Poetry build broken during numpy install

[jmachuca77]

ubuntu 22.04
python version 3.12.8

The current version fails during the 'poetry install' command with the following error:

  - Installing jupyter-lsp (2.2.0)
  - Installing jupyterlab-server (2.24.0)
  - Installing notebook-shim (0.2.3)
  - Installing numpy (1.25.2): Failed

PEP517 build of a dependency failed

Backend 'setuptools.build_meta:__legacy__' is not available.

Note: This error originates from the build backend, and is likely not a problem with poetry but one of the following issues with numpy (1.25.2)

  - not supporting PEP 517 builds
  - not specifying PEP 517 build requirements correctly
  - the build requirements are incompatible with your operating system or Python version
  - the build requirements are missing system dependencies (eg: compilers, libraries, headers).

You can verify this by running pip wheel --no-cache-dir --use-pep517 "numpy (==1.25.2)".

Thank you for sharing the issue.
I found a related case here saying that python 3.12 and numpy 1.25 cannot coexist.

Can you try the followings?

• clone the repository
• open pyproject.toml with a text editer and change numpy version from "1.25.2" to "1.26.4" in the line.
  • https://github.com/MizuhoAOKI/python_simple_mppi/blob/master/pyproject.toml#L11
• run poetry install
