Support for python 3.13

Feature Description

Hey people, I see there is a hard requirement for python < 3.13, and I wonder if there have been any efforts to allow for python 3.13 too.

Problem or Use Case

No response

Proposed Solution

Allowing for python 3.13 would be nice :)

Alternatives Considered

No response

Additional Context

I did try to do the upgrade locally. The steps I followed were to:

• Edit pyproject.toml and remove the <3.13 requirement
• Create a 3.13 env with uv
• Run uv pip install -e ".[server,dev]" as per the CONTRIBUTING.md file
• Then I tried to run the tests with bash scripts/test-coverage-xml.sh

At this point the issues started. The first one was:

ERROR: usage: __main__.py [options] [file_or_dir] [file_or_dir] [...]
__main__.py: error: argument --splitting-algorithm: invalid choice: 'least_duration' (choose from )

I looked for the --splitting-algorithm flag in the bash script and removed it, which allowed the tests to run, but then I hit a second issue:

numpy and bs4 where not installed...
After manually installing these two, the tests started running but failed with an error in numpy.

All of this tells me that there is probably something wrong with my set up that might not be related to python 3.13 at all.

Hey @SpyrosRoum, thank you for opening the issue. Before we can officially start supporting 3.13, it needs to be tested quite throughly. This includes not just the changes to the pyproject.toml but also to our testing suite and codebase. I will report this to the team and we will look into it.

If you want to run the tests locally, you can run bash scripts/install-zenml-dev.sh --integrations yes.

I figured as much, but I hoped that being able to report that at least tests pass would be a good first step towards that :)

If you want to run the tests locally, you can run bash scripts/install-zenml-dev.sh --integrations yes.

I started with a clean env and used this command to install dependencies now.

I still had to remove the --splitting-algorithm least_duration flag. numpy was installed this time but bs4 was missing, but it looks like it's not a hard dependency because tests did start.

They still didn't get far at all though, failing, with the end of the stack trace being

INTERNALERROR>   File "/Users/spyros/.local/share/uv/python/cpython-3.13.7-macos-aarch64-none/lib/python3.13/enum.py", line 793, in __getitem__
INTERNALERROR>     return cls._member_map_[name]
INTERNALERROR>            ~~~~~~~~~~~~~~~~^^^^^^
INTERNALERROR> KeyError: 'duration_based_chunks'

In any case, I understand this is not a priority but I would appreciate it if you can look into it eventually. Thank you :)
