xgboost安装

1.安装Homebrew
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2.安装最新版本gcc
brew install gcc --without-multilib

安装最新版的gcc,安装好以后确认是gcc7,g++7

git clone --recursive https://github.com/dmlc/xgboost

3. 编译xgboost
   cd xgboost; cp make/config.mk ./config.mk; make -j4
   这时候会报错clang: error: : errorunsupported option '-fopenmp'

   
   
   
   

   修改config.md
   export CC = /usr/local/bin/gcc-7
   export CXX = /usr/local/bin/g++-7
   重新编译成功了。
   4.在python中调用
   cd python-package; sudo python setup.py install

   
   
   
   终于安装好了。
