Draft:try to pass id (!2) · Merge requests · Jakob Roth / Extending Jax and NIFTy

Jakob Roth requested to merge pass_id_to_cpp into master Nov 30, 2023

I tried to pass the information about the array shape via a Python ID to C++. Nevertheless, since I am not really familiar with C++, I couldn't figure out how to get the Python object back from the ID.

More specifically, the input to the C++ function is now two void pointers. The first points to the ID of a NumPy array containing the dimensions of the input (second pointer). @mtr do you know how to get back the numpy array from the id?
