):                                                                                        
File "<stdin>", line 1, in <module>                                                                                   
AttributeError: module 'vtk' has no attribute 'vtkReebGraphToJoinSplitTreeFilter'

```

I’m going to guess that `FiltersReebGraph` is not in that build. Is there a library/module with that name in the package?

No, there isn’t. Any specific reason it was left out in the pip package?

It looks like it uses Boost, so that is likely the reason.
