SubConverterFileIOException - music 21 show()

Question

I just installed music21, and I'm trying to get started on it. I have Musescore3 installed, but I can't make the show() funcion work.

I've tried changing the paths, following some instructions I found online, but to no avail

from music21 import *

us = environment.UserSettings()
us['musicxmlPath'] = 'D:\\Program Files\\MuseScore 3\\bin\\Musescore3.exe'
us['musicxmlPath'] = 'D:\\Program Files\\MuseScore 3\\bin\\Musescore3.exe'

I'm trying to do a simple show()

from music21 import *

f = note.Note('F5')
f.show()

Here's the error I got:

SubConverterFileIOException: png file of xml not found. Or file >999 pages?

Answer 1

I have encountered this situation, Because you can't use Musscore3 when you run on jupyter. Try run with terminal it can work
