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.

Debugging
You could export openVDB volume into mantaflow, by running Blender with:
blender --debug-value 3001
And then select Domain -> Fluid -> Cache - > Advanced -> Export Mantaflow Script.
