無模塊 - 爲什麼儘管SciPy的安裝

如何使用Python和SciPy的獲得poissio隨機變量？哇...我安裝scipy和每個文檔我得到沒有模塊命名爲scipy.stats？我在Ubuntu 12.04上。所以......去圖無模塊 - 爲什麼儘管SciPy的安裝

python-scipy版本爲3或2.7的python？你可以只導入scipy嗎？ – prgao

你可以'輸入scipy''嗎？它的版本是什麼？ – fjarri

嘗試檢查哪些文件被安裝了'蟒蛇-scipy'，我認爲Ubuntu是'dpkg的-L中的python-scipy' –

我覺得SciPy的是要走的路。可能你有一個簡單的命名空間可見性問題。由於統計本身首先需要導入它，那麼你可以使用函數從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
