一、前言

记录一下如何编译CUDA版本的LightGBM，并在linux服务器上使用，中间遇到一些坑，简单说明一下。

官网的安装教程链接：安装指南 — LightGBM 4.6.0 文档 - LightGBM 框架

二、基础准备

简单交代一下，我使用的是Ubuntu系统，用的是官网的gcc方法来编译安装的。做安装的朋友，建议你把包括英伟达的cuda驱动装好，以免出现意外。另外，像git、vim、wget等这样的基础包，我就不演示安装了，请自行准备。

三、正式安装

1、下载获取github上的LightGBM库

git clone --recursive https://github.com/microsoft/LightGBM

建议使用该方法，而不是自己用电脑在网站上下载后解压，再将解压文件转到服务器上，因为这种下载方法会漏掉文件内容，请看下图：

相当明显，里面是有链接到其他github网页的内容，如果用download按钮去下载，这个文件夹下面就会是空白，后续编译会报错的。当然我会踩这个坑是因为我服务器上网络有点时好时坏：

(my_env) root@yonghu:~/workspace/LightGbm# git clone --recursive https://github.com/microsoft/LightGBM
Cloning into 'LightGBM'...
fatal: unable to access 'https://github.com/microsoft/LightGBM/': Failed to connect to github.com port 443 after 133033 ms: Connection timed out

另外的解决办法就是等服务器自己网络好或者在其他网络好的服务器上用这个命令下载，并传输到要用来做这个工作的服务器上去。

我这里是这样的下载过程：

等下载完成后进入文件夹

cd LightGBM

2、进行编译

再运行下面的命令

cmake -B build -S . -DUSE_CUDA=ON

可能会出现下面的问题：

(my_env) root@950b3d5a9377:~/workspace/LightGbm/LightGBM# cmake -B build -S . -DUSE_CUDA=ON
CMake Error at CMakeLists.txt:27 (cmake_minimum_required):
  CMake 3.28 or higher is required.  You are running version 3.22.1


-- Configuring incomplete, errors occurred!

这个的问题是：

这个错误提示我的 CMake 版本（3.22.1）过低，而 LightGBM 项目要求 CMake 的版本至少为 3.28。

解决方法：

只需要升级CMake即可：
# 1. 下载预编译的 CMake 3.28
cd /tmp
wget https://github.com/Kitware/CMake/releases/download/v3.28.3/cmake-3.28.3-linux-x86_64.sh

# 2. 给执行权限
chmod +x cmake-3.28.3-linux-x86_64.sh

# 3. 安装到 /usr/local（会覆盖旧版本）
./cmake-3.28.3-linux-x86_64.sh --skip-license --prefix=/usr/local

# 4. 验证版本
cmake --version

也可能会出现下面这个问题：

root@yonghu:~/LightGBM# cmake -B build -S . -DUSE_CUDA=ON
-- The C compiler identification is GNU 13.3.0
-- The CXX compiler identification is unknown
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done

CMake Error at CMakeLists.txt:37 (project):
  No CMAKE_CXX_COMPILER could be found.
  Tell CMake where to find the compiler by setting either the environment
  variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path
  to the compiler, or to the compiler name if it is in the PATH.
-- Configuring incomplete, errors occurred!

这个的问题是：

这个错误是因为系统中缺少C++编译器。从错误信息可以看到：

C编译器已找到（GNU 13.3.0）
C++编译器未找到（"The CXX compiler identification is unknown"）

解决方法：

安装C++编译器

首先检查是否安装了g++：
g++ --version
如果没有安装，根据你的Linux发行版安装：
apt-get update
apt-get install g++ build-essential

解决上面的问题以后，正常的运行结果应该是下面这样的：

(my_env) root@yonghu:~/workspace/LightGbm/LightGBM# cmake -B build -S . -DUSE_CUDA=ON
-- The C compiler identification is GNU 11.4.0

然后进行进一步的编译：

cmake --build build -j4

这一步的运行会比较漫长，且可能会出现很多WARNING，但是只要不出现ERROR，就不是什么大问题。比如出现下面的情况：

3、安装python接口

为了方便编程使用，我是使用python来运行的，下面是我安装对应python包的流程：

1、建议使用anaconda的虚拟环境，比如我是my_env，至于怎么创建虚拟环境，就不详述了，属于基础知识。

2、激活环境后在环境内使用这条命令：
sh ./build-python.sh install --precompile
3、通过conda list命令查看是否安装上lightgbm包

4、通过下面的代码可以测试是否成功安装CUDA版本的LightGBM
import lightgbm as lgb

# 检查CUDA支持
try:
    params = {
        'objective': 'binary',
        'device': 'cuda',
        'verbose': -1
    }
    # 创建一个简单数据集进行测试
    import numpy as np
    X = np.random.rand(100, 10)
    y = np.random.randint(0, 2, 100)
    
    model = lgb.train(params, lgb.Dataset(X, label=y), num_boost_round=5)
    print("✓ CUDA 支持已启用!")
except Exception as e:
    print(f"✗ CUDA 支持检查失败: {e}")

四、使用CUDA版本

这个代码会简单对比一下CPU和GPU的速度，在小数据集上CPU会更快一些，只有到了大数据集上才会显现出CUDA的优势。
