在 windows 上安裝帶有 gpu 支持的 lightgbm

Question

我可以從 Windows 提示符的源安裝lightgbm

  A:\LightGBM>Rscript build_r.R 

當我嘗試使用 GPU 支持進行構建時，出現此錯誤：

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")

然后我嘗試在https://github.com/microsoft/LightGBM/tree/master/R-package之后包含 boost 目錄。 我有：

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

我試過有/沒有"/\ 。怎么做？Tks

Answer 1

--boost-include-dir的參數必須是絕對路徑，如下所示：

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