When using f2py with a .f90 file, does one have to use the flag !f2py instead of Cf2py? I use the intel fortran compiler and it seems compile to a .pyd file if I use !f2py. If I use Cf2py, it fails. Thanks for your help.

Yes.

It doesn't have to do with f2py, if you are using .f90 the compiler will assume free form, and in free form comments begin only with !. In fixed form they begin also with C.
