Arch Linux User Repository

Prebuilt binaries of this package and its dependencies can be found in the arch4edu repository.

Please move away from calling setup.py directly and instead use python -m build and python -m installer (together with the appropriate makedepends), as documented in the Arch Linux wiki for python packages:

==> Starting package()...
running install
/usr/lib/python3.12/site-packages/setuptools/_distutils/cmd.py:66: SetuptoolsDeprecationWarning: setup.py install is deprecated.
!!

        ********************************************************************************
        Please avoid running ``setup.py`` directly.
        Instead, use pypa/build, pypa/installer or other
        standards-based tools.

        See https://blog.ganssle.io/articles/2021/10/setup-py-deprecated.html for details.

I get the following warning in build():

writing manifest file 'librosa.egg-info/SOURCES.txt'
/usr/lib/python3.12/site-packages/setuptools/command/build_py.py:207: _Warning: Package 'librosa.util.example_data' is absent from the `packages` configuration.
!!

        ********************************************************************************
        ############################
        # Package would be ignored #
        ############################
        Python recognizes 'librosa.util.example_data' as an importable package[^1],
        but it is absent from setuptools' `packages` configuration.

        This leads to an ambiguous overall configuration. If you want to distribute this
        package, please make sure that 'librosa.util.example_data' is explicitly added
        to the `packages` configuration field.

        Alternatively, you can also rely on setuptools' discovery methods
        (for example by using `find_namespace_packages(...)`/`find_namespace:`
        instead of `find_packages(...)`/`find:`).

        You can read more about "package discovery" on setuptools documentation page:

        - https://setuptools.pypa.io/en/latest/userguide/package_discovery.html

        If you don't want 'librosa.util.example_data' to be distributed and are
        already explicitly excluding 'librosa.util.example_data' via
        `find_namespace_packages(...)/find_namespace` or `find_packages(...)/find`,
        you can try to use `exclude_package_data`, or `include-package-data=False` in
        combination with a more fine grained `package-data` configuration.

        You can read more about "package data files" on setuptools documentation page:

        - https://setuptools.pypa.io/en/latest/userguide/datafiles.html


        [^1]: For Python, any directory (with suitable naming) can be imported,
              even if it does not contain any `.py` files.
              On the other hand, currently there is no concept of package data
              directory, all directories are treated like packages.

@petronny python-lazy-loader and python-soxr are indeed required. The build doesn't fail if the packages are missing, but the module fails at runtime (e.g. if you use librosa.load()—not if you only import librosa!)

@petronny Would you mind adding python-lazy-loader and python-soxr to depends? Those seem to be missing according to namcap.

PSA: python-librosa is currently failing at runtime. This is due to https://bugs.archlinux.org/task/77269.

The error message is:

SystemError: initialization of _internal failed without raising an exception

Once the issue is fixed in python-numba, reinstalling python-numba should fix the issue here as well.

In the meantime, python-numba-git, which already has the patch applied, should work as a drop-in replacement.

@petronny : Version 0.10.0 does build very well, if python-lazy-loader is installed. I suggest to add python-lazy-loader as a makedepends.

Prebuilt binaries of this package and its dependencies can be found in the arch4edu repository.

@zoe Version 0.10.0 could be built in clean chroot. Please check https://github.com/arch4edu/cactus/actions/runs/4232834202/jobs/7353047043

With version 0.10.0, does not build anymore, python-lazy-loader is needed as makedepends :

      ==> Lancement de build()…
      [… … …]
      ModuleNotFoundError: No module named 'lazy_loader'
      ==> ERREUR : Une erreur s’est produite dans build().
          Abandon…
       -> error making: python-librosa

Here's a diff for PKGBUILD (full file) to update the package to the latest release 0.9.1:

• Updated pkgver.
• Used sha256sum check sum.
• Added python-packaging to depends.
• Added --skip-build option to python setup install call in package function.
