Python 3.7.0 problem; possible 3.8.0 API change
In Python 3.7.0, calling
Py_Initialize and then
Py_Main (as vtkPythonInterpreter does) causes a crash (to be fixed in Python 3.7.1). However, this usage pattern appears mildly frowned-upon and the original Python issue also links to these:
which we should track since there may be API changes in 3.8 after the 3.7.0 regression is fixed.
See this Discourse discussion for the original problem.
