python-2.7 - 导入 scipy.stats 时出现 ImportError， undefined symbol (scipy 版本 0.14.0)

Question

我刚刚升级到 Scipy 0.14.0 和 Ubuntu 14.04。现在，当我尝试导入统计信息时，我收到了 ImportError。

import scipy.stats as stats

Traceback (most recent call last):

从源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。如果它们不存在，您可以安装它们。我使用标准的 Ubuntu 查找器来找到它们:

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 的源码压缩包，解压压缩包，然后通过 cd 安装到安装目录和

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。
