无模块 - 为什么尽管SciPy的安装

如何使用Python和SciPy的获得poissio随机变量？哇...我安装scipy和每个文档我得到没有模块命名为scipy.stats？我在Ubuntu 12.04上。所以......去图无模块 - 为什么尽管SciPy的安装

python-scipy版本为3或2.7的python？你可以只导入scipy吗？ – prgao

你可以'输入scipy''吗？它的版本是什么？ – fjarri

尝试检查哪些文件被安装了'蟒蛇-scipy'，我认为Ubuntu是'dpkg的-L中的python-scipy' –

我觉得SciPy的是要走的路。可能你有一个简单的命名空间可见性问题。由于统计本身首先需要导入它，那么你可以使用函数从scipy.stats

import scipy 
import scipy.stats 
#now you can use 
scipy.stats.poisson 
#if you want it more accessible you could do what you did above 
from scipy.stats import poisson 
#then call poisson directly 
poisson
