程序说明:通过运行结果我们可以看到a1、a2、a3这三个结构一致,说明传递参数最终是以元组的形式进行解析的,另外一个就是random和random_sample效果一致。 为了程序规规范性,建议创建ndarray数组过程指定参数size以元组的形式传递。 3.np.random.randint创建随机整数 主要用于创建指定区间范围的整数数据类型数组 函数定义: ...

The main difference between the two is thatGeneratorrelies on an additional BitGenerator to manage state and generate the random bits, which are then transformed into random values from useful distributions. The default BitGenerator used byGeneratorisPCG64. The BitGenerator can be changed by passing...
