雖然已經安裝，但不能導入scipy

我最近安裝了Python 2.7.11，並且正在安裝一些軟件包。我安裝了numpy雖然pip並試圖安裝scipy但運行sudo pip install scipy，它給了我以下錯誤。雖然已經安裝，但不能導入scipy

所以，我開始通過sudo apt-get install python-scipy安裝它，沒有問題。但是，當我進入python解釋器並嘗試導入scipy時，它說該模塊不存在。我哪裏做錯了？我也嘗試了下面的代碼。

for p in sys.path: 
    if os.path.exists(os.path.join(p, 'numpy')): 
     print p 
     break 
else: 
    print "Numpy does not exist"

導致「/usr/local/lib/python2.7/site-packages」。爲scipy運行相同的代碼說「Scipy不存在」。我認爲這可能是一個路徑問題。任何幫助，將不勝感激。

你用easy_install試過嗎？另外，它似乎缺少ATLAS和LAPACK作爲系統軟件包 – giosans

由於您試圖通過多種方法安裝'scipy'，因此'dist-packages'和'site-packages'中可能有'scipy'。檢查兩個位置並檢查文件夾的權限。 – Nick

@nick，我檢查了'/ usr/lib/python2.7/dist-packages'和'/ usr/local/lib/python2.7/site-packages'，但是我找不到任何scipy文件夾他們。兩種都有Numpy。 – Rahul

我失蹤的是scipy的依賴關係。缺失的圖書館是libatlas-base-dev。一旦我安裝，scipy安裝沒有問題。

感謝大家爲此節省時間。特別提及@ knh170的有用評論。我在那裏找到了答案。

在Ubuntu中，安裝了apt-get install的Python 2.7軟件包放在文件夾/usr/lib/python2.7/dist-packages中。所以，你需要更新你的Python路徑。

export PYTHONPATH="/usr/lib/python2.7/dist-packages:/usr/local/lib/python2.7/site-packages"

此外，您pip install scipy失敗，因爲你沒有安裝庫/包SciPy的依賴。

我試過命令，但無濟於事。 'ImportError：No module named scipy' – Rahul

你能告訴我如何安裝依賴項，所以我可以使用'pip'來安裝'scipy'嗎？ – Rahul

我不知道確切的依賴關係是什麼，但[此答案]（http://stackoverflow.com/a/36000635/250168）列出了scipy，numpy，pandas和其他一些軟件包的依賴關係。 –
