Ubuntu16.04安装xgboost

1.Python下安装方法

git clone --recursive https://github.com/dmlc/xgboost
cd xgboost
make -j4
cd python-package/
sudo python setup.py install

如果在import xgboost后，遇到问题

OSError: /home/common/anaconda2/lib/python2.7/site-packages/scipy/sparse/../../../../libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by /home/common/coding/coding/Scala/xgboost/python-package/xgboost/../../lib/libxgboost.so)

解决方法

conda install libgcc

2.Java下安装方法

请先在Python下安装好，因为上面的gcc版本问题会影响到java下xgboost的编译和安装

先更新

git pull && git submodule init && git submodule update && git submodule status

然后参考
