Exception on loading a music xml file

[GitterHubber]

Windows 7, x64 system with python 3.6.

I get an exception after loading a XML file. The program first prints the following

Your hand span set to size-M which is 17.22 cm

and then throws an exception

I have attached the xml file that causes this error. Any pointers to this would be very helpful. TIA

@GitterHubber As your score only has the right hand beam you should untick the left hand in the GUI:

or if using the command line: pianoplayer -r hb.xml

Note that the file extension should be .xml

Thanks, for the info, I just saw the score images that you attached the last few notes don't seem to be numbered, is this by design?

[marcomusy]

yes, it's by design: there are not enough "future" notes to make a valid prediction at the end of the score.
