Debugging of python code called from C++

[vp77an]

Is there a solution for debugging python code called from C++ via pybind11?

I know that the opposite works, e.g., based on https://nadiah.org/2020/03/01/example-debug-mixed-python-c-in-visual-studio-code/. I also tried to apply the approach described there to the case of C++ code calling python code, but I can't seem to manage to get it to work if I start the C++ debugger first and then attach the python debugger as described under the above link; the python debugger can't connect to the process.
I have been working with windows10->WSL->Ubuntu20.04 using VS code, but basically any solution that works under linux would be fine. (Visual Studio, which seems to support this, is unfortunately not an option for me.)

Thanks!
