Python 3.14 support for pymoo

[debpal]

Problem

When attempting to install pymoo in a Python 3.14 environment, the installation fails with multiple build errors.
This suggests that the current release of pymoo does not yet support Python 3.14.

Proposed Solution

Please update the build configuration and dependencies to make pymoo compatible with Python 3.14.

We are developing a package, pySWATPlus, which depends on pymoo, and Python 3.14 compatibility would be essential for continued integration and testing.

Will be addressed by:

• python 3.14 and aarch64 linux wheels #758

Note that this just enables building wheels for python 3.14, which will be distributed on pypi. No code changes were required, so my impression is that pymoo is already compatible with python 3.14.

Can you please indicate your environment, steps you use to build, and the errors you run into please?

e.g. try something like this -- for me this works:

$ uv run --isolated --no-project --with pymoo==0.6.1.5 --no-binary-package pymoo --python 314 python -c "import pymoo.util.function_loader; print(pymoo.util.function_loader.is_compiled())"
True

@tpgillam Thank you for your response.

I’m not very experienced with software development. When I ran pip install pymoo in a Python 3.14.0 environment, the installation failed with many errors — mostly related to cpython and cython.

Up to Python 3.13.9, pymoo installs and works correctly.
Below are the error logs I received during installation.

          Python recognizes 'pymoo.cython' as an importable package[^1],
          but it is absent from setuptools' `packages` configuration.

          This leads to an ambiguous overall configuration. If you want to distribute this
          package, please make sure that 'pymoo.cython' is explicitly added
          to the `packages` configuration field.

          Alternatively, you can also rely on setuptools' discovery methods
          (for example by using `find_namespace_packages(...)`/`find_namespace:`
          instead of `find_packages(...)`/`find:`).

          You can read more about "package discovery" on setuptools documentation page:

          - https://setuptools.pypa.io/en/latest/userguide/package_discovery.html

          If you don't want 'pymoo.cython' to be distributed and are
          already explicitly excluding 'pymoo.cython' via
          `find_namespace_packages(...)/find_namespace` or `find_packages(...)/find`,
          you can try to use `exclude_package_data`, or `include-package-data=False` in
          combination with a more fine grained `package-data` configuration.

Ah ok, yep you'll need a working C++ compiler on your system to build from scratch (hence the error about not having Visual c++ installed).

Once we release the new wheels this should be resolved.

@tpgillam

Most of the code in: https://github.com/anyoptimization/pymoo/tree/main/pymoo/functions/compiled
is already implemented in moocore or would be welcome in moocore, which is already a dependency of pymoo.

moocore already provides wheels for aarch64/arm64 on linux, windows and macos: https://github.com/multi-objective/moocore/tree/main/python#install

Getting rid of compiled code in pymoo and relying on moocore for that would probably help both developers and users of pymoo.

Thanks for the thought @MLopez-Ibanez - I leave that decision to @blankjul (I'm just helping with pymoo's wheel building from time to time).

Python 3.14 support will be available once @blankjul has a chance to review #758 and make a new release.

[blankjul]

I just merged the PR!

[MLopez-Ibanez]

@debpal

Are you trying to use Python 3.14 or Python 3.14t (free-threading version: https://docs.python.org/3/howto/free-threading-python.html) ?

[blankjul]

The new version supports now Python 3.14.

We are currently not planning to support the free threaded version (flagged as experimental).
