Question

数百万次尝试后，我尝试在r 3.5.2中安装Lightgbm库。如果有人知道如何安装它？

我尝试了这些方法来安装lightgbm，但总是会发生此类错误。

1。

i.p（...）中的错误：（从警告转换）安装软件包“ C：/Users/MUHAMM~1/AppData/Local/Temp/Rtmp4EX73g/file7d81a401a17/lightgbm_2.2.3.tar.gz”的退出状态为非零另外：警告消息： 1：在untar2（tarfile，文件，列表，exdir）中：跳过pax全局扩展头 2：在untar2（tarfile，文件，列表，exdir）中：跳过pax全局扩展头文件

2。

#1
install.packages('devtools')

install.packages(packageurl, contriburl=NULL, type="source")

#5
lgb.dl(commit = "master", compiler = "vs", # Remove this for MinGW + GPU installation repo = "https://github.com/Microsoft/LightGBM", use_gpu = TRUE)

lgb.dl(commit = "master", compiler = "vs", # Remove this for MinGW + GPU installation repo = "https://github.com/Microsoft/LightGBM",use_gpu = TRUE)

Answer 1

Context mCtx = holder.mView.getContext(); startMyActivity ( mCtx , filterList.get(getAdapterPosition() ).getId() ); // method private void startMyActivity ( Context context , long id ) { Intent intent = new Intent( context , sample_layout.class); intent.putExtra("foods", id ); context.startActivity(intent); }最初是为了简化{lgbl.dl}的安装而创建的，因为{lightgbm}具有难以使用的安装过程。

该软件包没有跟上LightGBM的变化，并且不再需要在Windows上安装R软件包，如此处最初提到的那样。

{lightgbm}现在为on CRAN。运行此R代码进行安装。

{lightgbm}

R 3.5.2中的LightGbm
