ImportError: cannot import name 'MutableSequence' from 'collections'

[Winter-Sno]

Expected behaviour

I want to do onset detection in a classical music piece.
I expect the program to return an arraylist like [1,2,3,4,...] marking the onset timestamp of each note.

Actual behaviour

The program did nothing and an error like this occurred. (╥﹏╥...)

Traceback (most recent call last):
  File "D:\workspace\SRT_simulation\madmom_note_extract.py", line 1, in <module>
    import madmom

    from collections import MutableSequence
ImportError: cannot import name 'MutableSequence' from 'collections' (D:\anaconda3\Lib\collections\__init__.py)

Steps needed to reproduce the behaviour

import madmom

filename = '01.Overture.flac'


def madmom_get_note_map(filename):
    proc = madmom.features.onsets.CNNOnsetProcessor()
    proc(filename)


if __name__ == '__main__':
    madmom_get_note_map(filename)

Information about installed software

[lucala]

I had the same issue. The problem is with the python version we're using. As mentioned in this stackoverflow post the MutableSequence is now in collections.abc.

Changing line 23 in your D:\anaconda3\Lib\site-packages\madmom\processors.py file to from collections.abc import MutableSequence solves the issue.

If you're on a mac the path is:

~/anaconda3/lib/python3.11/site-packages/madmom/processors.py

Just add the same change that @lucala provided above
