numpy.disutils.system_info.NotFoundError:找不到lapack/blas资源 [英] numpy.disutils.system_info.NotFoundError: no lapack/blas resources found

问题描述

问题:将numpy链接到正确的线性代数库.过程是如此复杂，以至于我可能第六次正在寻找解决方案，而且我不知道出了什么问题.我在Ubuntu 12.04.5上. 我重新安装了blas和lapack，然后使用pip重新安装了numpy.我在系统环境中进行了此操作，然后在virtualenv环境中进行了尝试.这些事情似乎都没有起作用.

Problem: Linking numpy to correct Linear Algebra libraries. Process is so complicated that I might be looking for the solution 6th time and I have no idea whats going wrong. I am on Ubuntu 12.04.5. I reinstalled blas and lapack and then reinstalled numpy using pip. I did that in system environment and then also tried in virtualenv environment. None of the things seem to be working.

这是我的numpy.__config__.show():

这是一个非常常见的错误，有很多解决方案，具体取决于用户的环境和历史记录.我最近按照此处的指示完成了安装BLAS和LAPACK的整个过程: https://stackoverflow.com/a/9173550/3413239 . 我能够成功安装两者.

This is a very common error and has lots of solution depending on the user's environment and history. I recently went through the whole process of installing BLAS and LAPACK as instructed here: https://stackoverflow.com/a/9173550/3413239. I was able to successfully install both.

但是，我最初有以下库:(ls /usr/lib | grep blas)

However, I initially had these libraries: (ls /usr/lib | grep blas)

libopenblas.so.0
openblas-base/
libblas.so.3gf
libblas.3

我应该如何将numpy链接到线性代数库.是否具有所有linaear代数库是强制性的?即lapack，blas，atlas?

How should I link my numpy to linear algebra libraries. Is it mandatory to have all the linaear algebra libraries? i.e. lapack, blas, atlas?

我假设将numpy链接后，所有其他模块(如scipy和Orange)都将起作用.

I am assuming once the numpy is linked all other modules like scipy and Orange will work.

推荐答案

可能有未满足的依赖关系.发生此错误时，我可以通过安装两个软件包来解决此问题:

It's possible that you have unmet dependencies. When I had this error, I was able to fix it by installing two packages:

sudo apt-get install libblas-dev  liblapack-dev
