Install error on Fedora 36

[Barugon]

Trying to install this on Fedora 36 and ran into a few snags in the pip install -r requirements.txt portion. I was able to resolve them (missing dependencies) up until this one:

OK, I got through this by changing from collections import ... to from collections.abc import ... in various places in ./displaycal_venv/lib64/python3.10/site-packages/attrdict.

Got it installed and now I get this:

[Barugon]

The current version of wxGTK3 in Fedora 36 is 3.0.5.

[p5k369]

OK, I got through this by changing from collections import ... to from collections.abc import ... in various places in ./displaycal_venv/lib64/python3.10/site-packages/attrdict.

Hey @Barugon you should not need to change anything here. This is a third party module which should work fine with wxpython-4.2.0.

I guess this comes from a not working wxPython install. You can try several things:

• Maybe this can be resolved very simple by removing wxPython with pip and reinstalling it
• This might be not enough and if you cant track down all your modifications you might need a new virtual environment
• If you cant get it running and it is related to attrdict3 and wxpython-4.2.0 restrict wxpython version to wxPython==4.1.1 in requirements file. You will lose no functionality.

Tell us if you cant get it resolved, cheers.

edit:
forgot to mention: reinstall with --no-cache-dir

[eoyilmaz]

Hey @Barugon yeah I was going to say the things @p5k369 already mentioned, we should probably stick with wxPython 4.1.1 for a while.

[eoyilmaz]

Clsoing this as this is fixed somewhere along the line...
