muscima (Music Score Images) package implements a data model for the MUSCIMA++
dataset of music notation.
This package should work with both Python 2.7 and Python 3.6, although the doctest-based test suite only works on Python 3.
The dataset itself is available for download here and due to its derived nature, licensed differently:
mung (Music Notation Graph) package is the successor of this project,
updated to accommodate MUSCIMA++ v2.0 and with lots of improvements, such as
performance enhancements, a more consistent naming convention, class-names
that are close to SMuFL and type hints.
More information can be found here. For future updates and improvements, consider migrating to MuNG.
