[vtkusers] Pip install vtk for Python 3.x

[B.J. Hulsey]

Thank you. I am using sudo which only had access to the Python 2. However,
I am gettting a GL dirver error with when I run vtk under Python 3.

Can you recommend current compatible LLVM and MESA versions for OpenGL2
backend?

Running a simple example <http://Started the transfer for Halcon Sealy
Ranch Jdays 147-151 To /processing/rawdata/Halcon/Sealy-Ranch/shipment2/ If
the transfer doesn’t finish before our network maintenance tonight I will
resume it after the maintenance is done.>, I get:

Local terminal

vtkXOpenGLRenderWindow (0x2029d00): GL version 2.1 with the gpu_shader4
extension is not supported by your graphics driver but is required for the
new OpenGL rendering backend. Please update your OpenGL driver. If you are
using Mesa please make sure you have version 10.6.5 or later and make sure
your driver in Mesa supports OpenGL 3.2.
