Question

我刚升级到Scipy 0.14.0和Ubuntu 14.04。现在当我尝试导入统计数据时，我得到一个ImportError。

import scipy.stats as stats

Traceback (most recent call last):

Answer 1

从源代码安装解决了这个问题。

首先下载numpy和scipy tarball。

然后在我的机器上找到BLAS和LAPACK * .so文件。我在/ usr / lib /中找到了它们。如果他们不在那里你可以安装它们。我使用标准的Ubuntu查找器来定位它们：

find -iname 'libblas.so'
find -iname 'liblapack.so'

所以我为安装设置了一些环境变量。

export BLAS=/usr/lib/libblas.so
export LAPACK=/usr/lib/liblapack.so

然后我下载了numpy和scipy的源代码tarball，解压缩了tarball，然后通过cd安装到安装目录中

python setup.py build
sudo python setup.py install

注意：您可能需要指定安装目录。

欢迎评论。也许有更好的方法。

Answer 2

问题与Scipy缺少对LAPACK的正确引用有关。我按照@jtorca建议的说明进行操作，发现你甚至不需要通过tarball安装。对我来说，以下是诀窍：

apt-get install libopenblas-dev liblapack-dev
export BLAS=/usr/lib/libblas.so
export LAPACK=/usr/lib/liblapack.so
pip install numpy
pip install scipy

导入scipy.stats时的ImportError，未定义的符号（scipy版本0.14.0）
