python - 在 Windows 10 上安装 numba 和 llvmlite Python 失败

Question

在 Windows 10 失败时安装 numba 和 llvmlite Python

我尝试在 Windows 10 上使用 Python numba 安装

pip 安装 numba

部分成功，但安装 llvmlite 失败

Requirement already satisfied: numpy>=1.15 in c:\users\paul\appdata\local\programs\python\python39\lib\site-packages (from numba) (1.19.2+mkl)

  ERROR: Command errored out with exit status 1:
  
    CMake Error at CMakeLists.txt:9 (find_package):
      Could not find a package configuration file provided by "LLVM" with any of
      the following names:

        LLVMConfig.cmake
        llvm-config.cmake

      Add the installation prefix of "LLVM" to CMAKE_PREFIX_PATH or set
      "LLVM_DIR" to a directory containing one of the above files.  If "LLVM"
      provides a separate development package or SDK, be sure it has been installed.

    -- Configuring incomplete, errors occurred!

不知道 LLVM 安装在哪里？

因此，我使用 Windows 环境编辑器添加值为 C:\Program Files\mingw-w64\winlibs-x86_64-posix-seh-gcc-9.3.0-llvm-10.0.0-mingw-w64-7.0 的 LLVM_DIR。 0-r4\mingw64\lib\cmake\llvm

希望它将使用我安装在 C:\LLVM\clang-1100、C:\LLVM\clang-1000 的四个 Clang 版本之一 ...最新的二进制文件是 C:\LLVM\clang-1100\LLVM\bin

我还安装了 VS 1017 和 1019，所有编译器在其他 IDE 和构建中工作正常。

并下载了最新的wheel

llvmlite-0.34.0-cp39-cp39-win_amd64.whl

并将 LLVM_DIR 添加到系统 PATH

C:\Program Files\mingw-w64\winlibs-x86_64-posix-seh-gcc-9.3.0-llvm-10.0.0-mingw-w64-7.0.0-r4\mingw64\lib\cmake\llvm

这允许它更接近工作，但使用 MSVC 失败

这表明未指定输出文件夹位置，或者 VS 增量构建选项未设置为“未使用”。

或者我应该使用 LLVM 版本，但我不知道如何指定哪个版本，而不是使用 VS2017。

欢迎提出如何走出这个兔子洞的建议 ;-)

谢谢

我想安装 librosa 但我遇到了这个错误，但我设法用这个解决了它:

• 首先我下载最新版本的 llvmlite Here
• 比我运行以下命令:

pip install llvmlite-0.35.0-cp39-cp39-win_amd64.whl

• 接下来，对于 librosa 需要的所有软件包，我按如下方式安装它们:

pip install --no-deps packageName

• 或者只是为了更多示例，请执行以下操作:

pip install librosa --ignore-installed llvmlite
