How to debug debug Pybind11 wrapped CUDA code in DROID-SLAM #74

would it be possible to ask what tools that use to debug Pybind11-wrapped CUDA code in DROID-SLAM? I have tried cout something in cuda code in DROID-SLAM but it doesn't show in the console so I want to ask how to debug CUDA codes which are called by the python script?

you need to call printf in the cuda function. It is very annoying because you need to build it every time you change the code.
