Webb13 mars 2024 · numpy.random.normal 是 NumPy 库中的一个函数，用于生成符合正态分布（也称为高斯分布）的随机数。该函数的语法如下： numpy.random.normal(loc=0.0, scale=1.0, size=None) 其中，loc 表示正态分布的均值，scale 表示正态分布的标准差，size 表示生成的随机数的数量或形状。 Webb1.4.1.6. Copies and views ¶. A slicing operation creates a view on the original array, which is just a way of accessing array data. Thus the original array is not copied in memory. You can use np.may_share_memory() to check if two arrays share the same memory block. Note however, that this uses heuristics and may give you false positives.
