The package struture is:

rtmidi/
    __init__.py
    _rtmidi.so
    release.py

and the symbols from the _rtmidi module are imported into the package
namespace in __init__.py.

The _rtmidi.so file is the C extension compiled from the C source file
rtmidi.c generated from the Cython file _rtmidi.pyx (in the src
directory of the distribution).

I can't say why you got this without more detail, but if you follow the
installation instructions in the README and have all the dependencies
you should be ok.
