Question

我尝试在Windows 7的R中安装具有GPU支持的XGBoost。我按照此处的安装指南（http://xgboost.readthedocs.io/en/latest/build.html#installing-r-package-with-gpu-support）进行操作，直到最后一步都很好。我花了几天的时间搜索，找不到解决方案。有人可以帮我吗？

这是我在Git Bash中遵循的过程：

git clone --recursive https://github.com/dmlc/xgboost
cd xgboost
git submodule init
git submodule update
mkdir build
cd build
cmake .. -G"Visual Studio 14 2015 Win64" -DUSE_CUDA=ON -DR_LIB=ON -DLIBR_EXECUTABLE="C:/Program Files/R/R-3.4.1/bin/x64/R.exe"
cmake --build . --target install --config Release

在最后一步找到以下错误

"C:\Users\geng\xgboost\build\install.vcxproj" (default target) (1) ->
(PostBuildEvent target) ->

如果我改为执行此命令（cmake --build . --target xgboost --config Release），则没有错误。但是，我不知道从这里应该怎么做。如果我只是做这样的事情：

cd R-package
"C:/Program Files/R/R-3.4.2/bin/R.exe" CMD INSTALL .

它以另一个不同的错误结尾，如下所示。我不知道我做错了什么，非常感谢您的帮助。提前非常感谢您！

Answer 1

没关系，我找出了原因。这与我的Rtools设置有关。我重新安装它，并确保PATH包含以下两项，然后问题已解决。

c：\ Rtools \ bin; c：\ Rtools \ mingw_64 \ bin

无法在Windows 7上安装具有GPU支持的R XGBoost
