Why Slicer can not instantaine for example vtkvmtk, curveMarker other many issues. The messages are the following ones:
Failed to load vtkSlicerCrossSectionAnalysisModuleLogicPython: No module named vtkSlicerShapeModuleMRMLPython
Failed to load vtkSlicerStenosisMeasurement3DModuleLogicPython: No module named vtkSlicerShapeModuleMRMLPython

Regarding CurveMaker:
>
>
> Since introduction of curves in Markups module and MarkupsToModel extension, the… CurveMaker extension became redundant.
>
> Recent rework of the Endoscopy module in Slicer core, the extension has been reported to not work anymore - see https://github.com/Slicer/Slicer/issues/7519
>
> Instead of fixing the extension, I would recommend stopping development and support of the extension for Slicer-5.7 and later.
Regarding vtkvmtk message:
>

> This error is reported at Slicer startup if SlicerVMTK extension is installed:

In what version of Slicer are you seeing that? I just checked in a self-built Slicer and they are not apparent. I remember that it was [resolved](https://github.com/Slicer/Slicer/commit/9c875033632aea198791c0960310c165cad487c4) of old.
