numpy.distutils.system_info.NotFoundError：未找到 BLAS/LAPACK 库

我在 buildroot 中添加 scikit-learn 包，但它在构建步骤中需要 scipy 依赖项，所以我添加host-python-scipy in python-scipy.mk如下，

HOST_PYTHON_SCIPY_DEPENDENCIES += \
        host-python-numpy \
        host-python-pythran \
        zlib \
        lapack \
        python-numpy \
        python-pybind

then I rebuildscikit-learn，但它给出了另一个错误No BLAS/LAPACK libraries found:

/xxx/buildroot/output/host/lib/python3.10/site-packages/setuptools/config/_apply_pyprojecttoml.py:196: UserWarning: `install_requires` overwritten in `pyproject.toml` (dependencies)

To build Scipy from sources, BLAS & LAPACK libraries need to be installed.

Buildroot有吗MKL图书馆？我怎样才能添加它？

我遵循了答案中的建议，但遇到了另一个问题：

Traceback (most recent call last):

    setup_package()

make: *** [package/pkg-generic.mk:293: /home/xxx/buildroot/output/build/python-scikit-learn-1.1.2/.stamp_built] Error 1

是什么pkg-generic用于？有没有办法在不避免测试执行的情况下解决这个问题？我可以寻求帮助吗？

请检查补丁系列：https://patchwork.ozlabs.org/project/buildroot/list/?series=314036 https://patchwork.ozlabs.org/project/buildroot/list/?series=314036它将 scikit-learn 添加到 Buildroot（但尚未经过审查/合并）。

scikit-learn 和 scipy 的打包相当复杂，因此在执行此操作时遇到麻烦也就不足为奇了。
