Question

我可以通过 Windows 提示从源代码安装 lightgbm

  A:\LightGBM>Rscript build_r.R

当我尝试使用 GPU 支持进行构建时，出现此错误：

CMake Error at A:/programas/CMake/share/cmake-3.19/Modules/FindPackageHandleStandardArgs.cmake:218 (message):
-- Configuring incomplete, errors occurred!
  Could NOT find Boost (missing: Boost_INCLUDE_DIR filesystem system)
  (Required is at least version "1.56.0")

然后我尝试在 https://github.com/microsoft/LightGBM/tree/master/R-package 之后包含 boost 目录。我得到：

A:\LightGBM>Rscript build_r.R --use-gpu --boost-include-dir="/programas/boost_1_75_0/"
...
...
installing via 'install.libs.R' to A:/RLibrary/00LOCK-lightgbm/00new/lightgbm
Error in eval(ei, envir) : objeto 'programas' não encontrado

我试过有/没有"/\。怎么做？ tks

Answer 1

--boost-include-dir 的参数需要是绝对路径，如下所示：

Rscript build_r.R --use-gpu --boost-include-dir="A:/programas/boost_1_75_0/"

在 Windows 上安装支持 gpu 的 lightgbm
