This is windows specific and relates to the VTK Master.

If VTK_SMP_IMPLEMENTATION_TYPE is set to tbb then when using PyCharm we get the following error:

C:\Users\amaclean\Miniconda3\envs\VTK\python.exe D:/Users/amaclean/Development/Kitware/src/vtk-examples/src/Python/Visualization/CurvatureBandsWithGlyphs.py

    from . import vtkCommonCore
ImportError: DLL load failed while importing vtkCommonCore: The specified module could not be found.

During handling of the above exception, another exception occurred:

During the build lots of warnings warning C4324: 'tbb::detail::d1::task': structure was padded due to alignment specifier are generated for the VTK C++ classes and the Python wrapping.

If VTK_SMP_IMPLEMENTATION_TYPE is set to sequential then there are no issues with PyCharm.

Note that a command such as:

python D:\Users\amaclean\Development\Kitware\src\vtk-examples\src\Python\Visualization\CurvatureBandsWithGlyphs.py

works Ok in both cases, so it seems to be some issue with PyCharm, probably triggered by this commit: 514578f5

I am using oneapi-tbb-2021.1.1, PyCharm 2020.3.5 (Community Edition), Python 3.9.2. I have invalidated caches and restarted PyCharm, also removed all plugins. The virtual environment that I use hasn't changed and was working OK.
