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。

使用这个:
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:
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
已编辑:更正包名称。
下载OpenBLAS的副本并自行编译。使用
make install
将其安装到/usr/local
中。官方存储库中有OpenBLAS和ATLAS包以及其他任何东西,但它们的性能令人怀疑。相关问题 更多 >
