Python 3.12 no longer supports calls to PyImport_AppendInittab once initialized. The call was redundant as Blender's `bpy_internal_modules` already includes the "manta" module. Resolve by disabling the call when Python's lifecycle isn't being managed by manta-flow.
Mantaflow
Mantaflow is an open-source framework targeted at fluid simulation research in Computer Graphics. Its parallelized C++ solver core, python scene definition interface and plugin system allow for quickly prototyping and testing new algorithms.
In addition, it provides a toolbox of examples for deep learning experiments with fluids. E.g., it contains examples how to build convolutional neural network setups in conjunction with the tensorflow framework.
