The Anaconda package probably doesn’t enable the VTK-m algorithms.
That’s unlikely to help here. VTK needs to be built with VTK-m support (what you see in the Python code is the VTK-m-using VTK algorithms, not VTK-m itself).
VTK-m is a related, but separate project. If/when they move is up to the developers of VTK-m itself.
