A friend and I have been toying around with various Python C++ wrappers lately, trying to find one that meets the needs of both some professional and hobby projects. We've both honed in on PyCxx as a good balance between being lightweight and easy to interface with while hiding away some of the ugliest bits of the Python C api. PyCxx is ...
Hi. I would like to convert numpy array to some double* or stl vector on the c++ side. I'm actually using PyCXX for this and I can't figure out the way to access the data. I'm currently able to access and return the data buffer like this : Py::Object arrayShape(const Py::Tuple& args ){ Py::Object array= args[0]; return arra...

I can't see an obvious way of constructing an instance of B from within C++ code. The constructors of new style classes require a PythonClass...
