#12251 — pyqt5 and entrypoint

Message-ID	<zvulP-6HQ-5@gated-at.bofh.it>

Hello,

We are working on the next pyfai package.

This new version use entry_points like this


 gui_requires = ['PyQt5', 'h5py', 'hdf5plugin', 'PyOpenGL']
    opencl_requires = ['pyopencl']
    extras_require = {
        'calib2': gui_requires,  # Keep compatibility
        'gui': gui_requires,
        'opencl': opencl_requires,
        'full': gui_requires + opencl_requires,
    }

    console_scripts = [
        'check_calib = pyFAI.app.check_calib:main',
        'detector2nexus = pyFAI.app.detector2nexus:main',
        'diff_map = pyFAI.app.diff_map:main',
        'diff_tomo = pyFAI.app.diff_tomo:main',
        'eiger-mask = pyFAI.app.eiger_mask:main',
        'MX-calibrate = pyFAI.app.mx_calibrate:main',
        'pyFAI-average = pyFAI.app.average:main',
        'pyFAI-benchmark = pyFAI.app.benchmark:main',
        'pyFAI-calib = pyFAI.app.calib:main',
        'pyFAI-calib2 = pyFAI.app.calib2:main [gui]',
        'pyFAI-drawmask = pyFAI.app.drawmask:main',
        'pyFAI-diffmap = pyFAI.app.diff_map:main',
        'pyFAI-integrate = pyFAI.app.integrate:main',
        'pyFAI-recalib = pyFAI.app.recalib:main',
        'pyFAI-saxs = pyFAI.app.saxs:main',
        'pyFAI-waxs = pyFAI.app.waxs:main',
    ]

    entry_points = {
        'console_scripts': console_scripts,
        # 'gui_scripts': [],
    }



But once installed, we can not start the gui application.


jerome@patagonia:~/workspace/hdf5plugin$ pyFAI-calib2

    raise DistributionNotFound(req, requirers)
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 Debian.

thanks for your help

Frederic

Please make sure you have python3-pyqt5 ≥ 5.12+dfsg-1.

If that is the case and you are still getting an error, please check
the output of the following commands in the Python console:

>>> import pkg_resources
>>> pkg_resources.get_distribution('PyQt5')

For me it prints “PyQt5 5.14.1 (/usr/lib/python3/dist-packages)”.

Since you know that the dependency is satisfied due to your package dependencies in debian/control, you should be able to patch away the requires PyQt5 in setup.py and it'll work fine.
