Numpy scipy.test（）失败，并出现许多断言错误

对Scipy来说是新的

我已经安装了scipy和numpy，但是在运行scipy.test（）时，我发现很多测试都失败了。 我试图找到一些共同的原因，我发现了几个：

>>> import scipy
>>> scipy.test()
Running unit tests for scipy

听起来像是MPI问题之类的，但我真的不知道

任何帮助都将不胜感激

最好的，乔纳森

--------编辑--------- 使用scipy.test尝试了它（verbose=10）。 大多数测试似乎都很好。 失败从一个错误开始。这就是我得到的：
