MXNet openblas

最近需要在另一台折腾出来的电脑上装mxnet做些程序验证。一直倾向与openblas，但这次用的是apt-get安装

sudo apt-get install libopenblas-dev libopenblas-base

然后make的时候找不到-lopenblas了，用ln -s 之后正常链接。最后启动的时候却出问题了：

>>> import mxnet as mx
Traceback (most recent call last):

是numpy的问题，看到stack overflow上说是openblas和libatlas冲突了。
担心把前者卸了不能运行，就卸了后面的，但还是出错，试了下卸载oepnblas，果断import成功，
发现mxnet也能导入，测试了下，可以运行操作。
