mxnet==1.8.0运行遇到OSError: libopenblas.so.0

问题：

在centos上安装完mxnet，运行gluont遇到这个错误！

解决方法：安装OpenBLAS

参考：CentOS7安装OpenBLAS的简单步骤_u013017173的博客-程序员宅基地 - 程序员宅基地

下载OpenBLAS：

git clone https://github.com/xianyi/OpenBLAS.git

安装：

cd OpenBLAS

make FC=gfortran

sudo make install

链接：(需要管理员, 也可以不用)

ln -s /opt/OpenBLAS/lib/libopenblas.so /usr/lib/libblas.so.3 ln -s /opt/OpenBLAS/lib/liblapack.so.3 /usr/lib/liblapack.so.3

shell执行：

export LD_LIBRARY_PATH=/opt/OpenBLAS/lib:${LD_LIBRARY_PATH}
