Reloading a pybind11 module from Jupyter notebook

[samuelpmish]

Hi,

I've got a pybind11/nanobind project where I'm compiling C++ sources, and using the python bindings from a Jupyter notebook. After doing import my_cpp_bindings in the notebook, if I make a change to the C++ sources and recompile, the Jupyter kernel doesn't seem to detect that the binary my_cpp_bindings.cpython-310-darwin.so file has changed, so the new behavior doesn't take effect. The new binary is used if I completely restart the Jupyter kernel, but I was wondering if anyone has run into this before and has a cleaner solution.

I've tried doing importlib.reload(my_cpp_bindings) and using Jupyter's %autoreload tools, but neither of those approaches seems to work for these .so files-- the Jupyter kernel still has the "old" behavior (but they work great for reloading regular python files).
