Ewoks install for .ows files

@woutdenolf

Original workflow a user would download: test.ows

ewoks convert test.ows conv.ows
ewoks convert test.ows conv.json

conv.json

conv.ows

This does not work because ewoksfluo was an editable install?

pip install ewoks[orange]
ewoks install conv.json
ewoks execute conv.json

ModuleNotFoundError: No module named 'ewoksfluo'
FAILED

OWS files do not retain the requirements

pip install ewoks[orange]
ewoks install conv.ows

This will run f`/users/denolf/.local/wdnbashutils/virtualenvs/pybox_ELoM5Y/bin/python -m pip install `. Do you want to proceed (y/N)?

Do I read correctly that there are actually two issues here ?

That this snippet do not work:

pip install ewoks[orange]
ewoks install conv.json
ewoks execute conv.json

ModuleNotFoundError: No module named 'ewoksfluo'
FAILED

And that ewoks install does not work for ows ?

For the first, I actually couldn't execute ewoks install for two reasons:

blissdata points to a local folder via subdirectory
Packages require conflicting versions of docutils:

The conflict is caused by:
    The user requested docutils==0.20.1
    chios 1.0.0 depends on docutils
    nbsphinx 0.9.5 depends on docutils>=0.18.1
    orange-canvas-core 0.2.2 depends on docutils
    pydata-sphinx-theme 0.15.4 depends on docutils!=0.17.0
    readme-renderer 44.0 depends on docutils>=0.21.2

Editable installs do not raise an issue in general since they are translated to a git+ dependency with the commit hash which is quite neat.

To clarify: graph attributes are not stored in .ows which means we need to extract it from the tasks which means we need to convert the orange widgets to the tasks which means we already need to have the package installed.

@loichuder

@loichuder @woutdenolf what is the status of this? I am not sure it's relevant anymore since it was from 2024.

This already fails before I can reproduce the problem:

pip install --pre ewoksfluo pyqt5 ewoks

ewoks convert map_1det.ows test.ows -o root_module=orangecontrib.ewoksfluo.categories.demo.tutorials

This also fails:

The raise RuntimeError("ewoksdemo is disabled") was already reported by @abmajith . Could you take care of that one? Ticket ewoks-kit/ewoksorange#488

So I failed to even arrive at reproducing the issue but I think ewoks-kit/ewoksorange#419 + ewoks-kit/ewoksorange#422 solve the original problem with ewoks install of a .ows file.

Edit: the problem is partially solved

ewoks-canvas                       # saving the worklfow from the UI does not save the graph attributes
ewoks convert test.ows tmp.ows     # this adds the graph attributes
ewoks install tmp.ows              # this allows installing the .ows file

So I close this ticket (.ows files can be installed) and the rest goes to other tickets:
