centos7已經自帶python2.7.5，這裏需要安裝python3
第一步：安裝依賴包
yum -y groupinstall "Development tools"
yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
第二步：下載python3，這裏下載3.6.2
wget https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz
第三步：指定存放目錄(/usr/local/python3就是python3的安裝目錄)
mkdir /usr/local/python3
第四步：解壓壓縮包，進入該目錄
tar -xvJf Python-3.6.2.tar.xz
cd Python-3.6.2
./configure --prefix=/usr/local/python3
(注：./configure --prefix=/usr/local/python3這句的作用就是將程序安裝在/usr/local/python3這個目錄下)
第五步：安裝python3
make && make install
(注：make是編譯，make install是安裝)
第六步：創建軟鏈接(將 /usr/bin/python3指向/usr/local/python3/bin/python3)
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
升級pip(如果需要)
按照提示升級pip，命令：pip3 install --upgrade pip
2.安裝其它(直接輸入命令)
pip3 install numpy
pip3 install scipy
pip3 install matplotlib
pip3 install pandas
pip3 install statsmodels
pip3 install scikit-learn
pip3 install theano
pip3 install tensorflow
pip3 install keras
pip3 install gensim
