代码：
<em>import</em> <em>scipy</em>
h, p = <em>scipy</em>.<em>stats</em>.randksum(A, B)
报错:
AttributeError: 'module' object has no attribute '<em>stats</em>'
解决：
Scipy, 就像许多其他很大的包一样，不能直接导入，如果需要用某个包，直接导入它。
from <em>scipy</em>.<em>stats</em> <em>import</em> randksum...
Python有一个很好的统计推断包。那就是<em>scipy</em>里面的<em>stats</em>。
Scipy的<em>stats</em>模块包含了多种概率分布的随机变量，随机变量分为连续的和离散的两种。
所有的连续随机变量都是rv_continuous的派生类的对象，而所有的离散随机变量都是 rv_discrete的派生类的对象。
This module contains a large number of probability d
SciPy是一款方便、易于使用、专为科学和工程设计的Python工具包.它包括统计,优化,整合,线性代数模块,傅里叶变换,信号和图像处理,常微分方程求解器等。使用这些功能需要SciPy，但是Python 2.7.12在安装时没有改软件，直接导入会报错：ImportError: No module named <em>scipy</em>.spatial.distance。Python-SciPy 64位版本：

Introduction to Scipy
SciPy函数库在NumPy库的基础上增加了众多的数学、科学以及工程计算<em>中</em>常用的库函数。例如线性代数、常微分方程数值求解、信号处理、图像处理、稀疏矩阵等等,涉及的领域众多。可以进行插值处理、信号滤波以及用C语言加速计算。

求解非线性方程组。 比如求解:
cos(a) = 1 - d^2 / (2*R^2) L = a * r
