Hello,

We are working on the next pyfai package.

This new version use entry_points like this


 gui_requires =3D ['PyQt5', 'h5py', 'hdf5plugin', 'PyOpenGL']
    opencl_requires =3D ['pyopencl']
    extras_require =3D {
        'calib2': gui_requires,  # Keep compatibility
        'gui': gui_requires,
        'opencl': opencl_requires,
        'full': gui_requires + opencl_requires,
    }

    console_scripts =3D [
        'check_calib =3D pyFAI.app.check_calib:main',
        'detector2nexus =3D pyFAI.app.detector2nexus:main',
        'diff_map =3D pyFAI.app.diff_map:main',
        'diff_tomo =3D pyFAI.app.diff_tomo:main',
        'eiger-mask =3D pyFAI.app.eiger_mask:main',
        'MX-calibrate =3D pyFAI.app.mx_calibrate:main',
        'pyFAI-average =3D pyFAI.app.average:main',
        'pyFAI-benchmark =3D pyFAI.app.benchmark:main',
        'pyFAI-calib =3D pyFAI.app.calib:main',
        'pyFAI-calib2 =3D pyFAI.app.calib2:main [gui]',
        'pyFAI-drawmask =3D pyFAI.app.drawmask:main',
        'pyFAI-diffmap =3D pyFAI.app.diff_map:main',
        'pyFAI-integrate =3D pyFAI.app.integrate:main',
        'pyFAI-recalib =3D pyFAI.app.recalib:main',
        'pyFAI-saxs =3D pyFAI.app.saxs:main',
        'pyFAI-waxs =3D pyFAI.app.waxs:main',
    ]

    entry_points =3D {
        'console_scripts': console_scripts,
        # 'gui_scripts': [],
    }



But once installed, we can not start the gui application.

pkg_resources.DistributionNotFound: The 'PyQt5' distribution was not
found and is required by the application


indeed python3-pyqt5 was installed

so Is it a bug in the pyqt5 package, or is there a way to fix this in Debia=
n.

thanks for your help
