ModuleNotFoundError: No module named 'vtkmodules'

I am trying to run python scikit-surgerytutorial01/sksurgerytutorial01/vtkoverlay_app.py under ubuntu 22.04x64 and got the following error:

Traceback (most recent call last):
  File "vtkoverlay_app.py", line 8, in <module>
    from sksurgeryutils.common_overlay_apps import OverlayBaseWidget
  File "/home/mxochicale/anaconda3/envs/scikit-surgeryvtkVEVE/lib/python3.7/site-packages/sksurgeryutils/common_overlay_apps.py", line 15, in <module>

ModuleNotFoundError: No module named 'vtkmodules'

It seems that scikit-surgeryutils>=1.2.0 install scikit-surgeryvtk v1.1.0, conflicting with the working version scikit-surgeryvtk v1.0.6.

One way to solve this is to downgraded scikit-surgeryvtk to v1.0.6 in the conda environment:

name: scikit-surgeryTUTORIAL01VE
channels:
  - defaults
  - conda-forge #vtk; tox; tbb-devel
  - anaconda #coverage; scipy; pyserial 
dependencies:
  - python=3.7
  - numpy>=1.17.4
  - vtk=8.1.2
  - tox>=3.26.0
  - pytest>=7.1.2
  - pylint>=2.14.5
  - pip>=22.2.2
  - pip:
     - PySide2>=5.14.2.3   #(ci version)
     - scikit-surgerycore>=0.1.7
     - scikit-surgeryutils>=1.2.0 #install scikit-surgeryvtk>=1.1.0
     - scikit-surgeryvtk==1.0.6 #so, downgraded
     - scikit-surgeryarucotracker>=0.1.1
     - opencv-python-headless==4.7.0.68

There are two issues here. vtkmodules is only present in vtk > 9. Your build has installed vtk 8.1.2. So vtkmodules won't be present.
The second issue is that we removed QVTKRenderWindowInteractor.py from our code base at SciKit-Surgery/scikit-surgeryvtk#190, which would have been released at v1.1.0. This seemed like a good idea at the time, but I now realise this will cause problems for people on Ubuntu who can't use vtk 9.x.x.

@mxochicale I have faced the similar issue and solved it using vtk instead of vtkmodules since vtk==8.1.2 have vtk package instead of vtkmodule. In file vtk_overlay_window.py you can use from vtkmodules.qt.QVTKRenderWindowInteractor import
QVTKRenderWindowInteractor. Please try this one.
