Summary of Docker build error:

- Exact error message and exit code
  - E: Package 'cython' has no installation candidate
  - Package cython is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source
  - Exit code: 100

- Failing command/step

- Missing packages or files mentioned
  - cython (missing: no installation candidate)

- Version mismatch information
  - Base image is Ubuntu 22.04 (jammy); there is no explicit version mismatch reported. The failure stems from the cython package not being available in the jammy repositories at install time.

  - Preparing metadata (pyproject.toml): started
  - Preparing metadata (pyproject.toml): finished with status 'error'
  - error: subprocess-exited-with-error
  - × Preparing metadata (pyproject.toml) did not run successfully.
  - exit code: 1
  - ../meson.build:196:2: ERROR: Problem encountered: Missing the `array_api_compat` submodule! Run `git submodule update --init` to fix this.
  - A full log can be found at /workspace/scipy/.mesonpy-azx5z3r9/meson-logs/meson-log.txt
  - note: This error originates from a subprocess, and is likely not a problem with pip.
  - metadata-generation-failed
  - × Encountered error while generating package metadata.
  - × from file:///workspace/scipy
- Missing packages or files mentioned:
  - Missing submodule: array_api_compat (as indicated by “Missing the `array_api_compat` submodule! Run `git submodule update --init` to fix this.”)
- Version info mentioned:
  - Meson build system version: 1.10.2 (visible in the logs)
  - Python: 3.12 (runtime, from host: YES 3.12)
  - SciPy project version in log: 1.18.0.dev0+git20260320.9bf351b

Note: The build fails due to the missing array_api_compat submodule, not due to a Python package build issue.

- Missing packages or files mentioned:
  - ninja
  - cython
  - pybind11

- Version mismatch / environment context:
  - Base image used: python:3.11-slim-bullseye
  - Debian bullseye package sources appear to lack ninja, cython, and pybind11 in this setup, causing installation failures. This is not a successful download or a file/mismatch in the Dockerfile itself, but an availability issue in the distros' apt repositories for this target.

- Notes:
  - The error stems from package availability rather than command syntax. Potential fixes include using alternative package names (e.g., ninja-build, cython3, python3-pybind11), enabling different repos or backports, or switching to a newer Debian variant (e.g., bookworm) where these packages are available.

      File "/app/scipy/__init__.py", line 53, in <module>
        raise ImportError(msg) from e

Context and missing/files/versions
- The failure occurs because SciPy is being imported from its source directory ( /app/scipy ), which SciPy blocks with an ImportError.
- Python version: 3.11 (from base image)
- Installed/tested library versions observed around this step:
  - numpy 2.4.3
  - scipy 1.17.1
  - SciPy import fails despite the above being installed, due to SciPy source-directory import restriction.

Notes
- The build attempted a smoke test after installing numpy and scipy; the test failed during import, not due to a missing package file on the Debian side. The root cause is importing SciPy from the SciPy source directory rather than an installed package.

- Exit code: 1

- Exact error messages observed:
  ERROR: Ignored the following versions that require a different python version: 2.3.0 Requires-Python >=3.11; 2.3.1 Requires-Python >=3.11; 2.3.2 Requires-Python >=3.11; 2.3.3 Requires-Python >=3.11; 2.3.4 Requires-Python >=3.11; 2.3.5 Requires-Python >=3.11; 2.4.0 Requires-Python >=3.11; 2.4.0rc1 Requires-Python >=3.11; 2.4.1 Requires-Python >=3.11; 2.4.2 Requires-Python >=3.11; 2.4.3 Requires-Python >=3.11
  ERROR: Could not find a version that satisfies the requirement mesonpy (from versions: none)
  ERROR: No matching distribution found for mesonpy

- Context that helped diagnose the issue:
  - Base image context shows Python 3.10 (python:3.10-slim-bullseye) being used for the build.
  - The error explicitly states that mesonpy requires Python >= 3.11, which is incompatible with Python 3.10 in the current build environment.

- Missing/miscompatible package/files mentioned:
  - mesonpy cannot be installed due to Python version constraints (no matching distribution for mesonpy).

- Version mismatch info:
  - Mesonpy versions available require Python 3.11+ (as shown by the “Requires-Python >=3.11” note), while the build uses Python 3.10 in the base image. This is the root cause of the failure.

  ModuleNotFoundError: No module named 'scipy.__config__'

  The above exception was the direct cause of the following exception:

  ImportError: Error importing SciPy: you cannot import SciPy while
      being in scipy source directory; please exit the SciPy source
      tree first and relaunch your Python interpreter.

- Missing packages or files mentioned:
  - ModuleNotFoundError: No module named 'scipy.__config__' (occurs during SciPy import)

- Version mismatch / installed versions:
  - numpy 2.4.3
  - scipy 1.17.1
  - Python base image: python:3.11-slim-bullseye
  - The error arises after SciPy was installed from wheels (numpy-2.4.3, scipy-1.17.1)

- Additional context:
  - The error indicates SciPy is being imported from the SciPy source directory at /workspace/scipy, which is not allowed; this shadows the installed SciPy and triggers the import failure.

- Failing command/step
  - Dockerfile step: RUN python -m pip wheel . -w /wheels (builder 7/7)

- Missing packages or files mentioned
  - Not missing packages/files; the failure is due to a Python version mismatch. The build expects Python 3.12+; the environment provides Python 3.10 (as shown by "Minimum supported Python version is 3.12, found 3.10" and host Python). No filesystem/missing-package error is reported beyond the version requirement.

- Version mismatch info
  - Base image uses Python 3.10: python:3.10-slim-bullseye
  - Build requires Python >= 3.12 (Meson build error)
  - Meson version visible in log: 1.10.2
  - Project metadata shows SciPy 1.18.0.dev0
  - Python runtime used during wheel-building: /usr/local/bin/python (3.10.x)

Notes:
- To fix, upgrade the base image to Python 3.12+ (or adjust dependencies to be compatible with 3.10).
- The error originates from the Meson build step invoked during wheel generation, not from a pip/-wheel packaging error alone.

Summary (under 1500 chars):

- Failing command/step:
  - Builder step [builder 7/7] RUN python -m pip wheel . -w /wheels

- Exact error message and exit code:
  - The Meson build system
    ../meson.build:29:2: ERROR: Problem encountered: Minimum supported Python version is 3.12, found 3.11
  - Exit code: 1

- Missing packages or files mentioned:
  - None reported. The failure is due to a Python version mismatch, not missing dependencies.

- Version mismatch/info:
  - Base image uses Python 3.11 (python:3.11-slim-bookworm)
  - Meson build requires Python >= 3.12 (minimum 3.12)
  - Project context shows SciPy version: 1.18.0.dev0+git20260320.9bf351b

- Context note:
  - The wheel-building step fails during metadata generation because the project’s Meson build enforces Python 3.12+, incompatible with the 3.11 base image. Consider upgrading the Python base to 3.12+ or adjusting the build to target a compatible Python version.

Summary of Docker build error

- Exact error message and exit code
  - Exit code: 1
  - The build failed during the wheel generation step with:
    - "ERROR: process \"/bin/sh -c python -m pip wheel . -w /wheels\" did not complete successfully: exit code: 1"
  - Meson-based metadata generation failed with:
    - "Preparing metadata (pyproject.toml): finished with status 'error'"
    - "The Meson build system ... PROJECT NAME: scipy ... PROJECT VERSION: 1.18.0.dev0"
    - "The Meson build system ... ../meson.build:196:2: ERROR: Problem encountered: Missing the `array_api_compat` submodule! Run `git submodule update --init` to fix this."

- Failing command/step
  - RUN python -m pip wheel . -w /wheels (Dockerfile line: RUN python -m pip wheel . -w /wheels)

- Missing packages or files mentioned
  - Missing the array_api_compat submodule required by the SciPy build:
    - "ERROR: Problem encountered: Missing the `array_api_compat` submodule! Run `git submodule update --init` to fix this."

- Version mismatch info (present in logs)
  - Base image: python:3.12-slim-bookworm
  - SciPy project version: 1.18.0.dev0
  - Meson version: 1.10.2
  - Host toolchain (from log): GCC 12.2.0, GFortran 12.2.0
  - Runtime Python: 3.12

Notes
- The root cause is a missing git submodule (array_api_compat); initializing submodules should fix the build, e.g., git submodule update --init.

- Exact error messages and exit code to preserve:
  - subprocess-exited-with-error
  - Preparing metadata (pyproject.toml) did not run successfully.
  - exit code: 1
  - metadata-generation-failed
  - ../meson.build:29:2: ERROR: Problem encountered: Minimum supported Python version is 3.12, found 3.10

- Why it failed (version mismatch info):
  - The build uses Python 3.10 (FROM python:3.10-slim-bullseye; Run-time dependency python found: YES 3.10).
  - Meson reports minimum required Python version is 3.12, so Python 3.10 is not supported for this build of SciPy (Project version: 1.18.0.dev0).

- Missing packages or files mentioned:
  - None explicitly mentioned as missing. The failure is due to a Python version mismatch (no file/package missing noted in the error).

- Context notes:
  - The error occurs during wheel generation for the SciPy project from source, not due to a missing package. The Meson log points to a Python version requirement (3.12+) that is not met by the base image’s Python.
