Problem with packages vtkvmtk and pypes

I am working with a script that imports vtkvmtk and pypes but I keep getting the following error message:

No module named ‘vtkvmtk’

how can I remedy this? Can I install these packages? If so, from where?

The best way to do it if you are using Slicer is to call the extensions manager from the python interactor and install the vmtk extension

I don’t think I quite understand what you mean, sorry

The vmtk extension installed will let you import the code you want

@19lollo95 do you use VMTK in 3D Slicer’s Python environment or you install it to some other Python environments using pip or conda?
