[Debian-pan-maintainers] SOLEIL debian packaging status: pyimagetool and freeart/tomogui

[Emmanuel FARHI]

Hi Roland,

some progress around pyimagetool. It is not intended to be used as an 
application, but only as a widget or through a jupyter notebook.

However, it requires some files to be writable, which is wierd.

A solution to identify the issue is to brute force:

  * sudo chmod -R a+rwx /usr/lib/python3/dist-packages/pyimagetool

Then one can launch for instance

  * jupyter-notebook /usr/share/pyimagetool/examples/ExampleNotebook.ipynb

which fully works on bullseye.


But is now broken on bookworm, as pyqt6 has changed some of its API.

File/usr/lib/python3/dist-packages/pyimagetool/PGImageTool.py:24, inPGImageTool()
22  index_to_coord: List[str]=  ['x','y','z','t']
23  frame_rate=  60
---> 24  bin_pen=  pg.mkPen(style=pg.Qt.QtCore.Qt.DashLine)
26  mouse_hover=  QtCore.Signal(str)# event fired when the mouse moves on an image
28  def  __init__(self, data: RegularDataArray, parent=None, layout=0):

AttributeError: type object 'Qt' has no attribute 'DashLine'

I pushed an issue on the relevant github project:

  * https://github.com/kgord831/PyImageTool/issues/5

So my conclusion is that this is deprecated, and not maintained anymore 
(last commit dates from Jan 2021).
An adaption to current QT6 would be needed. The only solution, as it 
works for bullseye, is to save the package into bullseye-backport.

For freeart/tomogui, this is the same, the package is not anymore 
adapted to Debian libraries and not maintained. It does not even build.

Let's send bug reports to debian lists, and let them be kicked-out.

Emmanuel.
