手动安装python3和xgboost

 1 yum install openssl-devel -y
 2 
 3 tar xvf Python-3.5.4.tar.xz
 4 cd Python-3.5.4
 5 ./configure --prefix=/usr/local/python3.5.4
 6 make
 7 make install
 8 ln -s /usr/local/python3.5.4/bin/python3 /usr/bin/python3
 9 
10 tar xvf setuptools-38.2.5.tar
11 cd setuptools-38.2.5
12 python3 setup.py install
13 
14 tar zxvf pip-9.0.1.tar.gz 
15 cd pip-9.0.1
16 python3 setup.py install
17 
18 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。

 1 yum -y install tk-devel
 2 
 3 # 重新编译python
 4 
 5 python3 -m pip install readline
 6 python3 -m pip install xgboost
 7 python3 -m pip install panda
 8 python3 -m pip install sklearn
 9 python3 -m pip install graphviz
10 yum install graphviz -y

在命令行里画图，要在import之前使用agg作为后端

1 import matplotlib
2 matplotlib.use('Agg')
3 import matplotlib.pyplot as plt
