What's wrong?
Installing using pip3 install orange3 throws the following error:

Collecting orange3

How can we reproduce the problem?
Installing orange using pip3 install orange3 command on a Linux system with Python version 3.12.1 installed.

What's your environment?

• Operating system: Fedora 39
• Orange version: 3.36.2
• How you installed Orange: pip3 install orange3

Orange version 3.36.2 does not appear to be compatible with Python 3.12. This particular issue seems to be fixed in the master branch as of 2b1558a

There seems to be another issue. A dependency, namely catboost, does not have packages for 3.12 yet. This might or might not be a problem for you (maybe it can be built by pip dynamically) even if you build from the master branch.
