BLAS/LAPACK未安装：如何安装？

Question

我正在尝试为python2.7运行pip install tsne，但仍然会出现相同的错误。我按照http://bickson.blogspot.com/2011/02/installing-blaslapackitpp-on-amaon-ec2.html上的说明操作，安装了LAPACK/BLAS，我认为这应该解决问题。没什么帮助。我做错什么了？我对巴什不太熟悉。

Ubuntu没有cblas或openblas的二进制分布，这是tsne根据其github所必需的。不过，Ubuntu上提供的ATLAS带有预编译的cblas。

在Ubuntu，debian中，它应该与：

apt-get install libatlas-base-dev 

https://launchpad.net/ubuntu/+source/atlas

如果需要不同的编译器选项，则必须自己构建openblas。

并检查在/usr/lib中是否有libcblas.a
