yum install openssl-devel -y tar xvf Python-3.5..tar.xz
cd Python-3.5.
./configure --prefix=/usr/local/python3.5.4
make
make install
ln -s /usr/local/python3.5.4/bin/python3 /usr/bin/python3 tar xvf setuptools-38.2..tar
cd setuptools-38.2.
python3 setup.py install tar zxvf pip-9.0..tar.gz
cd pip-9.0.
python3 setup.py install python3 -m pip install xgboost
要用xgboost来画图的话，还需要装些东西，重装编下python。
yum -y install tk-devel # 重新编译python python3 -m pip install readline
python3 -m pip install xgboost
python3 -m pip install panda
python3 -m pip install sklearn
python3 -m pip install graphviz
yum install graphviz -y
在命令行里画图，要在import之前使用agg作为后端
import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt
