Freezing PyVista with pyinstaller

You can make some fantastic standalone programs with pyinstaller and pyvista, and you can even make a graphical user interface incorporating PyQt5 or pyside2. Depending on your version of VTK, this requires some extra steps to setup.

When running VTK v9, you need to add several additional hiddenimports. For clarity and completeness, create a spec file (we’ll name it pyvista.spec) following the directions given at Using Spec Files. Modify the Analysis and add the following hidden imports:

main_py = os.path.join(some_path, 'main.py')
a = Analysis([main_py],
             pathex=[],
             binaries=[],
             hiddenimports=['vtkmodules',
                            'vtkmodules.all',
                            'vtkmodules.qt.QVTKRenderWindowInteractor',
                            'vtkmodules.util',
                            'vtkmodules.util.numpy_support',
                            'vtkmodules.numpy_interface.dataset_adapter',
                           ],

From there, you can freeze an application using pyvista and create a standalone application.
