Can't run ppo_pettingzoo_ma_atari.py

[KevayneCst]

After cloning and creating venv using uv venv, source .venv/bin/activate, and finally uv pip install -r pyproject.toml --all-extras, (in order to get the optional dependencies like supersuit, that is needed for ma_atari)

I get the following error:

      /XX/.cache/uv/builds-v0/.tmpwFjuZp/lib/python3.10/site-packages/setuptools/command/build_py.py:212: _Warning: Package 'multi_agent_ale_py.tests.fixtures' is absent
      from the `packages` configuration.
      !!

              ********************************************************************************
              ############################
              # Package would be ignored #
              ############################
              Python recognizes 'multi_agent_ale_py.tests.fixtures' 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 'multi_agent_ale_py.tests.fixtures' 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 'multi_agent_ale_py.tests.fixtures' to be distributed and are
              already explicitly excluding 'multi_agent_ale_py.tests.fixtures' 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.

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

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


              [^1]: For Python, any directory (with suitable naming) can be imported,
                    even if it does not contain any `.py` files.
                    On the other hand, currently there is no concept of package data
                    directory, all directories are treated like packages.

Please note that when following the commands here, I get the same error message.

Do you have any idea ? #408 ? Thanks.
