These warnings can be ignored. 

The first one means that Event derives from ublas::vector, but SWIG does not know how to generate Python wrapper code for ublas::vector. I tried to get SWIG to wrap this with the recommended %template directive, but it didn't work. I probably could have succeeded with more work, i.e. by writing some additional typemaps, but I settled for adding a few convenience functions instead.

Similarly for Midifile. In this case, it would have been pretty easy to wrap std::map as SWIG can do that with the recommended %template directive, but there was no particular reason to wrap it, Python programmers don't need this level of access here.

Regards,
Mike
