lightgbm(gpu)在linux(centos7)安裝

#保證gpu是正常可用的：
nvidia-smi
nvcc -V

#進入root權限，且python環境爲你正常使用環境，比如anaconda3，而不是python2.7
#依賴：sudo apt-get install --no-install-recommends git cmake build-essential libboost-dev libboost-system-dev libboost-filesystem-dev

#首先進行必要的升級：
#cmake>=3.2(eg: v3.16.8)
#https://cmake.org/download/
./configure
make
make install
cmake -version #若不正常顯示，則添加軟連接：
ln -s /xxx/cmake /usr/bin/cmake

#boost>=1.56(eg: v1.61)
#https://dl.bintray.com/boostorg/release/
#安裝會有一些錯誤，但沒關係～～～之前浪費很多時間
./bootstrap.sh --with-python=/xxx/anaconda3/bin/python --with-python-version=3.x --with-python-root=/xxx/anaconda3/bin/python3.x
./b2
./b2 install

#lightgbm==2.3.2
git clone --recursive https://github.com/microsoft/LightGBM
cd LightGBM
mkdir build ; cd build
cmake -DUSE_GPU=1 -DOpenCL_LIBRARY=/usr/local/cuda/lib64/libOpenCL.so -DOpenCL_INCLUDE_DIR=/usr/local/cuda/include/ ..
make -j$(nproc)
python ../python-package/setup.py install #注意你要安裝到哪個python環境下

#To test！
