I use 3D slicer extension VMTK to extract the centerline and do diameter analysis. I use my own STL file and follow the guidelines in youtube. But I got: **Failed to compute results: VMTK library is not found**.

I also tried to use VMTK only in mac m1. It looks like there is a compatible issue. I cannot even open VMTK on mac pro with m1 chip. It works in other macs.

VMTK should work well on M1. This is just a packaging error impacting both Intel/M1 macs:

> <https://github.com/vmtk/SlicerExtension-VMTK/issues/37>
>
> The extension installation package does not contain VMTK binaries, only the Slic…er module .py files, for both latest Slicer Stable Release and Slicer Preview Release on macOS.
> 
> It seems that the recent upgrade to VTK9 broke packaging for VTK-8.2.

@jcfr could you give us an estimate about when this issue will be addressed?

This has been fixed in [COMP: Update VMTK to fix packaging of Python libraries on macOS by jcfr · Pull Request #45 · vmtk/SlicerExtension-VMTK · GitHub](https://github.com/vmtk/SlicerExtension-VMTK/pull/45)

Tomorrow preview build should confirm it works as expected.
