Centos7安装python3、numpy、scipy、matplotlib、pandas等

本文主要是介绍Centos7安装python3、numpy、scipy、matplotlib、pandas等，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

centos7已经自带python2.7.5，这里需要安装python3

第一步：安装依赖包

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：下载python3，这里下载3.6.2

wget https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz

第三步：指定存放目录(/usr/local/python3就是python3的安装目录)

mkdir /usr/local/python3

第四步：解压压缩包，进入该目录

tar -xvJf  Python-3.6.2.tar.xz
cd Python-3.6.2
./configure --prefix=/usr/local/python3

(注：./configure --prefix=/usr/local/python3这句的作用就是将程序安装在/usr/local/python3这个目录下)
第五步：安装python3

make && make install

(注：make是编译，make install是安装)

第六步：创建软链接(将 /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

升级pip(如果需要)

按照提示升级pip，命令：pip3 install --upgrade pip

2.安装其它(直接输入命令)

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

pandas已安装，导入模块却显示ImportError：No module named ‘pandas’，仅需对库进行简单的更新即可解决！

pip --default-timeout=2000 install --user --ignore-installed -i https://pypi.tuna.tsinghua.edu.cn/simple pandas

Pip3 warning

sudo pip3 install -U pip

sudo pip3 install -U numpy grpcio absl-py py-cpuinfo psutil portpicker six mock requests gast h5py astor termcolor protobuf keras-applications keras-preprocessing wrapt google-pasta

sudo pip3 install --pre --extra-index-url https://developer.download.nvidia.com/compute/redist/jp/v42 tensorflow-gpu==1.14.0+nv19.7
