How to generate Python modules using f2py

For conventional Fortran code, there is no problem to generate Python modules using f2py:
f2py -c fortrancode.f90 -m moduleName
However, I have no idea how to generate a Python module for Cuda Fortran code.
I had tried : f2py --verbose --fcompiler=pg -m moduleName -c cudaFortranCode.cuf
Anyone can help me on this? Thanks a lot!
