python llvmlite 安装iisue - 未检测到 SVML

Question

尝试制作一个以 numba 0.33.0 作为依赖项的 python 脚本在 ubuntu 14.0.4 上工作。已安装 llvm 6.0 并将 llvm_config 变量设置为 llvm_config 位置。

构建 llvmlite 时遇到的问题

以下是堆栈跟踪

Answer 1

请检查您的

LLVM_CONFIG

环境变量，如此处所述。

如果您的 LLVM 安装在非标准位置，请设置 LLVM_CONFIG环境变量对应的位置 llvm-config 或 llvm-config.exe 可执行文件。该变量必须持续存在 进入 llvmlite 的安装 — 例如，进入 Python 环境。

示例：如果 LLVM 使用 llvm-config 安装在 /opt/llvm/ 中 二进制文件位于 /opt/llvm/bin/llvm-config，设置 LLVM_CONFIG=/opt/llvm/bin/llvm-config。

Answer 2

与

numba -s

我发现python 3.11 numba 0.57.0

    __SVML Information__
    SVML State, config.USING_SVML                 : False
    SVML Library Loaded                           : True
    llvmlite Using SVML Patched LLVM              : False
    SVML Operational                              : False

我安装了

    +intel/win-64::icc_rt-2023.1.0-intel_46319
    +conda-forge/win-64::llvmlite-0.40.1-py311h5bc0dda_0

安装后

conda install -c numba llvmlite

llvmlite 新版本现已推出

llvmlite Version : 0.40.1+0.ga4e5632.dirty

和

numba -s

立即报告：

    __SVML Information__
    SVML State, config.USING_SVML                 : True
