I didn't see this error before. But you can delete the .pyc file. .pyc files are "python byte code" and derived from the .py file with the same name. If you delete the .pyc file, python will recreate it from the .py file – hopefully without the magic-number error. In case you wonder what python has to do with this: convert-ly is written in python. Hope that helps, Joram _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
