Cannot open VTK output file

[cgw]

Thanks Jeff - right, I meant to type python -c "import vtk", thanks for the correction.

What’s interesting to me about this traceback is that it doesn’t mention tbb, it’s different from the error that was reported at the beginning of this thread.

Could not import VTK, please check your installation.
traceback:

During handling of the above exception, another exception occurred:

It doesn’t mention any particular DLL (it could still be libtbb but we don’t know) and the error is different:

The first one:

 ImportError: DLL load failed: The specified module could not be found.

The new error Dillon reported:

 ImportError: DLL load failed: The specified procedure could not be found.

“Specified module” vs “specified procedure” - I
It would be helpful if the error message told us which module or procedure!
I think “the specified module” error means a file is missing, while the “specified procedure” means that the file is found, but there are unresolved external symbols.
