在R中安装lightgbm [英] Installing lightgbm in R

问题描述

我尝试了其他方法来安装lightgbm软件包，但无法完成.我在 github存储库中尝试了所有方法，但是它们不起作用. 我运行Windows 10和R 3.5(64位).有有人也有类似的问题.所以我尝试了他的解决方案:

I have tried different things to install the lightgbm package but I can´t get it done. I tried all methods at the github repository but they don't work. I run Windows 10 and R 3.5 (64 bit). There is someone with similar problems. So I tried his solution:

1. 安装cmake(64位)

1. 安装Visual Studio(2017)

1. 安装Rtools(64位)

1. 将系统变量中的路径更改为"C:\ Program" Files \ CMake \ bin \ cmake;"

1. Changing Path in the System Variables to "C:\Program Files\CMake\bin\cmake;"

1. 使用预编译的dll/lib安装lightgbm

->

  devtools::install_github("Laurae2/lgbdl", force = TRUE)
  library(lgbdl)
  lgb.dl(commit = "master",
  compiler = "vs",
  repo = "https://github.com/Microsoft/LightGBM")

 *** arch - i386
installing via 'install.libs.R' to C:/Users/X1/Documents/R/win- 
library/3.5/lightgbm
Error in eval(ei, envir) : Cannot find lib_lightgbm.dll
* removing 'C:/Users/XXX/Documents/R/win-library/3.5/lightgbm'
In R CMD INSTALL
installation of package 
�C:/Users/XXX/AppData/Local/Temp/RtmpczNLaN/LightGBM/R-package� had non- 
zero exit status[1] FALSE

有什么办法解决这个问题吗?

Any idea how to fix this?

推荐答案

它对我有用，希望对您有所帮助.

It works for me, hope it helps.

1. 确保您安装了所有必需软件

1. Make sure you install all mandatory software

从 https://github.com/Microsoft/LightGBM下载预编译的.dll文件/版本 并将其放入.\ LightGBM \

Download the precomplied .dll file from https://github.com/Microsoft/LightGBM/releases and put it in .\LightGBM\

在install.libs.R中，设置use_precompile<-TRUE

In install.libs.R, set use_precompile <- TRUE

将CMakeLists.txt从根目录复制到.\ LightGBM \ R-package \ inst \ bin

Copy CMakeLists.txt from root directory into .\LightGBM\R-package\inst\bin

在R控制台中，输入: install.packages(file.path("C:\ yourdirectory \"，"LightGBM"，"R-package")，repos = NULL，类型="source")

In R console type: install.packages(file.path("C:\yourdirectory\", "LightGBM", "R-package"), repos = NULL, type = "source")
