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)”.

pyqt5 and entrypoint

[PICCA Frederic-Emmanuel]

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.

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
