python - Python 的 Lightgbm GPU 安装

Question

第一次尝试-) 我安装了 CMake、Mingw、Boost 并且已经有了 VS 2017 社区版本。我使用this成功安装了它指导。我什至在 Git Bash 上测试过它并且它有效。但我想这不适用于Python？因为我无法在 Python IDLE、Notebook 等上导入和使用它。

第二次尝试-)另外，我使用this通过VS安装了它。指导。它说.exe 文件将位于 LightGBM-master/windows/x64/Release 文件夹中。 我想这个指南是为 VS 用户准备的，而不是为我准备的？

第三次尝试-) pip install lightgbm --install-option=--gpu给我错误:异常:请先安装 CMake我已经有了 CMake，并将 CMake 添加到系统和用户路径中。

C:\Program Files\CMake\bin

还给出有关 Boost 变量的警告，但在第一次尝试中，我能够使用 Boost 安装 lightgbm。

LightGBM_compilation.txt 更详细地显示错误:

Answer 1

问题是我从本指南中获得了 boost 文件，但它不是我想要的 python 安装。 https://lightgbm.readthedocs.io/en/latest/GPU-Windows.html

那个 boost 文件没有这个库/lib64-msvc-14.1我安装了boost_1_69_0-msvc-14.1-64.exe，这是我从here获得的.

我添加了 boost 参数并且它起作用了!

pip install lightgbm --install-option=--gpu --install-option="--boost-root=C:/local/boost_1_69_0" --install-option="--boost-librarydir=C:/local/boost_1_69_0/lib64-msvc-14.1"

每次尝试 pip install 时，我都会遇到以下异常。如果有人遇到同样的问题，我希望这个解决方案对他们有用。
