在单元测试中使用numpy.testing函数 是为了对使用NumPy库进行数值计算的代码进行测试和验证。NumPy是一个用于科学计算的Python库,提供了高效的多维数组对象和各种数学函数,因此在进行数值计算时经常会用到它。 numpy.testing函数是NumPy库中的一个子模块,它提供了一系列用于测试和验证NumPy代码的函数。这些函数可以用来比较...
NumPy(Numerical Python的缩写)是一个开源的Python科学计算库。使用NumPy,就可以很自然地使用数组和矩阵。NumPy包含很多实用的数学函数,涵盖线性代数运算、傅里叶变换和随机数生成等功能。本文主要介绍一下NumPy中testing.assert_raises方法的使用。 原文地址:Python numpy.testing.assert_raises函数方法的使用...
