Scipy新增功能。scipy.test（）失敗，導致許多斷言錯誤
我已經安裝了scipy和numpy，但是我運行scipy.test（）我得到很多測試失敗。 我試圖找到一些共同的原因，我發現幾個：
>>> import scipy
>>> scipy.test()
Running unit tests for scipy
NumPy version 1.6.2

聽起來好像MPI問題或東西，但我我就不會知道。
任何幫助將不勝感激。
Best，Jonathan。
--------編輯--------- 試用scipy.test（詳細= 10）。 大多數測試似乎工作正常。 失敗以錯誤開始。這就是我得到：

我真的很抱歉地說，我不知道是什麼意思的錯誤。
似乎numoy也將失敗。問題是它期望小數點後7-8位，而它的精度爲3.任何想法？我認爲這可能是Fortran編譯器，但我認爲numpy不使用Fortran。 –
Scipy失敗似乎是在OSX上使用錯誤（與Veclib不兼容）與Fortran編譯器有關的典型代碼。任何Numpy的失敗很可能與這些無關 - 很難說沒有看到它們。你可能會發現這些有用的：http://projects.scipy.org/scipy/ticket/1476 http://projects.scipy.org/scipy/ticket/1496 –
