So, the format for musicologist and researcher in music is the MEI format: https://music-encoding.org/ for which the reference engraver is verovio: https://www.verovio.org/index.xhtml Note that verovio is able to engrave in svg format while keeping a maximum of information from the original mei score, meaning that you can extract enough metadata to create an actual detection dataset for a deep learning model. This is my horrible hacked up script that will create a coco dataset from a set of scores engraved with verovio: https://github.com/kwon-young/music/blob/main/svg2pl.py I have published a synthetic music score dataset from this: https://www.kaggle.com/datasets/kwonyoungchoi/trompa-coco/da... I anyone wants to try and fit a detector on top is welcome :)

To understand why OMR is so neglected is because most people widely underestimate the difficulty of the task. It has a specific blend of the most extreme shapes combined with an extremely complicated graphical grammar...

It's nice that python 3.15 added Iterator synchronization primitives: https://docs.python.org/3.15/library/threading.html#iterator.... These will nicely complement my threaded-generator package which is doing just this but using a thread/process+generator+queue: https://pypi.org/project/threaded-generator/

The article mentions prolog but doesn't mention you can use constraints to fully express his computation graph. My prefered library is clpBNR which has powerful constraints over boolean, integers and floats:

  Welcome to SWI-Prolog (threaded, 64 bits, version 9.2.9)

  ?- use_module(library(clpBNR)).
  % *** clpBNR v0.12.2 ***.
  true.
  
  ?- {TotalOwed == TotalTax - TotalPayments}.
  TotalOwed::real(-1.0Inf, 1.0Inf),
  TotalTax::real(-1.0Inf, 1.0Inf),
  TotalPayments::real(-1.0Inf, 1.0Inf).
  
  ?- {TotalOwed == TotalTax - TotalPayments}, TotalTax = 10, TotalPayments = 5.
  TotalOwed = TotalPayments, TotalPayments = 5,
  TotalTax = 10.

If you restrict yourself to the pure subset of prolog, you can even express complicated computation involving conditions or recusions. However, this means that your graph is now encoded into the prolog code itself, which is harder to manipulate, but still fully manipulable in prolog itself.

But the author talks about xml as an interchange format which is indeed better than prolog code...

I don't see the advantage ?

In the comparative table, they claim that conda doesn't support:

* lock file: which is false, you can freeze your environment

* task runner: I don't need my package manager to be a task runner

* project management: You can do 1 env per project ? I don't see the problem here...

So no, please, just use conda/mamba and conda-forge.

In my opinion, anything that touch compiled packages like pytorch should be packaged with conda/mamba on conda-forge. I found it is the only package manager for python which will reliably detect my hardware and install the correct version of every dependency.
