The pypi package works fine for this with vtk as a dependency, but note that we only want to make use of VTK, not provide a superset of functionality that exposes all of VTK, like PyVista or Mayavi.

That’s totally fair

@pieper

On investigation, as shown in this notebook , even though we are only using a couple reader/writer classes we end up pulling in 327 megabytes of VTK libraries.

I can’t access that notebook to see the full details… however…

I’d propose not using VTK if you’re only using for file IO. There are plenty of alternatives like meshio that will likely meet your needs and is pure Python. After all, VTK is a visualization framework and you should only pull it into your stack if leveraging it for viz. Otherwise, I’d highly recommend pursuing other libs for your task to keep your stack lean and clean.
