1、安装必要的依赖库

sudo yum install unzip
sudo yum install python-devel
sudo yum install epel-release
sudo yum install blas-devel lapack-devel
2、安装numpy

mkdir python370_package
cd python370_package
pip3.7 download numpy
unzip numpy-1.15.2.zip
cd numpy-1.15.2

python370 setup.py install

sudo reboot # 重启重启重启，否则进行测试就报错
python370
import numpy
3、过程中出现的错误：

（1）未重启出现的错误：
