Question

我正在尝试为python2.7运行pip install tsne并且我继续得到相同的错误。我按照http://bickson.blogspot.com/2011/02/installing-blaslapackitpp-on-amaon-ec2.html上的说明安装了LAPACK / BLAS，我认为应该解决了这个问题。什么都没有帮助。我究竟做错了什么？我对bash不熟悉。

Answer 1

Ubuntu没有cblas或openblas的二进制分发，这是tsne根据github所需的。但是，Ubuntu上提供的ATLAS带有预编译的cblas。

在Ubuntu中，debian，应该使用：

apt-get install libatlas-base-dev

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

如果您需要使用不同的编译器选项，那么您必须自己构建openblas。

并检查是否在/ usr / lib

中获得了libcblas.a

已编辑：更正了包名称。

Answer 2

使用此：

sudo apt-get install libblas-dev liblapack-dev

Answer 3

下载OpenBLAS的副本并自行编译。使用/usr/local将其安装到make install。有OpenBLAS和ATLAS软件包以及官方存储库中的其他软件包，但它们的性能是可疑的。

未安装BLAS / LAPACK：如何安装？
